Abstract:

A flat plane Crankshaft has significant secondary in balance ( like a 4 cylinder ) which cause the engine to vibrate which can start shaking the car to pieces. A cross plane crankshaft has good balance and the vibrations are much smaller, which may give it an advantage in long distance sports car racing. Cross plane crank shaft is employed recently in Mercedes Benz, Yamaha..In this study, an attempt is made to do dynamic analysis on the cross plane crankshaft in Ansys to study its behavior under dynamic loading. The results from the dynamic analysis of the cross plane crankshaft are compared with the flat plane crankshaft. The knowledge about the cross plane crank shaft and its advantage and disadvantage over the normal flat plane crank shaft is the first step towards the of the cross plane shaft that could be achieved with the help of literatures related to the this topic. The modeling of the cross plane crank shaft will be done in Ansys. The time dependent load acting on the crank shaft is to be calculated from the concept of Dynamics which is very essential in carrying out the dynamic analysis in Ansys. From the results of the dynamic analysis, the strength and rigidity of the crank shaft is explained and compared with the flat plane crank shaft.
