The Impact of Assembly on the Results of Modal Analysis

Abstract:

The influence of the state of assembly and entity on modal simulation data in the computer simulation is different. In this paper, a typical modal analysis of hydraulic manipulator with the finite element method is conducted to discuss the different. The assembly is assembled by Boolean operations to makes surfaces merging together directly and then converted into the solid model. This way can ensure the validity of the comparable data. The conclusion shows that properly setting the assembly model can make the simulation results closer to the actual working conditions in the computer simulation by comparing the modal simulation data.
