Experimental Analysis of Manual Transmission Gear Rattle Dynamics and its Inhibition Measure
摘要
Abstract
Dynamic characteristics,generation mechanism and inhibition measure of manual transmission gear rattle were analyzed systematically by specialized bench test and vehicle experiment.Firstly,experimental condition and sensor layout of manual transmission gear rattle were designed and considerations for specific experimental operation and data postprocessing were clarified.Secondly,characteristics measurement of the original clutch damper was implemented on a special test bench,and vehicle experiments of manual transmission gear rattle were conducted on two steady conditions including idling and creeping condition.Finally,clutch damper parameters optimization was proposed to inhibit severe gear rattle phenomenon and then it was validated by vehicle experiments.The research achievements would contribute to improving clutch damper products and solving gear rattle problem in the engineering practice.关键词
