This paper is concerned with the replacement of automobile metal part with plastic part. Here the metal triple tree of motorcycle has been replaced with plastic triple tree. In this project the existing triple tree of motorcycle has been analysed and the new model has been designed using integrated analysis. The new design modelling and analysis is done on integral triple tree which have only one connecting component for clamping handlebar, other parts are integrated to achieve better mechanical reliability and performance of new model. Understanding of stress affected region in triple tree and proper analysis of the dynamic loading allow for more rapid and effective part design. A detailed design procedure is presented to optimize the torque and loads acting on this element. The dimensions of model have been optimized to achieve maximum allowable stress. The forces and steering torque have been analysed. Simulations and experimental tests are carried out in order to validate the performance of new model. The durability and performance of new designed model is parallel to the metal and alloys triple tree currently used in motorcycles.
