摘要:
为调控索穹顶结构形状、提高刚度、减少内力,在索穹顶结构中装入了能够改变构件长度的作动器.以结点位移、容许应力、作动杆作动范围为约束条件建立内力优化模型,目标是使结构工作状态系数f最小.利用蚁群随机搜索算法求出该优化模型的最优解.最后以一平面索穹顶结构为算例进行计算,验证了本算法的可行性及控制效果.此算例根据作动器安装位置的不同,分11种工况分别讨论控制效果.结果表明,蚁群随机搜索算法易于收敛,可以得出较好解;各工况的内力均不同程度地实现了优化,其中在内圈斜索设作动器的工况下,内力的优化效果最好;索穹顶结构通过杆件长度的调整,可达到形状调整、受力最优的目的.
Abstract:
Actuators which can change members’ length actively are introduced into cable dome for shape adjustment, enhancing the stiffness and reducing the interal forces. An internal force optimization model is established for minimizing the working state coefficient subjected to the restricted nodal displacements, allowable stress and working parameters of the actuator. The optimal solution of the optimization model is obtained by the ant colony search algorithm. The control effects are discussed in 11 different conditions according to the installation position of the actuator. Finally, a planar cable dome is studied as a numerical example to verify the feasibility and effectiveness of the optimization algorithm. The results show that the ant colony search algorithm is easy to converge, and a better solution can be obtained. The internal forces of each working condition are optimized in different degrees, and the internal force optimization effect of the condition that the actuator is installed in the inner diagonal cable is the best; the shape of the cable dome can be adjusted and the force can be optimized through the length adjustment of the member.
