某300吨级矿用自卸车悬置系统分析和优化

Analysis and Optimization of Mounting System of a 300-ton Mining Dump Truck

针对某300吨级矿用自卸车存在振动和噪音过大的问题,通过原地实车测试,依据数据分析,找出了悬置系统隔振能力的薄弱点,为了进一步提高驾乘舒适性和减小振动带来的影响,从两个方面对现有悬置系统进行优化分析:一、对悬置支撑点位置进行优化;二、对减震器进行重新匹配选型。本论文综合运用声震测试、优化设计理论与技术,对该车动力总成悬置系统进行动态分析、优化设计与工程化改进,通过试验数据对比分析,提高悬置系统隔振性能。

Considering the problem of a 300-ton mining dump truck with excessive vibration and noise,the suspension system support point position was adjusted through analysis and calculation to improve the ride comfort and reduce the vibration with suitable shock absorbers.In addition,dynamic analysis,optimization design,and engineering improvement were carried out on the suspension system of the vehicle with the sound and vibration test and optimization design theory and technology,improving the vibration isolation performance of the suspension system.
