首先介绍了参数化的发展及技术现状,然后分别介绍了零件参数化和部件参数化的基本方法,零件参数化主要是尺寸驱动和程序驱动两种方法,部件参数化主要是自顶向下和自底向上两种设计方法,并且介绍了各种方法的优缺点,为机械压力机参数化设计打下理论基础。 Firstly, the development of parametrization and the status quo of technology are introduced. Then, the basic methods of parameterizing parts and parameterizing parts are introduced respectively. Part parameterization is mainly driven by dimension and program driven. The parameterization of components is mainly from top to bottom and Bottom-up two design methods, and introduced the advantages and disadvantages of various methods, laid the theoretical foundation for the mechanical press parametric design.
