On the road surface which is not even noise of the vehicle which travels/the method where it estimates decides comfortable efficiency

摘要

This invention travels noise of the crew-member interior of the vehicle which possesses the road surface connected system which is connected to the body the body and at least depending upon one installation place/being the method where it estimates decides comfortable efficiency, with respect to the travelling medium which has the travelling aspect where the vehicle is rough in broad perspective at speed of given, while step and the step which seeks the admittance of the body and seeks the impedance of the road surface connected system the step which calculate the global transfer function of the body in method, and, on in broad perspective rough road surface travelling global transfer function of step and the body which calculate the stopping power of the road surface connected system, the bodyNoise of the crew-member interior/comfortable efficiency (P) it regards the method of featuring that it possesses the step which obtains estimate global admittance, combining the impedance of the road surface connected system and the stopping stress of the road surface connected system with each other.
