【Abstract】 In view of the fact that the hinge position of the cleaning vehicle frame directly affects the maximum working pressure of the cylinder, on the basis of the analysis of the movement of the cleaning vehicle, the optimization model of the hinge position is established by taking the minimum of maximum working pressure of the hydraulic cylinder as the objective function. Using the genetic algorithm and the toolbox of Matlab, the hinge position is optimized. According to the optimization results, the dynamic model of the working device of tunnel wall and acoustic barrier cleaning vehicle is established, and the force of the hydraulic cylinder before and after optimization is compared. The optimization results show that the optimized hinge position greatly reduces the working pressure of the hydraulic cylinder.更多还原
