客车纵倾问题研究分析

Research and analysis on passenger vehicle longitudinal pitch problem

以中型客车为研究对象,建立整车纵倾数学模型,对建立的模型进行仿真研究,得出研究对象在最强制动工况下的纵倾角,该纵倾角大于行业推荐值。针对研究对象提出了提高抗纵倾能力的改善措施,并进行计算验证。最后,系统总结了整车提高抗纵倾能力的相关措施。

Taking medium-sized vehicle as the research object,simulation research on the established mathematical model of the vehicle′s longitudinal pitch was conducted,and the pitch angle of the research object under the strongest braking conditions was obtained,which was greater than the industry recommended value.Improvement measures were proposed to enhance the anti-longitudinal pitch ability of the research object,and calculations were conducted for verification.Finally,the relevant measures to improve the vehicle′s anti-longitudinal ability were summarized systematically.
