起落架用于飞机的起降滑跑、地面滑行和在地面停放时减缓撞击。伴随21世纪世界各国航空技术水平的发展,飞行器种类和工作环境日益多样化,起落环境也越来越复杂。在这样的条件下,对飞机起落装置性能提出了更新更严苛的要求。在起落架试验方面,试验成本高,装置复杂,难以完全模拟真实环境,且试验装置重复利用率低。机械系统的虚拟样机技术即机械系统动态仿真技术,是一项伴随计算机技术发展起来的新技术。借助这项技术,可以模拟现实环 Landing gear for aircraft take-off and landing run, ground taxiing and slowing down when parked on the ground impact. With the development of aviation technology in various countries of the world in the 21st century, aircraft types and working environments are increasingly diversified, and the landing environment is becoming more and more complicated. Under such conditions, newer and more stringent requirements for aircraft landing gear performance are proposed. In the landing gear test, the test cost is high, the device is complex, it is difficult to completely simulate the real environment, and the test device has low repetition rate. Mechanical system of virtual prototype technology that is dynamic mechanical system simulation technology is a new technology accompanied by the development of computer technology. With this technology, you can simulate the real world
