【摘要】 在考虑轮胎纵向和侧向动反力的基础上,建立弹性支撑条件下的整车振动综合模型,利用导弹剪切闭锁力作为系统激励,分别在综合模型和不考虑轮胎纵向和侧向动反力的简化模型上进行仿真计算,并对试验结果进行对比。结果表明,轮胎的侧向和纵向动反力对系统振动有重要影响,不能忽略。更多还原

【Abstract】 On the basis of tyre forces of both lateral and lengthways,a buffeting aggregative model under elastic support conditions was established. Using the missile’s cut closed ability as the system’s prompting,while made simulation calculation respectively on the comprehensive model and the simplified model that without regard for the tyre’s lateral and lengthways counterforce,and compare the calculation result with the experiment result. Analysis shows the lateral and lengthways tyre forces play an important role in the vibration and it can not be ignored.更多还原
