摘要
从作动器作动力阀值和作动器间刚度耦合影响角度出发,建立了可重构反射器计算模型,对微步长位移法计算流程进行了改进,并通过仿真试验对改进后的算法进行了验证,最后对仿真结果进行了分析。仿真结果表明,改进后的微步长位移法可满足各作动器最大作动力小于作动器作动力阀值,重构后反射器形面精度保持不变。
Viewed from the influence of the threshold level of actuators and the coupling between the actuators＇ stiffness,the FEM analytical model of the reconfigurable reflector is firstly established in this paper. Then,the computing flow is improved on the basis of the old mini-step displacement computing method and the improved computing method is validated by simulation tests. Finally,the simulation result is analyzed,which indicates that the improved computing method not only satisfies the max force of actuators during the reconfiguration less than the threshold level of actuators but also satisfies that the RMS after the configuration is similar to the RMS after configuration with the old computing method.
