全地形履带车辆复合悬挂系统多目标优化研究
Multi-objective Optimal Research on Composite Suspension System for All-terrain Tracked Vehicle
摘要
Abstract
All terrain tracked vehicles are widely used in military,rescue and agricultural fields because of their excellent performance in complex driving environments,but there is relatively little research on their suspension system.In this paper,the multi-objective gray Wolf optimization algorithm is used to optimize the parallel bionic composite suspension system of all-terrain tracked vehicle,so as to improve the ride comfort and ride comfort of the vehicle.Firstly,the multi-scale method is used to solve the system dynamics equations numerically and determine the key objective functions.Secondly,taking displacement transmissibility and natural frequency as optimization objectives,the multi-objective optimization model of the suspension system is established.Finally,an optimization algorithm is used to determine the optimal installation Angle of the spring damper,and the corresponding optimal stiffness coefficient and damping coefficient.The results show that the optimized suspension system has better vibration isolation performance,which verifies the effectiveness of the method in the optimization of complex suspension system,provides theoretical guidance for the parameter setting of simulation experiment,and provides a new idea for solving similar engineering problems.关键词
