摘要
摩托车曲轴总成的动平衡对摩托车发动机以及整车的动平衡有相当大的影响,在检测原理上目前很多厂家仍采用传统的检测方法。本文研究了摩托车曲轴总成动平衡一种新型检测系统设计与利用小波分析对数据进行处理相结合的方法。介绍了新型摩托车曲轴总成检测系统的原理与构成,以及小波分析理论的简介,包括小波变换的定义,核心算法以及信号去噪。针对目前检测方法中信号处理方式,讨论了小波分析在摩托车曲轴总成检测过程中的应用,并进行了实验。结果表明,应用此方法构造的摩托车曲轴总成动平衡检测系统得到了满意的效果。
The method that the dynamic balance checking and measuring technique for crankshaft component of new type motorcycle is combined with data analyzing by wavelet analysis. During of the design of the system of dynamic balance checking and measuring technique for crankshaft component of the new type motorcycle, under the control of the main control, the vibration signal acquisition of the crankshaft component by sensors, compute and etc. The unbalances signal that using by checking the crankshaft component is bringing up by wavelet analysis arithmetic at the same time. The system of dynamic balance checking and measuring for crankshaft component of motorcycle has obtained the satisfied result by using the above algorithm.
