基于ADAMS和MATLAB的空投火箭联合仿真研究

RESEARCH ON COORDINATED SIMULATION OF AIR-LAUNCHED CARRIER ROCKET BASED ON ADAMS AND MATLAB

为了有效模拟空中发射运载火箭过程和提高其安全性,搭建了空投火箭的虚拟仿真系统。首先在Solidworks中建立运载火箭、载机以及阻力伞的实体模型;然后将其导入动力学仿真软件ADAMS中,并对其进行动力学以及运动学仿真;最后通过MATLAB与ADAMS的接口模块ADAMS/Control,利用MATLAB/Simulink模块搭建火箭的气动数据计算系统以及联合仿真的控制系统,实现基于MATLAB和ADAMS的空投火箭联合仿真。仿真结果验证了该方法建模的正确性和可行性。

To effectively simulate the air-launching process of carrier rocket and improve its safety, we build a virtual simulation system for air-launched rocket. First, a solid model for launch vehicle, eargoplane and parachute is established with Solidworks software; then the model is imported into the dynamic simulation software ADAMS for dynamic and kinematic simulation on it; at last, through the interface modular part （ADAMS/Control） of MATLAB and ADAMS, the aerodynamic data computation system of the rocket and the control system of coordinated simulation are constructed with Simulink module of MATLAB software, thus the coordinated simulation of air-launched carrier rocket based on MATLAb and ADAMS has been implemented. Simulation results verify the correctness and feasibility of the modelling in this way.
