摘要
针对转向系统及其各零部件对标试验无法满足项目时间节点要求,造成研发效率低、失误率高等问题,结合转向系统的受力特点以及悬架K&C特性,基于CEPS转向系统建立其在开、关助力2种模式下的刚度数学模型,通过与实测数据进行对比,对数学模型的计算精度和误差进行分析验证。结果表明:该数学模型计算误差在合理范围内,精度满足设计要求,在降低试验成本、提升研发效率的同时,有效解决了转向系统研发初期缺乏对标数据参考的问题。
Aiming at the problem that benchmarking test of steering system and its components can not meet the time point of the project,which results in lower R&D efficiency and high error,combining with the force characteristics of steering system and K&C characteristics,the stiffness mathematical model of steering system is established under on&off assist modes based on CEPS steering system.The calculation accuracy and error of the mathematical model are analyzed and verified by comparing with the measured data.The results show that the calculation error of the mathematical model is within a reasonable range,and the accuracy meets the design requirements.While reducing the test cost and improving the research and development efficiency,the problem of lack of reference for benchmarking data in the early research and development of the steering system is effectively solved.
