摘要
为实现某轻型客车复合材料板簧连接结构的匹配设计,通过多体动力学仿真获取了复合材料板簧连接结构各方向上的极限载荷,提出了复合材料板簧连接结构的参数匹配设计方法。根据连接结构的失效模式,提出了连接结构铺层方案的设计原则,并对铺层方案进行了优化。对优化后的连接结构进行台架疲劳试验和实车可靠性试验。结果表明,所设计的复合材料板簧连接结构满足装车要求,这对保证复合材料板簧总成的可靠性,促进其推广应用具有重要意义。
In order to fulfill the matching design for the connection structures of the composite leaf spring in a light bus,the ultimate loads of the connection structures along different directions are obtained through multi-body dynamics simulation,and the parameter matching design method for the connection structure of composite leaf spring is proposed.According to the failure mode of connection structures,the design principle for the layup scheme of connection structure is proposed with the layup scheme optimized.Both fatigue bench test and real vehicle reliability test on the connection structures optimized are carried out.The results indicate that the designed connection structures of composite leaf spring can meet the requirements for installation on vehicles,having a great significance to ensure the reliability of composite leaf spring assembly and promote its popularization and application.
