ADAMS用户子程序在软着陆动力学仿真中的应用

软着陆是实施月球表面探测的一项关键技术，为得到月球着陆器的着陆性能，采用ADAMS软件进行动力学仿真。由于着陆器缓冲装置中常采用铝蜂窝结构，且它具有独特的力学特性，仿真时采用了用户子程序，通过在“阿波罗”试验模型中加载子程序实现了系统仿真。最后将仿真结果和相关数据比较，验证了该子程序和建模方法的正确性。

Application of ADAMS User-Written Subroutine to Simulation of Soft-landing Dynamics

Soft - landing was a critical technology for lunar surface exploration. In order to obtain the performance of lunar lander, ADAMS software was used to simulate touchdown dynamics. ADAMS userwritten subroutine was employed because of the unique mechanical property of aluminum honeycomb in impact attenuation of lunar lander. By loading the subroutine on the model of Apollo full scale lunar - module, simulation of the system was realized. The results compared with relevant data confirmed the modeling and application of user- written subroutine of ADAMS.
