More Information
Summary:The invention discloses an inverse substructure technology-based transmission path analysis method. The method comprises the steps of 1, sensing and acquiring an excitation signal and a response signal; 2, sensing and acquiring a frequency response function; 3, calculating the dynamic stiffness; 4, calculating the load; 5, calculating the contribution of a transmission path. The method overcomes the defect in the prior art that the test result of dedicated equipment is different from the state of a real vehicle. Therefore, the obtained contribution of the transmission path is enabled to be much closer to the real state of the overall vehicle.
