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.

This paper provides static, modal and dynamic analysis of the assembly consisting of fixing clamp, inductive sensor, two fixing bolts and frame applied on railway stock. All the necessary tests to perform this analysis are in accordance with the standard EN 61373: 2010 or the Slovak standard STN EN 61373: 2011. In the next part, a simulation of the tests required for the dynamic analysis of the modelled assembly is performed. For each analysis, von Misses stress is evaluated and then compared to the yield strength of used material. Finally, this work provides a proposal for new design solutions of the fixing clamp based on the obtained results. All analyses were performed in ANSYS Workbench programme using finite element method.

In this paper, a methodology is presented to perform dynamic analysis of structural linked mechanisms under true actuation cycle and force response of applied IPMC actuators. Dynamic analysis of a three link mechanism for fin actuation of a micro fish like device, towed by a surface vessel through tow cable, is performed through this methodology and same is applicable to other biomimetic robotic applications. Fluid (water) exerts a torque on IPMC actuated fin which is a function of fin's deflection and fluid flow velocity. Dynamic analysis is performed to assess the performance and efficacy of fin actuation mechanism under different loading conditions in terms of fin's deflection, velocity and acceleration. Actuation force is increased by increasing number of applied IPMC actuators of known actuation cycle and force generation response. Applied torque is determined by performing a numerical simulation of IPMC actuated fin against different flow velocities through two-way fluid structure interaction (FSI) approach. Numerical simulation is performed in ANSYS WORKBENCH to capture the complex hydrodynamic interactions between fin and fluid. Effect of increased actuation force against constant flow velocity (towing speed) and of increased flow velocity against constant actuation force are evaluated in terms of fin's deflection, velocity and acceleration. Finally, consequence of increasing the length of the link, connecting IPMC actuators and fin, are appraised for same actuation force and applied torque. Dynamic analysis is performed in Pro/ Mechanism, an advanced simulation tool. A technique of virtual prototyping through simulations is applied to access the performance of the fin actuation mechanism under true loading scenario before going into experimental phase, saving cost and time

In traditional single-screw worktable system, the system is always subjected with torque because the driving force and force-bearing point of the workpiece always change with the processing path, so its performance may be affected. Therefore, the scheme of dual-screw worktable system is put forward and modal analysis with ANSYS Workbench is made by taking DVG850 high-speed vertical machining center worktable system for example. Then four alternatives of the machine are proposed based on the position of screw and guide.Through modal analysis of different parameters of the system, we ultimately select the dual-screw worktable system with highest performance (Screws place inside of the guide and horizontal distance of the two screws is 310mm.) as the optimalizing plan. This provides a reliable reference for further study on dynamic analysis of worktable system.

The main structure of DVG850 high-speed vertical machining center is instructed in the paper, the solid 3D model of the machine is established by SolidWorks, and then improted into ANSYS Workbench to do static and dynamic analysis. Firstly, the static analysis of high-speed vertical machining center is studied to get the deformation figures. From the analysis of the deformation figures, we can find the locations of weak static stiffness. Next, the modal analysis is studied and the order of natural frequencies we need are obtained. Through the analysis of the vibration modes of this machine tools, its relative weaker parts are pointed. Finally, The structure of the machine tools is improved according to the analysis results. The static and dynamic characteristics of the improved structure are apparently better than that of the original design. It makes a base for optimized design and remanufacturing. .

This paper concerns the design and analysis of a 6-DOF inverted Stewart platform of an amusement park. In consideration of both the thrill-seeking and the safety of tourists, the platform must have 3 proper translational axial accelerations and 3 proper rotary angular accelerations within one motion cycle, and the impact of seismic force shall be taken into account in order to retain the adaptability to change of the system in case of emergent situations. Besides, the safety factors of various parts and components of the system shall be higher than six. In this paper, a 3D model is developed for the platform by means of Solidwork, and kinematics simulation is carried out by means of Cosmos/Motion software to generate 3D geometrical diagrams which are to be transferred into ANSYS Workbench software, and at last, the optimized design of geometry of each part/component of the system and the evaluation of overall safety of the system are conducted in Workbench software based on foresaid 3D geometrical diagrams.
