摘要
通过模型实验与有限元电算,研究了大型升船机塔柱的自振特性。并实验了悬挂船厢及平衡重对塔柱自振特性的影响。比较了前六阶电算与实验的频率与振型,结果吻合较好。最后简单地介绍了塔往地震内力特性。
Based on the modei test and computation by the finite element method, this paper maks investigation on the self-oscillation characteristics of tower column for a big-scale vertical shiplift . In the test the influence of suspend ed chamber and balance weight on the self-oscillation characteristics was observed . By making a comparison between the computa1:ions by electronic computer (with six stages) and the tested results of naturai frequencies and oscillation mode, they are fairly consistent . At last, the characteristics of earthquake internai stress of tower column are described in brief.
