Noise analysis design methods and noise analysis designing apparatus

摘要

PROBLEM TO BE SOLVED: To provide simulation technology for finishing multi-physics analysis of heat, vibration, and EMC in an upstream stage of a product design in a practical time by inexpensive calculation processing.;SOLUTION: In a noise analysis design method of an electric device such as an inverter for an automobile, the electric device comprises: one or more energy sources; a propagation path on which energy from the energy source propagates; and a noise occurrence part where an electromagnetic radiation noise occurs due to the energy propagated from the propagation path. The electric device comprises a step for estimating occurrence noise such as occurrence radiation noise by analyzing the path designated by a user by using a computer. The path designated by the user is the path of the energy flowing through the propagation path.;COPYRIGHT: (C)2014,JPO&INPIT
