某型灭火飞机水箱晃动结构动响应分析
摘要
Abstract
In the working process of fire-fighting aircraft,the sloshing of fire-extinguishing agent will have an impact on the structure of water tank and affect the flight stability.In order to solve this problem,taking the water tank of a fire extinguishing aircraft as the research object,the fluid-structure coupling simulation model of FEM-SPH is established based on LS-DYNA,and the simulation analysis of water tank fire extinguishing agent sloshing is carried out.The dynamic response of the water tank structure,the change of the liquid center of gravity and the inhibition of the anti-sloshing plate during the take-off stage of the aircraft are studied in order to provide effective calculation and analysis data and optimization suggestions for the basic water tank design of the integrated avionics fire extinguishing platform of this type of aircraft.关键词
