| 520 | |a Modern cars are equipped with continuously variable transmission (CVT) to make the vehicle smooth operation and to reduce the transmission losses. Many researchers and car companies have developed several types of CVT to improve the transmission losses with maintaining the acceleration time. However, most of the studies reported that the developed CVT has some constrains in the actuation mechanism which leads this study to develop an innovative electromagnetic actuator (EMA) for continuously variable transmission (CVT) system application. The simplified mathematical equations have been developed for the kinematics analysis of clamping and electromagnetic forces of EMA. The EMA of this study has been developed for ¼ scale car with two sets of solenoid. Each set of the solenoids has been equipped with primary and secondary pulleys for pushing and pulling the movable sheave. The operation of the solenoid is performed by controlling the supply current with a potentiometer. A simulation based Fuzzy Logic controller has also been introduced in this study to predict the EMA system dynamic behaviour for identifying the current control of the EMA actuation. The fuzzy simulation block embedded with a mathematical function assists to predict system responses. The EMA experiment has been conducted by controlling the currents that were identified from the fuzzy simulation. The EMA developed electromagnetic forces of 108 N for a current of 1.21 amp and 301 N for a current of 3.37 amp which are good enough to overcome the clamping force for the ¼ scale car with a maximum force of 278 N. It is observed that travelling time of the plunger is within the range of 1.8– 3.1sec which could be considered as the acceleration time for the car. The correlations between the measured and predicted values of traction torque have been found for 90.99%. It indicates that the predicted data over the measured data have a closed agreement and thus, substantially verified the fuzzy simulation model. | ||
