Abstract: In order to analyze vibration characteristics of whole structure of the spherical grinder, the finite element analysis software is applied to finite element modal analysis of the structure. 3D model of spherical grinder is established by Pro/ENGINEER software. Finite element model of spherical grinder is established in the finite element analysis software ANSYS Workbench. The previous 6-order inherent frequencies and the corresponding vibration modes are obtained through the finite element calculation. According to the vibration intensity distribution, the corresponding improvement measure is put forward. It provides theoretical basis for dynamic analysis and improved design of spherical grinder.

Abstract: Taking a large vertical machining center spindle box as research object, its three-dimensional model is established by using Pro/ENGINEER software. Due to the seamless integration between ANSYS Workbench and Pro/ENGINEER, ANSYS Workbench is used to structural analysis of static and dynamic characteristics of spindle box. It has been achieved which includes static stress, deformation, inherent frequencies and vibration mode. Based on the analysis results, improvement scheme for spindle box structure has been proposed and validated. This study provides theoretical basis for design and improvement of machining center spindle box.

Abstract: When the common cylindrical helical spring is used in high-frequency vibration sieve for slime dewatering, there are many problems such as poor vibration resistance, easy happening fatigue fracture, etc. In order to solve these problems, this paper uses the stranded wire helical spring as a support instead, and applies fuzzy theory method to get the optimization design. By selecting the design variables correlated with spring and determining the objective function together with the constraint conditions, the fuzzy optimization mathematical model is built and the optimum solution is obtained so as to achieve the perfect results of optimization.
