Modelling Cavitation in Viscoelastic Thin Lubricating Films 5th

Modelling Cavitation in Viscoelastic Thin Lubricating Films

Lubrication via polymer enhanced oils helps prevent excessive energy and material losses in mechanical components such as bearings and gears. The addition of these polymers presents strong non-Newtonian characteristics in the lubricating film, such as shear thinning and viscoelasticity that must be taken into account at high contact load and surface sliding speeds. In this work, we utilize computational methods to model the pressure distribution, governing the maximum load carrying capacity, in a hydrodynamically lubricated contact in which (i) the lubricant viscoelasticity cannot be neglected and the (ii) lubricant film can present a gaseos (or vaporous)-liquid mixture region due to a drop in the film pressure below the cavitation pressure. For this we employ the viscoelastic Reynolds equation (Ahmed & Biancofiore, Journal of Non-Newtonian Fluid Mechanics, 292, 104524, 2021.), (i) modified appropriately to account for lubricant phase change, and (ii) adapted for the robust Fischer-Burmeister-Newton-Schur (FBNS) algorithm to model the cavitation appearance. We observe in several geometries, mimicking journal bearings and pocketed profiles, an improvement in the tribological performance (higher load and lower friction coefficient) as viscoelastic effects are strengthened.

In this paper, a Boundary Element methodology is presented to assess viscoelastic circular contacts in steady-state conditions, when the interacting pair shows both a low and a high level of conformity. The approach is fully general, able to deal with any real viscoelastic material, with a continuous spectrum of relaxation times, and it is based on the definition of an ad-hoc derived Green's function, which captures the circular feature of the domain. At first, the conformal contact between a rigid cylindrical punch and a holed linear viscoelastic space is studied, and the viscoelastic contribution to the overall friction is analyzed;then the BE methodology is deployed to investigate the response of a polymer roller bearing operating in steady-state conditions. The assessment of such a problem is fundamental from an industrial point of view, as we show that, differently to the purely elastic case, some of the rollers in the load zone may lose contact with the raceways at certain angular speeds: this circumstance may lead to dramatic changes of the bearing capacity and, in turn, to severe consequences on the system operation.

In a project funded by the Ministry of Regional Identity, Local Government, Building and Digitalization of the State of North Rhine-Westphalia, automation in the construction industry is to be advanced. The goal is to realize essential parts of the shell based on a digital building model, using robot technology. After the realization of the automated masonry, the automatic creation of ceilings with cable-driven parallel robots shall be developed. An important step towards economic competitiveness is the increase in processing speed and quality. The optimization of the construction material gripping and the corresponding detection processes are crucial for cost-effective implementation. The approach proposed here utilizes machine vision methods to accelerate the automated shell creation, additionally enabling quality assurance. The paper reviews the state of quality assurance and machine vision methods in the context of automated building construction. It then outlines the approach to process improvements, describing a concept for image-based component recognition. The results demonstrate the potential benefits of incorporating machine vision into the cable robot system, discussing implications for efficiency and overall construction quality. The findings contribute to the ongoing efforts to integrate automation seamlessly into the construction industry.

In humanoid robot design, the output capacity of the knee joint plays a crucial role in determining the robot's load-carrying ability. Therefore, when the joint's driving torque remains constant, changing the transmission ratio of the joint is an effective means of enhancing the robot's load-carrying capacity. This paper proposes a knee joint mechanism design that dynamically adjusts the joint's output speed and torque based on the joint's output requirements. Built upon a linkage transmission mechanism, this method involves altering the installation position of the linkage on the thigh and the shank to adjust the joint's output speed and torque. Through dynamic simulations, this approach can expand the load-bearing capacity by 2 to 10 times, providing a mechanism that adapts to the demands of joint output.

Vibrational transport of various objects including granular and other bulk particles is highly used nowadays especially in the technological industries due to its high efficiency and reliability. There are various methods and approaches that utilize the vibrational transport of objects. This paper investigates the transportation of objects on a harmonically vibrating horizontal plane when dynamic dry friction manipulation is applied to achieve an asymmetry that results in the motion of a body along a longitudinal direction. Using this vibration method, we could transport the objects by applying dynamic dry friction manipulation where friction asymmetry was created. A mathematical model was carried out using the Lagrange equation to prove the feasibility of the applied method, and the second-order differential equations were solved using MATLAB. The results and findings have shown that the velocity and the direction of the moving objects can be controlled by changing and modifying the control parameters of the function of dynamic dry friction manipulation. This transportation method is highly beneficial for industries that handle a wide range of masses of objects to be transported and require high levels of reliability and durability.

