摘　　要：针对大多数制造企业在产品设计上面临的效率低、周期长、质量难以保证等问题。对参数化CAD和CAE技术,以及软件CAD和CAE之间的数据传输进行了研究,得出一种基于CAD/CAE集成的机械零件性能参数优化的通用设计方法。该方法以Visual Studio为平台,分别使用APDL、C,语言对Ansys、SolidWorks进行二次开发,开发一个基于CAD/CAE集成的机械零件数字化设计系统。改变参数值后系统自动、快速地进行有限元求解,求解结果自动输出到指定路径,并自动打开和锁定求解结果。以从动片内环零件设计为例,运用该方法,快速得到了三维模型和求解结果。研究结果表明,该方法可行,通用性好。Aiming at the problems of low efficiency, long cycle and difficulty in quality assurance in product design faced by most manufacturing enterprises, performing research on parameterized CAD and CAE technology, as well as the data transmission between software CAD and CAE, a general design method for optimizing the performance parameters of mechanical parts based on CAD/CAE integration was proposed. This method took Visual Studio as the platform, used APDL and C;language for redeveloped ANSYS and Solid Works respectively, and developed a digital design system of mechanical parts based on CAD/CAE integration. After changing the parameter value, the system solves the finite element solution automatically and quickly, the solution results are automatically output to the specified path, and the solution results are automatically opened and locked. Taking the design of inner ring of driven plate for example, the three-dimensional(3 D) model and solution results were quickly obtained by this method. The research results show that this method is feasible and universal.
