摘　　要：设计了齿轮齿条式转向系统五轴试验台。在分析转向系统基本要求、整车转向系统评价标准及转向器行业标准的基础上,提出了该转向系统五轴试验台需实现的试验项目及基本功能,并对电液伺服加载、驱动装置控制、加载装置静压支撑等关键技术进行了探讨。对所研制的转向系统五轴试验台进行验证的结果表明,该试验台能够有效进行齿轮齿条转向系统性能匹配及耐久性测试评价,试验结果与实车试验结果具有较好的一致性。Five channel rack and pinion steering system test bench is designed. Based on the analysis of basic requirement of steering system, evaluation criteria of vehicle steering system and steering industry standard, we put forward test items and basic functions of this five channel steering system test bench, and investigate the critical technologies, i.e. electro-hydraulic servo loading, drive unit control, loading unit hydrostatic bearing, etc.. This test bench is tested to verify that it is capable of making performance matching and durability test evaluation for rack and pinion steering system, and the test results agree well with real vehicle test results.
