    摘要:

    基于SolidWorks軟件和ABAQUS有限元分析軟件平臺，提出了一種機床結構CAD/CAE集成分析方法,，綜合應用CAD參數(shù)化建模功能和CAE分析功能,，實現(xiàn)了CAD/CAE集成和自動計算,；以提高機床結構性能建模效率為目的,，提出了一種基于拉丁超立方抽樣試驗設計和CAD/CAE集成分析的逐步回歸建模方法,，該方法通過監(jiān)測建模過程中回歸模型的精度,，在保證建模精度的前提下,，減少試驗樣本數(shù)量,。以弧齒錐齒輪銑齒機為例,，實現(xiàn)了該機床結構的CAD/CAE集成分析和機床結構優(yōu)化逐步回歸建模，驗證了提出的分析及建模方法的可行性,。

    Abstract:

    A CAD/CAE integration analytical method of machine tool mechanism was proposed based on the 3-D design software SolidWorks and the finite element analysis software ABAQUS, the CAD/CAE integration and automatic computation were realized by integrating the parametric modeling function of CAD and the finite element analysis function of CAE. Stepwise regression modeling based on Latin hypercube sampling and CAD/CAE integration was also proposed to improve the modeling efficiency of machine tool structural performance, it could reduce the samples and ensure the modeling accuracy by monitoring the stepwise regression model. The CAD/CAE integration analysis and stepwise regression model were carried out on spiral bevel gear milling machine, and proved to be feasible. 
