This paper presents the responses of the vehicle and track components in terms of vertical forces and displacements. The considered vehicle model is a 10-DOF multi-rigid-body system supported on a track systems that consider three layers of structure. The car body is linked with the bogie through the secondary suspension system contained spring and damper elements. In the model of track, the rail...
The compliant rear-wheel steering (CRS) system can strengthen the characteristic of under-steer to guarantee the vehicle driving safety. One kind of CRS system equipped with the elasticity component of viscoelasticity is studied in this article. The kinematic simulation results show that if the steering stiffness of the CRS system is positive, the direction of compliant rear wheel steering is opposite...
Centrifugal compressor is the vital part of many mechanical systems. The present paper deals with the simulation and the analysis of the fluid performance in two subsonic compressor stages under different rotational speed. The configurations used for the study is two subsonic centrifugal compressors with 60mm and 70mm diameter impeller wheels respectively. Numerical simulation is carried out with...
Aim at the simplified vehicle vertical two-wheeled model, a improved fuzzy PID controller was devoted to the Anti-lock Braking System (ABS). This controller was obtained based on inosculating with fuzzy PID controller and the algorithm of objective function Automatic optimization. A simulation result was gotten through simulation of MatLab Simulink environment. This result shows that the control system...
