Design and test analysis of inertia system of test bench for tire performance

为了研究轮胎静态和动态性能,提出了轮胎应力应变、高速性能、耐久性能、制动性能和强度性能测试试验方案,按照试验目的和要求对轮胎综合性能试验台进行了总体结构设计,重点研究了试验台惯性系统的结构设计和参数确定方法.利用SOLIDWORKS和ADAMS/View建立了试验台的动力学仿真模型,参照车辆滑行试验方法对试验台惯性系统进行了仿真分析和实车道路试验.车速变化和滑行距离的仿真分析与道路试验结果一致性检验表明试验台惯性系统结构满足工程实际要求.验证了试验台惯性系统结构设计的合理性和参数确定方法的可行性,实现了试验台惯性系统与汽车质量的精确匹配.

In order to study the static and dynamic performance of tire,a bench test strategy was put forward,which included stress-strain analysis,high-speed performance test,durability test,braking performance test and mechanical properties test.Based on the requirements of tire performance tests,a test bench for comprehensive tire performance was framed,and the design method of inertia system was systematically represented.The dynamic simulation model of test bench was built up using SOLIDWORKS and ADAMS/View.The simulation analysis and road test of inertia system for test bench were conducted according to vehicle coast-down test method.The consistency check of simulation and road test results was completed,which meet engineering requirement and verified the structure rationality of inertia system of test bench.The accurate match between the inertia system and the mass of test vehicle was realized through the tire test bench.
