Joint Simulation and Optimization of the Lifting Platform of Anti-riot Vehicles Based on the Mechanical-Hydraulic System

Because the scissor lifting structure of the lifting platform of the traditional anti-riot vehicles has the problems that momentary thrust force is too large and the oil pressure of hydraulic system is too high, these problems directly affect the performance of the lifting platform. In this paper, ADAMS and AMESim were used to establish respectively the virtual prototype model and the hydraulic circuit model of the lifting platform of an anti-riot vehicle, and the analysis was carried out by an co-simulation. Based on the structure of the scissor lifting structure, the sensitivity analysis was used to determine the design variables. The hinge position of the cylinder was optimized by taking minimum of the lifting momentary thrust force and the oil pressure as the goal. Compared with before optimization, the thrust force of the lifting cylinder was obviously reduced, the maximum oil pressure was obviously decreased, and the stability of the lifting operation was improved.
