转台是铁路起重机关键构件之一，其强度和刚度是否满足要求将直接影响到整机的性能。以一种160 t双回转铁路救援起重机为研究背景，基于ANSYS有限元仿真软件，首次对包含旋转伸缩配重在内的转台部分进行参数化建模，并完成了结构分析，避免了以往等效配重力矩带来的误差；在此基础上，对转台各部分的板厚进行了优化，有效地降低了转台的重量，为今后铁路起重机的设计提供了参考。

Turntable is one of the railway crane ’ s key components ,its strength and stiffness have a direct impact on the perform-ance of complete appliance .Based on the finite element analysis software-ANSYS,takes a kind of 160t double rotary rescue rail-way crane as the research background ,and completed the parametric modeling and structure analysis of the rotating platform in-cluding the flexible counterweight for the first time .Thus avoiding the errors brought by the equivalent weight before .On this ba-sis,the optimization of every plate thickness was calculated .As a result,the weight of the rotary table has a significant reduction . This will provide a reference for the design of railway crane in the future .
