摘　　要：文中针对某型叉车在怠速工况下方向盘抖动过大的问题,采用振动测试和模态仿真分析的方法进行研究,发现该叉车方向盘系统在装车条件下的模态参数与发动机的二阶点火频率相接近。通过在方向盘系统与仪表架之间添加减振垫来调整方向盘系统模态,对优化后的叉车整车进行频率响应分析,方向盘处的振动幅值下降了74%。将优化方案进行实车验证,结果表明,方向盘的振动由82.5 mm/s下降到51.6 mm/s,优化方案切实可行。For a stacker,the steering wheel vibrates too much under idling condition.Through vibration test and modal simulation analysis,it is found that the modal parameters of the steering wheel system under loading condition are close to the second-order ignition frequency of the engine.By adding a damping pad between the steering wheel system and the instrument frame to adjust the mode of the steering wheel system,the frequency response analysis of the optimized stacker shows that the vibration amplitude at the steering wheel decreases by 74%.The optimization scheme is applied to the real vehicle verification,and the results show that the vibration of the steering wheel is reduced from 82.5 mm/s to 51.6 mm/s,and the optimization scheme is feasible.
