Parametric design of turbodrill bearing section based on VB and Solidworks

The basic structure of turbodrill is analyzed and the necessity of parametric design is presented. Being compared with the other methods of Solidworks parameter design, the dimension-driven method is chosen to develop a parametric program which can automatically create a series of models with different dimensions. Draft of bearing section assembly of turbodrill is built to create models of each part, which is an effective way to link the dimensions of each model. The process of parametric design and cooperative design of turbodrill is studied. The parametric program is developed and the main interface as well as each form are built.
