Simulation of the clutch pedal return time for light commercial vehicles

Clutch pedal return time is one of critical parameter and requirement of the clutch system validation. It helps to understand the response of the clutch actuation system during repetitive vehicle operation. Clutch release system has several components such as diaphgram spring finger, slave cylinder, clutch hose and pipes, master cylinder and clutch pedal. In the thesis, the simulation of clutch pedal return time has been established. It has been built on GT-SUITE commercial software. The entire clutch system has modelled and flow section has been created and optimized for light commercial vehicles. In the simulation, the driver presses the clutch pedal, holds his foot on the pedal for a second and quickly releases the clutch pedal. Then the pedal returns it initial stationary position by itself. The return time of the pedal is determined at the end of the simulation. The simulation works in correlation with vehicle test.
