Abstract:

In view of the micro manufacturing platform, the problem of isolation based on Udwadia-Kalaba theory to establish the dynamics model of vibration isolation platform, and study its dynamic characteristics under pedestrian excitation. The dynamic model of Udwadia - Kalaba was established for the two structures, and the various particle response curves of solid and dispersed structure were obtained by Matlab simulation. The result of research shows that a dynamic model based on the Udwadia - Kalaba theory can be solved without introducing Lagrange multipliers;Solid structure and decentralized structure even the response curve of the contrast, it is known that the solid even structure relative to the dispersed structure model can achieve good damping effect, and the theoretical method can better applied to the micro vibration isolation platform vibration dynamics to solve the manufacturing aspect.
