Damping Characteristics Simulation and Test Research of Vane Damp

Abstract:

A new hydraulic model based on the structure analysis of the vane damp was established , which can be given the damping parameters directly. Based on damping force and velocity input test data, the parameters about the hydraulic model are identified by least squares fitting method,which is using to study the damping characteristics .Each parameter has its own physics meaning not only the math way, but also the physical influence. The method can be reduced the vane damp process and fix error. In the different temperature, comparison of the test data and results of calculation with the fitting parameters shows that the parameters are correct and the method is valid. Vane damp design and character analysis can be supported and the damping characteristics simulation method can be extended.
