| 摘 要： | 通过研究以动力激励下结构响应的位移为目标或约束的结构动力学优化设计，利用解析的方法推导出动力位移响应灵敏度计算公式，并成功地移植到有限元程序中。程序在计算包括杆、梁、板、二维、三维单元在内的所有算例时，动力位移响应的灵敏度精度均可达到97％，并且迭代次数少，求解效率高。

| Abstract: | The expression of dynamic displacement response sensitivity was constructed based on analytical algorithm and successfully adopted into a finite element programming. The developed programme can be used for dynamic optimal design for combined structures with a high solving efficiency and a rapid computation speed. The examples, including truss, beam, plate, two- dimensional element and three-dimensional element, indicated that accuracy of dynamic displacement sensitivities reached up to 97%. |
