Abstract

This paper deduces the relationship between the frequency response and loads for a structure within the frequency domain, and puts forward a new method for identifying the random loads spectrum. Firstly, the response power spectrum of structural control points is calculated based on the white noise loads spectrum. Then in order to get the corresponding random loads spectrum, the response power spectrum and the desired output response spectrum are compared. Finally, a specific cabin structure is analyzed by using the above method. The FEA (Finite Element Analysis) simulation results show that the method is valid in identifying the fundamental acceleration loads spectrum.
