The NVH Phenomena Analysis in Corn Harvester -Based on Vibration Dose and A-meter-weight Noise
摘要
Abstract
To improve the ride comfort of Agricultural machinery , based on GB/T 18697-2002 and ISO 2631 , A vibra-tion and noise testing measurement system for corn harvester was established .By using MATLAB , the processing to ac-celeration time-history series were completed .vibration dose and A-meter-weight noise were chosen to evaluate the ride comfort , vibration dose is used to evaluate the vibration and A-meter-weight noise is used to evaluate the noise .Depen-ding on the two indexes , A final evaluation on the corn harvester was made and some improve guidance were given .关键词
