Abstract: Multi-powertrain is defined as an engine plus different transmissions, or a transmission plus different engines in this paper. To reduce mount cost and production time, the mounts in a Powertrain Mounting System (PMS) with multi-powertrain should have the same stiffness or the same configurations. On the basis of this requirement, the design strategies and calculation methods for PMS with multi-powertrain are presented in this paper. In designing Multi-PMS (MPMS), an optimisation method to select mount stiffness in its Local Coordinate System (LCS) and locations based on the requirements for six rigid body modes and energy distributions of a PMS with multi-powertrain is developed. Then a procedure of designing Force vs. Displacement (F-D) relation for a mount to control the motion of each powertrain in multi-powertrain is proposed.

Keywords: multi-powertrains; powertrain mounting systems; design strategies; design calculation methods; optimisation; vehicle design; mount stiffness.
