摘要
具有倒“Y”型吊挂的降落伞系统在回收领域具有广泛的应用。建立了这类系统的动力学模型,包括考虑附加质量的一般刚体动力学方程和基于“平衡点”假设的吊挂系统建模方法。利用该模型对某型飞船空投试验情况进行了仿真分析,通过与试验数据对比,验证了模型的有效性。
The dynamic model of the parachute system with the inverted ‘Y＇ suspension is established, which is widely used in recovery systems. The model is comprised of the general rigid-body equations considering apparent mass and the modeling method of suspension system based on the assumption of “equilibrium points”. A simulation analysis for a spaceship＇ s airdrop experiment is carried out and the validity of models is showed by the experiment data.
