This paper presents the adaptive hydraulic active suspension applied to the six-wheel off-road vehicle. Both four-link articulated mechanical structure and power transported hydraulic system are constructed. Nonlinear mathematical model is established for the nonlinear uncertain hydraulic system. The advantages of self adaptive suspensions and active suspensions are combined and introduced into the...
In this paper, a model of the large crane lifting system has been developed in the AMESim environment. The comparison between the simulation results and the experimental data shows good agreement in both time and frequency domains, indicating the correctness of the model. Furthermore, the causes of pressure pulsations of the lifting system are described by means of dynamic simulation and experimental...
A wheeled mobile vehicle with 2 DOF articulated frame (2DWAV) is presented in this paper. This vehicle can improve the rough-terrain mobility and stability by reshaping its articulated frame. The analysis completes about the influence that the stability of single body's worked on the entire frame stability. For the unique 2 DOF articulated frame, we propose the new concept of correlative stability...
This paper introduces a certain type of special hydraulic truck crane counter balance valve structure and working principle of the establishment of a counter balance valve using AMESim software model and carry out time-domain and frequency domain characteristics of the simulation analysis, identify the issues affecting the performance of the main counter balance valve structural parameters of the...
