Abstract: This paper first introduces some failure problems found in clutch system assembled in a commercial vehicle during development verification processes. Focus on using CAE simulation and test technology to optimize and verify designs, which reduces time costs for solving test problems. At the same time, by inducing analysis processes and methods, it provides useful references for analyzing and solving failure problems with other vehicle parts, it provides technical path and test data for the optimization of clutch support scheme in a commercial vehicle.

Key words: Commercial vehicle; Transmission; Clutch; Support scheme; Test validation; Design optimization
