Based On Virtual Prototyping Technology Double Helix Vice Rotating Cylinder Structure Parameters Design And Optimization

As one of hydraulic devices in common use, Rotating hydraulic cylinder can translate linear motion of the piston into rotary movement and do work, it has been widely used in all walks of life, there are different requirements of the structure form and performance for different application situations, it is difficult to achieve optimal design of rotating hydraulic cylinder by using traditional design method, for in the traditional design, the designer primarily on the basis of past design experience, combined with a large number of empirical formula and the design parameters for the specific design. This paper applies the Virtual Prototyping Technology to design the rotating hydraulic cylinder for solving the issues in the traditional design, which is longer design cycle and higher cost.Based on the Virtual Prototyping Technology, In this paper studies the optimal design of the rotating hydraulic cylinder. With the CAD/ CAE/CAM feature-based modeling tool of the Pro/E(Pro/ENGINEER), mechanical dynamics simulation software, ADAMS (Automatic Dynamic Analysis Mechanical System) and the finite element software of ANSYS. First of all, the three-dimensional model of the rotating hydraulic cylinder is built up and accomplished its virtual assembling with the software of Pro/E, validating the correctness of the model by doing kinematics analysis. The multibody dynamics model of 360-degrees of double screw pair of rotating hydraulic cylinder is built up by Utilizing the ADAMS software and make a research, the result of simulation is similar with calculation in the theory. Verify the correctness of the virtual prototype. Study the output screw rotation and bearing load characteristics with different Toothed-shaped angle. based the boundary condition, the FEA static analysis of the key parts of the rotating hydraulic cylinder, is made with the FEA software-ANSYS. These analysis provide the theory for the structural design and optimization. In the end, the rotating hydraulic cylinder experiment is carried out for verifying the correctness of design and reaching the design goal. The method and theory used in this paper can also be used in other products design and research.
