摘要
大下沉速度下全尺寸飞机着陆(舰)的动态性能计算是复杂多体动力学问题。文中结合多体系统动力学理论,利用ADAMS软件的二次开发功能,进行全尺寸飞机着陆(舰)的动态仿真分析,建立全尺寸动态仿真分析模型,模型中考虑多种因素的影响,得出较好的仿真结果,特别是得到飞机重心处的过载系数变化历程。为进一步应用ADAMS软件进行全机动态数值分析提供依据。
The dynamic analysis or computerized simulation of landing impact of cartier-based aircraft with larger sink speed is designed to be a multi-body dynamic system. A dynamic analysis of a multi-body landing impact system for a hill-scale aircraft is presented. This will be incorporated into a simulation of the full-scale cartier-based aircraft drop test. The ideal calculation results especial the time history of the aircraft gravity factor is achieved by taking into account many involved factors. The study offer solutions to digital analysis, dynamic simulation, computer animation and algorithm optimization of cartier-based aircraft landing impact, and then beats the significance of engineering-oriented applications.
