The topology optimization is performed to reduce the material of a clutch fork. The Effects of topology optimization on the frequency of clutch fork are to be determined by comparing the frequency of the original clutch fork and optimized clutch fork by using modal analysis using ANSYS 19 software. Key Words: Modal Analysis, Topology Optimization, Frequency, Clutch Fork, ANSYS 1.INTRODUCTION The clutch is an essential part of the vehicle. The clutch system is consists of components such as Pedal, Master cylinder, Slave cylinder, Clutch fork, Throw-out bearing, Pressure plate, Clutch disc, flywheel. To transfer motion from pedal to clutch fork is done by using a hydraulic system or a cable. The function of the clutch fork is to push the throw-out bearing on the pressure plate i.e diaphragm spring (Belleville spring) to disengage the clutch plate from the engine shaft flywheel, To perform gear shifting or stoping the vehicle. The default position of the clutch fork is engaged. The weight of the clutch fork system also adds to the overall weight of the vehicle so it is necessary to reduce the weight of the components if possible. Topology optimization can reduce the weight of a component keeping equivalent stresses in check.
