摘    要:本文首次提出可展桁架拟静力展开分析的违约问题。根据受约束动力系统违约稳定与广义逆理论。采用位置违约的最小范数最小二乘解进行主动校正,有效降低位置违约,使展开过程位形模拟更准确。文中四个算例表明该方法正确、可靠。

关 键 词:空间结构  可展桁架  违约稳定  广义逆理论  最小范数  最小二乘解  拟静力展开分析  受约束动力系统  主动校正  位移模拟

Abstract:The position constraint violation problem of quasi-static deployment simulation was firstly proposed for deployable space truss. According to the violation stabilization of constrained dynamical system and generalized inverse theorem, the least norm and least square solution of violations were used to correct the position violation, which reduce violation greatly and make deploying configuration simulation more accurately. The developed algorithm proved the effective and the reliable by a series of numerical results.
Keywords:space structures  deployable truss  deployment analysis  violation stabilization
