Performance Simulation Analysis of Oil-gas Buffer for Lifting Landing Gear
摘要
Abstract
This paper proposes a new type of lifting oil-gas buffer structure which meets both the buffering function and the demands of aircraft loading and unloading cargoes,and the performance parameters of this structure are analyzed through virtual simulation technology.Based on the working principle of this new type of lifting oil-gas buffer,its mathematical model and simulation model are constructed.The results show that,within a certain range,the lifting and buffering performance of this oil-gas buffer is positively correlated with the initial pressure of the air cavity and negatively correlated with the initial volume of the air cavity,however,when the initial pressure of the air cavity increases to 7.5 MPa or the initial volume of the air cavity decreases to 0.01 m3,the system will appear a jitter phenomenon.The results provide a reference for the structural design of oil-gas buffers for lifting landing gear in engineering applications,enhancing both design efficiency and quality.关键词
