Abstract The excitation to a vehicle is from two sources, road excitation and powertrain excitation. Vehicle Suspension is designed to isolate the road excitation coming to passenger cabin. Powertrain mounts play a vital role in isolating the engine excitation. The current study focuses on developing an analytical approach using Low-Fidelity computer programs to design the Powertrain Mount layout and stiffness during the initial stage of product development. Three programs have been developed as a part of this study that satisfy the packaging needs, NVH requirements and static load bearing requirements. The applications are capable of providing the Kinetic Energy Distribution and Static Analysis (Powertrain Enveloping and Mount Durability) for 3-point and 4-point mounting systems and the ideal mount positions and stiffness for 3-point mounting systems.
Abstract Now-a-days there is a trend of engine downsizing driven by emission norms and a race to deliver engine power and torque similar to those which are developed by multi cylinder engines. Thus, engines are running on higher temperatures making the engine cooling system vulnerable. Degassing tank is one of the solutions to resolve the problems pertaining to engine cooling system. The main function of degassing tank, also known as de-aeration tank, hot bottle, expansion tank is to remove the entrapped gases/air from the engine cooling system.
