| Abstract: | By using partial coherence function and correlation analysis, the input
contribution to output for multi-input and output liner system is quanticative and qualitative discriminated when the input is correlation cases. The conclusion is extended into automobile ride comfort. In the paper, the wheels input contribution to vibration output of the every seat is discriminated and the ride comfort is improved by reducing the wheel' s stiffness. |
