Dimensional optimization of clutch disc with simulation of stress analysis

The function of clutch disc is to transmit the power from the engine to the transmission. There are a lot of vehicle that equipped with different size of engine capacity. Therefore, it is required to use a clutch disc with the appropriate capability to transmit the power from the engine. Note that there is a clutch disc modification type that combine the Japanese and European design called clutch disc Hino MB. This type clutch disc is used for Hino FM 260Ti. By using the combination design, the clutch disc will have longer lifetime and lower risk to crack. There is a crack problem that happened from the usage of clutch disc Hino MB. Therefore, it is necessary to do a research to optimize the design of clutch disc Hino MB. This research is done by making several new designs of clutch disc Hino MB and tests it through simulation of stress analysis. The parameter that had been analysed is the value of von mises stress from each design. The length of grooves is also analysed to get a better design result. This research produces a new design of clutch disc Hino MB that has better design structure. The best result of the simulation that has been done to the clutch disc with interval 5 mm reduction is owned by clutch disc with 35 mm groove�s length reduction and the value is 121.1 MP
