Abstract在弹簧作为航天任务中有效载荷的推进装置的优化设计中,为保证载荷的释放速度以及弹簧质量最轻,结合几何约束、可靠性与稳定性的要求,建立非线性约束优化模型,将Matlab求得的理论解带人商业软件Adams进行仿真运算,得到理论速度与仿真速度的拟合关系。利用拟合关系和用Matlab优化工具箱即可求得满足仿真分离速度的弹簧设计参数。利用上述方法对分离推力弹簧进行设计与计算,并利用虚拟样机技术进行验证,减少了弹簧设计重复试算的过程,弹簧质量缩减率在30%以上,满足释放速度要求,得到满意的优化设计结果。
Other AbstractSprings can be used to provide release rate for payload in space missions. In order to guarantee the precise releasing velocity of payload and the minimum mass of springs,a nonlinear constrained optimization model was built with geometric constraints, reliability and stability. The theory solution of MATLAB was brought into Adams for simulation, which can work out the fitting relationship between theory and simulation. The spring design parameters were obtained by using the fitting relationship and calculation of MATLAB. The result was verified by Virtual Prototype Technology and perfect performance of design parameters was achieved.
