The methods of Computer-Aided parameterized design and Computer-Aided Engineering analysis are used to build a reasonable parameterized geometric model for key components (for example: Transmission Shaft、Universal Joint、bearing and so on). Then a parametric-related function conforming to the demand of intensity from the conditions of forces act on Vertical Axis Wind Turbine in working and boundary settings for the basis of modeling created by parameterized design is concluded. At first, the theories of strength intensity and experienced data of key components are studied, then dynamic analysis and stress estimating of the Vertical Axis Wind Turbine set and parts are preceded. The results of analysis are verified to the parameterized design, the benefit and functions of the system. Next, Autodesk Inventor software is used to build 3D models by the parameterized-design function module, and ANSYS Workbench is used to analyze stresses of parts and combined parts in the Vertical Axis Wind Turbine. Then Taguchi Method is applied to find out the reasonable designing parameters. The purpose of this study is to analyze and conclude the specifications of parts, then build a database that will supply bases or references for model mechanics or key components selecting when design a Vertical Axis Wind Turbine or any related study.To take the roller thrust bearing、the upper case and main bearing of the assebmble condition by simulation analysis, the beneficial result to test and verify is efficacious.
