| Abstract: | A Force-limited vibration testing can alleviate the over-testing phenomenon.Force specification estimation is a prerequisite for a force-limited vibration testing.Basis principle of the complex two-degree-of-freedom system(TDFS) method to estimate the force specification of force-limited vibration test is presented in this paper,and the force specification for the force-limited random vibration test of a spacecraft hardware is derived in detail by using the complex TDFS method. |
