Numerical and Experimental Study on Air Cushion System Dynamics for Semi-Track Air-cushion Vehicle

摘要

In this paper,the method of studying the air cushion system dynamics for semi-track air-cushion vehicle (STACV) was proposed.First,The paper introduced the air cushion system lift force generate problem in the semi-track air-cushion vehicle.Then,according to the typical air cushion force change process,an experiment was designed to better understand the process and provide the contrasting data for the numerical simulations.After that,a series of 3D computational fluid dynamics simulations were carried out to find the equivalent clearance height of the prototype.The simulation results also revealed some inner characteristics of the air cushion system on the STACV.It was proved to be an efficient and accurate method and can be used to predict the performance of the air cushion system of the STACV.
