Abstract:

Abstract:The working principle of the steering mechanism of tunnel maintenance car was analyzed concretely. Taking the steering moment as research object, based on the genetic algorithm, using the Matlab software, the parameters of the designed trapezoidal steering mechanism were optimized. At the same time, using the large multibody dynamic simulation software ADAMS, the dynamic simulation analysis of the steering mechanism was carried out. The variation curves of various parameters of the steering mechanism in working process (the steering angle and steering moment are included) with time were obtained. The curves were analyzed, and rational improvement proposals were put forward. From the simulation results, the influence of the parameters on the mechanism performance was found, which is useful for selecting optimal parameters and designing more rational steering mechanism.
