摘　　要：为了检测循环球式转向器的疲劳性能,在分析转向器工作原理的基础上,运用电液伺服材料试验机INSTRON 1251试验台与计算机控制单元,设计了转向器疲劳试验系统。研制了转向器疲劳试验工装夹具,系统加载动态响应良好,达到了转向器疲劳试验参数要求。试验运行表明:该试验设计实现了转向器疲劳性能测试,操作简便,控制精度高,为转向器结构设计与强度评估提供了基础技术支持。In order to detect the fatigue property of the recirculating ball steering gear,on the basis of analyzing the working principle of the steering gear,the electro-hydraulic servo testing machine INSTRON 1251 system and computer control system are used to design the steering gear fatigue test system. Steering fatigue test fixture is developed,and the test system has a good dynamic response on loading,it meets the requirements of the steering gear fatigue test parameters. Test operation condition shows that : the experiment design implements the steering gear fatigue property test,and it has a easy operation and high control precision,and provides the basic technical support for the assessment of steering gear's structure design and strength estimate.
