【摘要】：通过建立传递路径模型,应用传递路径分析方法针对某轻型客车方向盘怠速抖动进行了传递路径分析。阐述了传递路径分析的理论推导过程以及在实际问题中的应用方法。针对发动机悬置及排气悬吊的各条结构传递路径进行了传递函数获取以及工作载荷的识别,并最终获取了各结构传递路径的贡献量。通过综合考虑贡献量幅值及相位因素并对其进行分析,最终确定了发动机后悬置的X向及Z向对怠速方向盘抖动的贡献量最为突出,为怠速方向盘抖动的改善工作指明了方向。
[Abstract]:The transfer path analysis method is used to analyze the idle jitter of the steering wheel of a light bus by establishing a transfer path model. The theoretical derivation process of transfer path analysis and its application in practical problems are described. The transfer function and working load identification of each structure transfer path of engine mount and exhaust suspension are obtained and the contribution of each structure transfer path is obtained. By synthetically considering and analyzing the factors of amplitude and phase of the contribution, it is determined that the most outstanding contribution to idling wheel jitter is the X direction and Z direction which are mounted at the back of the engine, indicating the direction for the improvement of idling steering wheel jitter.