This paper describes the development and implementation of lateral and longitudinal control algorithms for a low-cost self-driving vehicle within the Nebrija Autonomous Vehicle (NEVA) project. For lateral control, a Pure Pursuit algorithm was implemented using a Python script. This geometric approach leverages GPS data to define a path and calculates the steering angle required to reach a designated goal point along the path. Longitudinal control utilizes a PID controller to achieve a target speed. This target speed is adjusted based on upcoming path curvature data obtained from the Pure Pursuit algorithm. The vehicle can thus modulate its speed for approaching curves or straighter sections. The performance of these algorithms was evaluated through real-world road tests, demonstrating their reliability and effectiveness for the NEVA vehicle.

In the automotive industry, tyre friction plays a critical role in maximizing safety and performance, while reducing total vehicle energy consumption. Rubber friction is a phenomenon still not totally understood, since it is influenced by a vast array of linked factors, involving polymer viscoelastic characteristics, surface roughness, and the conditions under which the contact occurs. In this context, the most reliable way to quantify the friction arising at the tread-road contact is empirical analysis via specific test benches called friction testers. This paper presents a new linear friction tester (LFT) for friction and wear tests developed by the Applied Mechanics Research Group of the Department of Industrial Engineering of the University of Naples "Federico II". The rig was designed to strike a balance between production costs and versatility of use, aiming to accurately reproduce rubber-substrate interactions over a wide range of working conditions. Along with the machine, a testing methodology has been developed and applied to a first case study, in order to demonstrate the degree of repeatability that can be achieved. A tyre tread compound has been tested under various sliding velocities, temperatures, and contact pressures, paying particular attention to any deviation between the runs. The preliminary results indicate the high promise of the device in providing crucial data for validating analytical friction models presented in scientific literature.

This paper deals with the modelling of an electromechanical needle gripping system using an electromagnet. The system will be part of a special sewing machine for creating a decorative stitch. To sew this type of stitch, a special floating needle is used, which two mechanical systems of needle bars pass through the sewn material in such a way that a perfect imitation of a hand stitch is created. The proposed electromagnetic control of the needle gripping is intended to replace the existing mechanical system, which generates high levels of vibration and noise. This largely contributes to the total noise level of the sewing machine, which needs to be reduced. In this work, a mathematical model of the needle bar is proposed for the Matlab Simulink environment. The model describes the mechanical parts of the needle bar and the links between them, the kinematic excitation of the needle bar, the electromagnet that is used to control the grip and release of the needle in the needle bar, and the electrical circuit that supplies the electromagnet.

The recent popularity of electric kick scooters, as affordable, eco-friendly, and lightweight vehicles, places them on the spotlight of urban mobility. The upright riding position, along with the vehicle's low mass, necessitates a thorough understanding of the entire system, including human motion analysis. The aim of the present study is to evaluate the impact of some electric kick scooter and rider characteristics on the rider kinematics in a real driving scenario. Fourteen healthy young participants are recruited for the experimental campaign. The on-road tests consist of driving on seven speed bumps at two different constant speeds. During the tests, the angular motion of selected human body segments and the pitch motion of the electric kick scooter are monitored: these magnitudes are used to conduct a statistical analysis focusing on the influence of vehicle speed and rider's gender, mass, and forward foot. Overall, results suggest that the dynamics around the medio-lateral axis of both the vehicle and the human body is influenced by the riding speed, the gender, and the mass. Moreover, a symmetrical foot position on the deck promotes greater rider stability.

Mobile collaborative robots are more and more common in the industrial scenario, increasing the workspace of collaborative manipulators and, thus the shared workspace. This work compares different admittance controllers for mobile collaborative robots. In particular, we focused on an application where a human operator manually moves a mobile collaborative robot by applying forces to a collaborative manipulator attached to the mobile platform. Three different forms of admittance control were presented and tested with experiments on a real mobile robot. Finally, the capabilities of these controllers were compared.
