Abstract:

According to the characteristics of two kinds of skeleton model， through the publish geometry and copy geometry, the static skeleton model can be changed into motion skeleton model, which can define the shape of each component part of support , optimize the support mechanism and motion simulation. By using the related parameters measured directly in Pro/E, inputing the calculation formula in the dialog box, main mechanics can be calculated. Application shows that, the top-down method which using skeleton model meets requirements and represents the design direction in the future.

Key words: powered support, top-down, Skeleton model, Mechanical parameters, motion simulation
