Abstract
The dynamic characteristics of the fixture directly affect the measurement in the vibration test of torpedo cabin.In this paper, theoretical analysis and numerical calculations of dynamic characteristics are carried out for three design schemes of fixture for torpedo cabin vibration test.The natural frequencies, vibration modes and vibration responses of the three fixture designs are calculated numerically, their dynamic performances are compared and analyzed to finally determine the right fixture, which can meet the transitivity requirement of vibration test of torpedo cabin.Conclusions are drawn as follows:1) the stiffness, natural frequency and damping of these fixtures have the most prominent influences on their vibration transfer characteristics;2) the monoblock cast fixture is better in the transitivity than the welded or the bolt-connected one;3) the fixture designed on the basis of dynamic characteristics can better ensure the transmission of vibration energy without distortion.关键词
