Research on Vibration Control of Automobile Clutch Damper Torsion Tester with Energy Conservation

Abstract

Since high torsional performance is required to evaluate the durability performance of clutch dampers in automobiles, hydraulic servos with high power consumption are used in torsion testers. In this study, to reduce power consumption, we constructed a test system to evaluate the durability performance of the clutch damper using an electric servo torsion tester. In the evaluation test, it was confirmed that the torsional torque in the specific frequency range was amplified during the adjustment of the inertia on the rotating shaft. Furthermore, we constructed a control system that considers the non-linear torsional stiffness of the clutch damper and confirmed a 90% reduction in power consumption and a stable response to non-linear torsional torque through actual equipment verification.
