摘要

摘要: 目前车辆悬架关键紧固件的强度设计大多依赖于经验公式,难以保证其可靠性。如何保证足够的设计强度一直是关键紧固件设计与选型的难题。首先建立了极限工况下纵向、侧向、垂向和复合类整车模型,通过整车道路试验修正模型参数,利用修正后的整车模型求解轮胎受力。其次改进了ADAMS悬架模型,基于轮胎受力得到各极限工况下的关键紧固件受力,根据最大值进行强度设计与选型。应用实例表明,该设计方法能保证悬架关键紧固件的强度设计与选型具有足够的可靠性,满足各极限工况下的使用要求。

Abstract: The strength design of vehicle suspension key fastener is mainly dependent on empirical formula currently, thus it is difficult to ensure the reliability of design. How to ensure adequate strength of fastener has been the key problem of key fastener design and selection. Firstly, four analytical models of longitudinal, lateral, vertical and composite vehicle models under extreme conditions were established. Parameters of vehicle model were modified according toteh results of road testing, and tire forces were solved by using numerical methods. Then the suspension model in the ADAMS software was improved, and the key fastener forces under each extreme condition were obtained based on computer simulations.Finally, the strength design and selection for key fasteners were executed according to the maximum force. Application examples show that this design method is able to guarantee the strength design and selection of suspension key fastener with sufficient reliability and it meets the requirements of each extreme condition.
