摘要
在汽车中心区转向特性试验过程中,为使试验人员深刻理解中心区转向特性指标表征意义,同时解决中心区转向特性指标数据如何处理的问题。通过结合多年汽车试验经验,概括了转向特性评价指标定义,总结了指标典型值对驾驶员主观感觉的影响;通过运用Origin软件,实现对转向特性指标的数据处理。量化转向特性指标后,汽车试验人员可以通过客观试验数据及主观驾驶感受准确描述出试验车的中心区转向特性,给汽车底盘开发工程师提出设计意见,实现汽车操纵稳定性的提高。
In the test of steering characteristics in central area of vehicle steering wheel, in order to make the test personnel deeply understand the significance of the steering characteristic index of central area, and solve the problem of how to deal with the steering characteristic index of central area. Combined with years of experience, summed up the steering characteristics evaluation index definition, this paper summarizes the influence of typical index value on the driver's subjective feeling, through the use of Origin software, to complete the steering characteristic index data processing. To quantify the steering characteristic indicators, automobile test personnel can describe the test vehicle steering characteristics of central area through the objective test data and subjective feeling of driving, providing the design suggestions for automobile chassis development engineers, improving vehicle handling stability.
