摘要:

应用有限元压缩柔度矩阵,建立了具有接缝传荷能力多块板的位移计算方法.在此基础上,根据系统识别原理,应用修正牛顿法作为参数调整算法建立了具有接缝传荷能力的弹性地基多块板结构材料性能的反演分析方法.反算结果表明,在相当大的模量初始值范围内,该方法具有稳定的收敛性.

Abstract:

Using the finite element compression flexibility matrix, a displacement calculation method for multiple plates with seam load transfer capacity was established. On this basis, according to the principle of system identification, the modified Newton method is applied as the parameter adjustment algorithm to establish an inversion analysis method for the material properties of elastic foundation multi-block plate structure with joint load transfer capacity. The backcalculation results show that the method has stable convergence in the range of large modulus initial values.
