The basic idea of the synthetic modal test is to divide the whole structure into several substructures. The modal parameters of the substructures are obtained by means of the modal test for the substructures, and then the parameters are synthesized and the whole structure modal parameters are gained. In automobile NVH analysis, the cost and time-consuming of the modal test for whole white body are usually very high. Using the synthetic modal test method, the cost and time-consuming of the modal test can be reduced, and the precision of the test can still satisfy the engineering requirement.
