Dynamic Performance Analysis

The use of finite element theory and modal analysis theory, the structure of the machine static and dynamic performance analysis and prediction using optimal design method for optimization, the new machine to improve job performance, improve processing accuracy, shorten the development cycle and enhance the competitiveness of products is very important. Selected for three-dimensional CAD modeling software-UG NX4.0 and finite element analysis software-ANSYS to set up the structure of the beam finite element model, and then post on the overall structure of the static and dynamic characteristic analysis, on the basis of optimized static and dynamic performance is more superior double wall structure of the beam. And by changing the wall thickness and the thickness of the inner wall, as well as the reinforcement plate thickness overall sensitivity analysis shows that changes in these three parameters on the dynamic characteristics of post impact. Application of topology optimization methods, determine the optimal structure of the beam ultimately.

Abstract This paper describes an optimal design method for a damping structure using constrained viscoelastic material. The relationship between viscoelastic material behavior and the damping effect, is analyzed by finite element method, where viscoelastic material is modeled by discrete spring elements with the equivalent stiffness and loss factor. This finite element model is applied to the design of a head-gimbal-assembly (HGA) of a magnetic disk device and its reliability is confirmed experimentally. The analysis shows that the maximum deformation of the constrained viscoelastic material occurs at the edge area, so to optimize the damping structure, this area should be placed on the area of high strain energy. Although the damping effect by constrained viscoelastic material has been considered due to shear deformation of viscoelastic material, in this analysis, tensile deformation of the egde of viscoelastic material is strongly related to the damping effect for the bending and torsional modes of HGA. Therefore, an accurate analysis must consider tensile deformation of viscoelastic material.
