汽车被动安全性试验研究 总被引:9,自引:0,他引:9
在深入调研国外资料的基础上,根据有关国际国内标准,结合我国国情,自行设计并建成了国内第一座汽车撞击试验台。该试验台既能进行整车撞击,又能进行重复性模拟撞车环境的台车撞击试验。试验中采用了电测量和图象测量,并应用了数字化图象处理技术,取得了满意效果。试验结果还用理论模拟计算进行了对比验证。初步探索出一条在我国开展汽车被动安全性研究的途径。 相似文献

A new ideal mechanical one-port network element named the inerter was recently introduced, and shown to be realisable, with the property that the applied force is proportional to the relative acceleration across the element. This paper makes a comparative study of several simple passive suspension struts, each containing at most one damper and inerter as a preliminary investigation into the potential performance advantages of the element. Improved performance for several different measures in a quarter-car model is demonstrated here in comparison with a conventional passive suspension strut. A study of a full-car model is also undertaken where performance improvements are also shown in comparison to conventional passive suspension struts. A prototype inerter has been built and tested. Experimental results are presented which demonstrate a characteristic phase advance property which cannot be achieved with conventional passive struts consisting of springs and dampers only. 相似文献
