基于特征的车身覆盖件参数化建模方法研究

研究基于特征的车身覆盖件参数化建模方法。在车身覆盖件建模中引入了特征建模概念，针对车身覆盖件的结构特点及其形状特征的生成机理，提出车身覆盖件形状特征分类方法，归纳体特征控制参数和面特征控制参数。以ＱＣＪ７０８２微型轿车车门内板为例，建立了基于特征的车门内钣参数化模型。应用基于特征的参数化建模方法，可以方便地实现车身覆盖件参数化模型的建立。

The Car Body Panels Parameterized Modeling Method Based on Features

To study the car body panels parameterized modeling method based on features, the concept of features was introduced in modeling for car body panels. The classifying method and control parameters of shape feature for car body panels were presented. The parameterized model for the mini car door internal panel of the QCJ7082 based on its features was constructed. It is obviously convenient to establish the parameterized model for car body panels by using parameterized modeling method based on features.
