Abstract

Wedged link is widely applied to circular cabin section linking structure for the advantages such as structure reliability, convenient installation and removal as well as high space utilization ratio. Generally, wedge block strength is computed using engineering method. However, the transfer load of wedge block must be obtain firstly, which is usually difficult. The adoption of finite element method makes it possible to simulate the complex load transferring path between wedge block and cabin body, thus obtaining a more comprehensive integral structural stress distribution. Nevertheless, the computation convergence is not satisfactory due to a number of contact surfaces. On the basis of ANSYS Parameter Design Language (APDL), the full contact analysis command stream of wedged link structure for typical circular cabin section is developed to carry out the detailed designs for structural size, tolerance fit clearance and pre-stress. A new structure form is obtained based on the contact analysis, which is more reliable for connecting and easy for manufacturing.
