飞机的起飞和着陆是飞机事故的多发阶段,大量统计表明:有一半以上的安全事故发生在飞机起飞着陆阶段,这就要求起落架系统具有极其高的安全特性。起落架作为飞机安全飞行的关键部件,其受力情况复杂、工作环境恶劣、故障率高。结构强度作为起落架性能的主要影响因素,一直受到设计人员的重视。本课题以直升机半摇臂式起落架作为研究对象,将工作重心放在起落装置的结构强度虚拟试验上。通过LMS Virtual lab、nCode及Nastran
Plane take-off and landing are multiple stages of aircraft accidents, a large number of statistics show that: more than half of the accidents occurred during the take-off and landing phase of the aircraft, which requires the landing gear system has extremely high safety features. Landing gear as a safe flight aircraft key components, the force situation is complex, poor working conditions, high failure rate. Structural strength as a landing gear performance of the main factors that have been designers of attention. The subject of helicopter semi-rocker landing gear as the research object, the focus of work on the landing gear structure strength virtual test. With LMS Virtual lab, nCode and Nastran
