DIGITAL SIMULATION OF VIBRATION SOLUTIONS FOR A VEHICLE AUTOMOBILE BODY COMPONENT

摘要

The invention relates to a method for simulating fatigue stresses of a structural element of a motor vehicle body, said element comprising at least one zone supporting a remote mass, the method comprising the following steps: (a) obtaining the spectral power density accelerating the zone or zones supporting a remote mass (10); (b) numerical modeling of the structural element (12); (c) integrating the power spectral density of the area (s) in the numerical modeling (14); (d) calculating constraints as a function of the frequency (16) to identify the limiting stresses (18).
