The Study of Configuration Optimization for Air Cushion Vehicle Skirt Based on CATIA-Abaqus Parametric Finite Element Method

摘要

A parametric-driven finite element method based on the application development of CATIA and Abaqus for optimizing the skirt configuration was presented, in which the dynamic explicit solving method is applied. The configuration experiments were also conducted to demonstrate the validation of the method. The effect of geometry parameters, such as length ratio between the inner and outer bag, anti-bounce web size, on the configuration and responsiveness of skirt were investigated. The configuration of bow-side corner skirt optimized by the parametric-driven finite element method has a uniform skirt height distribution which is beneficial to the overall performance of air cushion vehicle.
