动态称重系统振动信号分析研究

摘要

The result of dynamic weighing of vehicles is greatly related to driving ways of vehicles. Irregular vibration noise produced in driving process of vehicles will add dynamic weighing difficulty and usually cause inconsistency of weighing result with the actual weight of vehicles.This paper introduces the method of wavelet transform to reduce noise and applies it for dynamic weighing to study influences of reduction of vibration noise on dynamic weighting accuracy.%对车辆进行动态称重时，称重结果与车辆的行驶方式有很大关系。车辆行驶过程中产生的不规则振动噪声会使动态称重难度增加，往往造成称量结果与车辆实际重量不符。介绍小波变换降低振动噪声的方法，并将其用于动态称重，以研究降低振动噪声对动态称重精度的影响。
