| 摘 要： | 近年来,现代控制论中的状态空间法在工程领域中得到了应用。由于该方法有效地解决了多输入、多输出的问题,并能方便地上机运算,所以发展较快。文章应用空间问题柱坐标系下的控制方程,通过变换求得状态方程,然后设定势函数进行求解,并以一个简支弯梁为例,进行了验证计算。该方法经改进后,便可应用于被广泛采用的箱形截面的弯桥结构分析计算。

| Abstract: | In recent years,the state space method of modern control theory has been applied in engineering fields.This method has dealt with multi-input/output problem effectively,it also can be calculated with computer,so its development is relatively rapid.Based on control equation of the space problem in cylindrical coordinates,the state equation is derived through transformation,then to get the solution with assumed potential function.A simple curved beam calculation is presented as an example.The method will be used for the calculation of the curved box beam. |
