ABSTRACT

With the progress of science and technology, people's requirement for automobile performance is getting higher and higher. In this paper, the improvement of ride comfort and handling stability of mining vehicles is studied. The constraints, including upper and lower bounds and inequality constraints, are set for the actual working conditions through the parametric optimization design of kinematics objective function. It avoids the problem that the traditional optimization method stiffness optimization value often appears in the largest or small boundary area. When designing the control law, it is required to comprehensively consider various factors, reasonably select the weighting coefficient in the semi-active suspension performance index function, and control the motion response to improve the ride comfort and steering stability. It has a greater priority in the optimization process, that is, the goal is first guaranteed; and the goal with a smaller weighting factor is considered on the basis of achieving a larger weighting factor.
