摘　　要：车架疲劳试验是矿用车辆改进设计中的一个重要步骤,通过疲劳试验能测试车架及相关部件寿命,优化结构设计。为满足矿车车架疲劳试验要求,提出了利用非对称阀控制非对称缸实现车架疲劳试验台力加载的方案。通过系统的静、动态特性分析,以及基于AMESim的仿真,确定了控制系统的主要设计参数,并在此基础上,开发了试验系统。系统的试验结果表明,其性能指标达到预期要求。该设计方法对于类似工程实际应用具有一定的参考价值。To optimize the design of structure, the life of the mine vehicle frame and related components can be got by the fatigue test, which is one of the most important steps during the vehicle design process. In this paper, the scheme of asymmetric valve control asymmetric cylinder to meet therequirement of mine vehicle frame fatigue test is proposed. By the analysis and calculation of system＇ s static and dynamic characteristics, the main parameters of control system are determined based on the AMESim simulation. The result shows that the performance of the system meets the technical requirements. The design method has some reference value for similar engineering applications.
