摘　　要：转向系统是构成汽车的一个重要总成,在转向系统的设计生产过程中,对其进行台架试验进而分析各项性能是不可或缺的环节。鉴于现行标准对液压助力转向系统的测试和评价方法太过繁杂,提出了以转向器力特性试验为主,灵敏度、回正能力、空载转动力矩、传动效率特性4项试验为辅,设计并进行台架试验,然后根据试验结果对转向器性能进行综合评价的试验评价方法。并且,以某型汽车液压助力转向器为样品,使用该试验评价方法,对其性能进行了试验与分析,验证该方法的可行性。As an important assembly of automobile in the progress of design and production,bench test is an indispensable link for steering system to analyze its various performances.Since the testing and evaluating methods for hydraulic power steering system in current standards are complicated,this paper puts forward a method,which takes the steering gear force characteristics as main test,while four tests of sensitivity,return-ability,no-load torque,transmission efficiency characteristics as supplement,designs and proceeds bench test,and then according to the test results of the performance of the steering gear,obtains comprehensive performance evaluation.In addition,take a certain type of automobile hydraulic power steering gear as sample,its performance is tested and analyzed by using the test evaluation method,and the feasibility of the method is verified.
