载人运载器搭载对接装置缓冲性能优化

Cushioning performance optimization of carrying and docking device for manned carrier

针对小型载人运载器水下对接、搭载和投送的任务需求,设计了背驮式小型运载器搭载对接装置.选取对接过程总冲量为目标变量,基于响应面方法和Central Composite Design(中心组合设计)试验设计方法,分别建立了多种对接情况下目标变量碰撞冲量关于初始对接参数的数学模型.利用Adams软件建立虚拟样机并获得试验数据,求解各模型对接冲量最大的情况和对应的对接参数.基于Abaqus有限元软件,引入缓冲杆参数作为设计变量,根据确定的对接参数建立目标函数关于缓冲杆参数的数学模型,最终得到最优的缓冲杆参数,降低了对接过程中运载器对母平台的冲击.

A small carrier piggyback-mounted docking device was designed to meet the demands of the task of underwater docking,loading and delivery of small manned carrier.By selecting the total impulse of the docking process as the target variable,a mathematical model of the initial impact parameters of the target variable collision impulses under various docking conditions was established based on the response surface method and the Central Composite Design experimental design method.Virtual prototype was built and experimental data were obtained by using Adams software,and the model was solved to get the maximum amount of docking impulse and the corresponding docking parameters.Based on Abaqus finite element software,the buffer rod parameters were introduced as design variables.According to the determined docking parameters,the mathematical model of the objective function with respect to the buffer rod parameters was established,and finally the optimal buffer rod parameters were obtained,which could reduce the impact of the carrier on the mother platform during the docking process.
