Dynamic Analysis Of Rotary Platform Transmission System In Roll Collecting Station Based On Virtual Prototyping Technique

With the development of iron and steel industry, the mechanical equipments are now going towards to lightweight high-speed and high-accuracy, thus deformation more widely exit in the mechanical equipment. The design of transmission part which is the essential componend of mechanical equipment is curcial to the mechanical equipment's running precision. Especially, the deformation of mechanical part can affect the work's performance and the running accuracy of the transmission system, and even greatly impact the performance of the whole mechanical equipment. In the traditional design stage, because of lack consideration of the deformation of the compond of the mechanical equipment, it also greatly impacts the design of other relevant systems. So the traditonal design method can't meet the requirement.Introducing the virtual prototype technology to the dynamic analysis of transmission system can realize emulational simulation of mechanical equipment under pratical condition using computer technology. In additional simulation of the deformation of the mechanical part uses rigid-flexible coupling system. According the simulation output parameters and results to estimate and infer the actual operational datas. This method has certain reference value to the dynamic analysis and structure design of mechanical transimission system.This article based on rotary platform transmission system in roll collecting station of high-speed steel wire in one steel factory. The main research contents are listed below:(1)According to the drawings and the testing datas analysis the structure,motion and dynamic of rotary platform transimission system.(2)Using parametric modelling method in Pro/E establish three dimensional model of transimission system.(3)Intrducing the three dimensional model to ADAMS, then establish the virtual prototype of rotary platform transmission system.By means of the output datas include angular velocities and gear meshing forces to verify the correctness of the established virtual prototype system. Simulating the actual operation situation of the system, then analys the output curves of angular velocities and angular displacement.(4)Utilizing Pro/E and ANSYS establish the flexibility of the low speed shaft, then introducing the model neutral file to ADAMS. So the rigid-flexible coupled virtual prototype system is established. Simulating the model and comparative analys the output curves of angular velocities and angular displacement with the output curves under rigid shaft. Analysing the output stress map in ADAMS, then import the load file to ANSYS in order to carry out stress analysis. Comparative analysising the results of the stress analysis to verify the correctness of the model neutral file and the result of the stress analysis in ADAMS. This method provides evidence for the application for virtual protype technology in rotary platform transimission system.The research of this article introduce the method that contains: establish model in Pro/E, dynamic analys of the virtual protype which include the flexible part and stress analysis of the flexible part using ADAMS and ANSYS.By means of the interfaces between the software to another, make full use of the advantages of CAD software and the CAE softwares. This method improves the precision of design and analysis.
