The finite element model of worktable system is created and modal analysis is made with ANSYS Workbench by taking DVG850 high-speed vertical machining center worktable system for example. We make modal analysis of single-screw strength general reinforcement worktable system and get the natural frequency and the vibration mode.Then in order to improve the system's natural frequency, the scheme of dual-screw worktable system is put forward. Also natural frequency and vibration mode is got. Finally, it is proved that the performance of dual-screw worktable system is significantly better than the single-screw one. This provides a reliable reference for further study on dynamic analysis of worktable system.

According to the structure and characteristics of the HSK-A63 tool holder, we design and retrofit the non-standard tool holder with special function module. Establish and assemble three-dimensional entity models of embedded temperature measuring tool holder, ER collet/nut and flat end mill with Pro/E 5.0. Based on the establishment of the reasonable boundary conditions and meshing of the tool holder assembly, natural frequency and vibration modes of the tool holder assembly are calculated by modal analysis with the Ansys Workbench. These analysis results are the important research basis for the dynamic characteristics designing and dynamic balance researching to the tool system.

CNC lathe spindle box is a key component of the CNC lathe system, and its dynamic characteristics are the main factor affecting the machining accuracy and processing efficiency of machine tools. In this paper, CK61125 CNC lathe spindle box model was established by simplifying its structure. Then modal analysis of the spindle box was done and extended to 6-order modes with the platform of co-simulation environment in ANSYS Workbench, and the natural frequencies and vibration modes for lathe spindle box were obtained. The weak links in the spindle box were found, and the improvement schemes are proposed. Finally the lathe spindle box was improved, the modal analysis of the spindle box was made again, and the results showed that the lathe spindle box dynamic performance was improved. All of these results are beneficial for optimization and re-design of the lathe spindle box so that it has better dynamic performance.

As the less-teeth gear has the less-teeth, the bigger helix angle and the more contact ratio etc. The research of dynamic meshing characteristics makes focus, and modal analysis is the basis of dynamic analysis. In order to get the modal analysis characteristics: firstly the parametric solid modeling is realized through the software of MATLAB and PRO/E; secondly multistage inherent frequencies and mode shapes are achieved by the finite element software of ANSYS Workbench.

The heavy-load manipulator arm, an important part of the remote handling maintenance system of the large-scale multi-purpose deployer, plays a key role of the entire system. Its modeling and assembly was finished by Pro/E. Then use the ANSYS Workbench, finite element analysis software, to complete its static analysis and modal analysis through building a seamless connection between Pro/E and ANSYS Workbench. As a result, the overall deformation and static stiffness values of the manipulator arm were obtained through static analysis, and the former six-order natural frequency values and mode shapes were obtained through modal analysis. Finally, scheme of structure modification and new control method were presented by analyzing and comparing the results.

Alloy wheels in the motor cycle play major role to carry the load over the spoke wheels. The shape and orientation of the spokes are responsible for withstand the loads which are acting on the alloy wheel rim and hub bearing surface. These alloy wheel spokes are subjected to different types of loads i.e., radial loads, impact load, bending load, torsion load and maximum deflection load. So it is necessary to study the response of the wheel under these types of loads before the product going into the market. In the present article 4 models of motor cycle alloy wheel are modeled based on the dimensions in the reference article. The material chosen for the analysis of the alloy wheel is aluminum alloy which is homogenous in nature having isotropic properties. The magnitude of the five different loading conditions and boundary conditions are taken from the Automotive Industry Standards (AIS). The four models of alloy wheels are analyzed under radial, impact, bending, torsion and maximum deflection loads cases by using by using ANSYS workbench. The results show that all four models are having enough fatigue life, strength and stiffness against the different loading conditions.
