缓冲器是所有现代飞机起落架必备的通用部件,其性能直接影响起落架的承载能力、质量、寿命、地面操纵安全性和乘员舒适性等。缓冲的实质就是把飞机的动能消散在缓冲系统(轮胎和缓冲器)和飞机及起落架结构的变形上~([1-2])。LMS Virtual.Lab Motion基于计算多体系统动力学建模理论及计算方法研究,是专门为模拟机械系统的真实运动和载荷而设计的~([3])。LMS Imagine.Lab AMESim为
The shock absorber is a must-have universal part for all modern aircraft landing gear and its performance directly affects the load-bearing capacity, quality, longevity, ground handling safety and occupant comfort of the undercarriage. The essence of cushioning is to dissipate the kinetic energy of the aircraft over the deformation of the cushioning system (tires and bumpers) and aircraft and landing gear structures ([1-2]). LMS Virtual.Lab Motion is based on computational multi-body system dynamics modeling theory and computational methods and is designed to simulate the real motion and load of mechanical systems.
