- Abstract
Modal test is one of the basic works of studying on dynamic characteristics of aircraft. The ideal state is to make the specimen in the “free-free” state when doing modal test. In actual, specimen is supported by an elastic supporting system, the stiffness, added mass and supporting position of the supporting system will affect the rigid-body modal frequency of the system directly. In this paper, we took a certain aerospace products as an example and used ANSA, NASTRAN software, studied on the influence of stiffness, added mass and supporting position of the supporting system on modal test results, and put forward the design method of modal test supporting system.
