To reveal the performance of mechanical seal with herringbone spiral groove, a CFD model was established. Effects of structural parameters on the mechanical seal performance were analyzed, such as groove number and spiral angle. Then, these structural parameters were optimized by liquid membrane opening force and drainage volume. The results show liquid metal flows into the miter groove from both ends under the action of viscous force, a bearing area is formed when the liquid metal reaches the top, and there is a pressure peak in the bearing area.

The modeling method of freehand sketch based on conceptual design is the focus research in CAD. Though projection and mapping algorithm, freehand 2D curved surface was identified and mapped to 3D space to conceive target 3D curved surface. Man-machine interactive technology was used to realize on-line correction of a curved surface. At last, a software system for identifying space curve based on freehand sketch was designed. The experiment result indicated that the method could conceive ideal space curve and curved surface for user more freely and rapidly.

Fracture is a common disease in medical clinic, which is often diagnosed based on medical images. In order to reduce the reading time of experts and reduce the misdiagnosis rate, a medical auxiliary detection system for upper limb bone abnormality detection is proposed in this paper. The convolution neural network method is used to detect and diagnose the upper limb bone. In this paper, the open mura data set is used in the data set, and the adaptive contrast restriction algorithm is used to process the bone image, so that the bone edge is more obvious and the focus position is more clearly visible. Then, the upper limb bone injury data set and the upper limb bone position classification data set are constructed respectively. For medical image recognition, this paper proposes an IDNet network based on perception and Densenet: in the task of upper limb bone injury classification, the accuracy of IDNet reaches 0.92;In the classification task of upper limb bone parts, the accuracy of IDNet reached 0.99. © 2022 IEEE.

In order to improve the automatic operation level of welding robot, which is very important for weld recognition, this paper proposes a method based on deep learning to identify and locate target welds for the determination of weld types and weld positions in images. Through the idea of classification and then segmentation, the three weld types used in this paper can be accurately segmented. Firstly, MobileNetV3, a lightweight network with a special bneck structure, is used to classify the three images, and SeGAN neural network is used to segment the weld images to obtain the results. In this paper, a few sample images are used for training, and then a higher accuracy is achieved by expanding the sample. The experimental results show that the accuracy of the classification results reaches 99.39%, which is 3.74% higher than that of VGG, and the accuracy of the positioning results can reach 95%, which proves the effectiveness of the method and has important significance in industrial automation welding. © 2022 IEEE.

A diagnostic system was setup to test the ferroelectric micro-plasma thruster(FMPT). The V-I characteristic of the FMPT was measured. The optical spectrum of microplasma generated in FMPT was obtained. Additionally, the electron temperature has been found to be ∼3.43 eV from atomic Boltzmann plots of neutral Ag I lines. © 2017 IEEE.

This paper attempts to use a simple and practical method based on the finite element theory and orthogonal design for the optimal structural parameters of machine tool bed. Dynamics finite element model of MCH63 machine tool bed has been established with the finite element analytic technique in order to improve the dynamic characteristics. The thickness of the ribs are looked as the design variables, the orthogonal design is used to optimize the natural frequency and the total mass. The simulation result indicates that the method is simple, effective and feasible.

Configuration optimization of physical prototype for 6-3-3 parallel mechanism was modeled mathematically, and then an idea of embedding finite element method in optimization algorithm was presented for solving optimizing model. In optimization design toolbox of ANSYS software, configuration optimization of the parts for the mechanism was realized by means of establishing parameterized model with parts, defining design variables, restraint and objective function. The investigation provided theoretical basis for lightweight part design with physical prototype of the parallel mechanism.

Research on grasping force optimization of dexterous robot hand is an important topic in manipulation planning, it is an effective way to improve the grasping precision and save energy. Based on the force manipulability ellipsoid of manipulator, this paper defines force directional manipulability of multi-fingered dexterous hand. On the condition that the operational configuration is known, and taking the force directional manipulability as the objective function, the optimization on force transmission direction of dexterous hand is presented. A numerical example of three-finger dexterous hand is presented that the force transmission performance and the best transmission direction of dexterous hand on a given configuration are obtained.

In order to allocate tasks and optimize resources well in dynamical manufacturing environment,the model for task allocation is established. An adaptive genetic algorithm(AGA) is applied to deal with it. A machine-based encoding approach is also adopted. The simulation results testify the validity of this method,and therefore the task allocation and resources optimization problem could be dealt with efficiently.
