The track systems are an important part of the tracked vehicle dynamics modeling. The Riccati Multibody system Transfer Matrix Method (RMSTMM) is adopted to model the dynamics of the tracked systems. During the process, the state variables at the connected ends of the elements within the track systems are transferred through low-order matrices that are independent of the system degrees of freedom, and there are no global dynamics equations with a system inertia matrix. Therefore, using the RMSTMM to analyze the track system has the advantage of facilitating access to the physical quantities associated with the state variables of the components. In conjunction with modeling process, the dynamic characteristics of the track system under different simulation conditions are analyzed, including the applied force of a track shoe running for one revolution and the dynamic tension distribution of the track system. Numerical investigations have shown that based on the RMSTMM, the analysis method of the track system can analyze the dynamic characteristics of tracks at a detailed level, while the method has strong designability and practical. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The damping force of armored vehicle magnetorheological (MR) dampers is controlled by changing the coil current, so whether the coil current can be effectively controlled and fault diagnosis has a significant impact on the working effect of MR dampers. To address this issue, the excitation coil is simplified as an inductance resistance model. By detecting the working current and voltage, the circuit operating state parameters of the MR damper are observed to determine system faults and achieve effective estimation;Based on the estimated results, control algorithms are used to control the working state of the coil circuit, improving the response speed of the system without affecting the stability of the MR damper. Based on heat transfer theory, a temperature rise model of a MR damper can be established. Combined with Bingham model, the relationship between the output force and temperature of the MR damper can be obtained. By using an improved genetic algorithm, the corresponding mechanical parameters can be identified. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The initial disturbance of the projectile has an important impact on the accuracy of artillery shooting, and in order to reduce the initial disturbance and improve the shooting accuracy of large-caliber artillery, a high-speed camera method is adopted to study the initial disturbance of the projectile. The velocity, attitude angle, and angular velocity of the projectile at the muzzle are used to characterize the initial disturbance of the projectile. A binocular camera calibration model is constructed to obtain the camera parameter matrix, and the three-dimensional reconstruction of the markers on the projectile and the gun barrel is performed to obtain the initial disturbance parameters of the projectile and the muzzle vibration parameters. This method has the characteristics of non-contact and strong flexibility, and the obtained experimental data truly reflects the state of the projectile at the muzzle and the muzzle vibration parameters during the period from launch to muzzle exit of the projectile. The obtained data can provide a basis for the structural design of artillery. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The primary objective in aircraft transportation is to minimize turbulent drag, thereby conserving energy and reducing emissions. We propose a sector-shaped counter-flow dielectric barrier discharge plasma actuator, which leverages jet synthesis for drag reduction. A drag control experiment was conducted in a low-speed wind tunnel with a controlled flow velocity of 9.6 m/s(Re = 1.445 × 10^(4)). This study investigated the effects of varying pulse frequencies and actuation voltages on the turbulent boundary layer. Using a hot-wire measurement system, we analyzed the pulsating and time-averaged velocity distributions within the boundary layer to evaluate the streamwise turbulent drag reduction. The results show that the local TDR decreases as the pulse frequency increases, reaching a maximum reduction of approximately 20.97% at a pulse frequency of 50 Hz. In addition, as the actuation voltage increases, the friction coefficient decreases, increasing the drag reduction rate. The maximum drag reduction of approximately 33.34% is achieved at an actuation voltage of 10 kV.

The sparse aperture caused by data loss or unintentional interference is the actual problem in radar imaging process. Therefore, a compressed sensing (CS) based ISAR image reconstruction method with signal support aided is proposed in this paper. Firstly, the signal support is constructed from FFT-based imaging results. Then the signal support is introduced as a prior information into the reweighted function during the CS reconstruction. The simulation results show that, when the azimuth effective aperture ratio is as low as 30 % and signal-to-noise ratio (SNR) equals to -10 dB, the proposed method can obtain clear imaging results like that of complete aperture data. Besides, compared with the traditional CS reconstruction method, the number of false points in the reconstruction results by proposed method is greatly reduced. © 2024 IEEE.

When conducting complex simulation experiments, experimental factor screening is of great significance to improve the effectiveness and efficiency of the simulation. Aiming at the problems of unsatisfactory accuracy and efficiency of existing experimental factor screening methods, a simulation experiment factor screening method based on combinatorial optimization (EFS-CO) was designed. EFS-CO abstracts the experimental factor screening problem into a combinatorial optimization problem, designs the experimental factor evaluation criteria based on the support vector machine model, uses it as the fitness function of the genetic algorithm, and finally obtains the significant experimental factor. At the same time, to eliminate the influence of the randomness of the genetic algorithm on the screening results, the screening results of the experimental factors were determined based on the results of multiple experiments. Finally, the effectiveness of the method is verified by example analysis and comparing the results with the traditional experimental factor screening method. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper presents a longitudinal morphing-aided maneuver control model of an aircraft which could change wing span and change sweep angle, and solved the morphing aircraft control problem of parameter uncertainty and external disturbance by a robust composite control strategy with nonlinear control allocation. Based on DATCOM simulation software and nonlinear least square interpolation, the aerodynamic model is obtained, and established the longitudinal morphing-aided maneuver control model of morphing aircraft. To ensure the maneuverability of the morphing aircraft, a nominal controller which could converge in finite time is designed. The integral sliding mode disturbance observer with super screw control is designed to eliminate the tremor, and the uncertainties and external disturbances are observed and compensated. Then the obtained control signals are assigned to each control inputs through nonlinear control allocation. The simulation result show the effectiveness of the scheme, and prove that the aircraft has good tracking performance by independently changing the shape to assist the traditional control surface. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

A magnetorheological fluid-based recoil device (MRRD) is designed. By designing the structural parameters such as the throttle bar, with the damping controllability of the magnetorheological material, a more ideal control curve is obtained, which can ensure the smallest possible recoil resistance or displacement. The magnetic circuit simulation of the designed recoil system is carried out by using the electromagnetic field finite element analysis software, and the magnetic field distribution of the recoil system under various operating conditions such as different structural parameters, saturation current and damping channels are solved and analyzed to provide a certain basis for the design and magnetic field analysis of the MRRD. The magnetorheological performance test of the system is also carried out. The calculation and test results show that the designed MRRD meets the structural and magnetic circuit design requirements and has good magnetorheological characteristics, it provides a good basis for subsequent experiments and research. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
