摘　　要：与弹性结构相比,粘弹性结构的动力分析更为复杂和困难。本文借助于求解复阻尼问题的思想,给出了求解粘弹性杆系结构稳态响应的计算公式及算例。为进一步研究粘弹性结构的动力行为,还讨论了一个考虑转动效应的Burgers粘弹性梁的自振特性。Compared to elastic structures,the dynamic analysis for visco-elastic structure is more complicated and difficult.By virtue of idea for solving the problem of complex damping,the computing formulas of steady-state response for visco-elastic frame structure are derived and numerical examples are exhibited in the paper.For further study in dynamic behavior of visco-elastic structures the characters of free vibration for a Burgers visco-elastic beam with rotating effect are also discussed.
