摘要
Abstract
The sloshing characteristics of a type of large volume tank affect the whole system dynamic characteristics and orbit control system directly.In order to get the free sloshing frequency of the tank under different working conditions,a new method of tank liquid sloshing test based on air cushion flotation technology is proposed.A set of experiment system,including tank,excitation system,air flotation control system,data acquisition system and filling & draining system,is designed by this method to solve the liquid sloshing problem under different working conditions.The final simulation results were achieved by Fourier transform and time domain simulation analysis results obtained by CFD software.The results indicate that the test result,theory result and the CFD simulation result are consistent,and prove that the test system is reliable and the simulation results of CFD are correct.The test results provide an important reference and supporting data for tank design optimization and launch vehicle attitude & orbit control system design optimization.关键词
