An Equivalent Model for Modal Analysis of Engine Mounting System

摘要：

　　An equivalent analysis model for engine powertrain mounting system is built with the FEA software ANSYS,in which the engine powertrain is equivalent to a composite body of one inertial body and one elastic body,every mounting component is simplified as one spring along its three principal elastic axes and the powertrain mass and rotational inertia are accurately embodied.With this equivalent model,vibration modes and energy decoupling degrees can be calculated.The result of an example in ANSYS shows that this equivalent modeling method is validity and feasibility for engine powertrain mounting systems.
