[0041] See figure 1 , shows a flow chart of a method for identifying the sensitivity of a vehicle suspension vibration source provided by the first embodiment of the present invention. The methods include:
[0042] Step S10: Acquiring the excitation force of the powertrain and the vibration simulation data corresponding to the excitation force.
[0043] In step S10, the powertrain (Powerplant) refers to a series of components and components that generate power on the vehicle and transmit power to the road surface, broadly including engine, gearbox, drive shaft, differential, clutch, etc. ; but usually, the powertrain generally refers to the engine, transmission, and other parts integrated into the transmission, such as clutch / front differential, etc. One or more of an engine, an engine crank mechanism, a valve train, a chain system mechanism, a gear train mechanism, etc. may be considered in this embodiment.
[0044] The vibration sources on the engine suspension are comple...
