船用低速柴油机的吊具受力复杂且不规则，传统设计通过简化模型计算其理论强度，与实际工况误差较大。文中利用有限元软件ANSYS分析，以6S42MC整机吊具为研究对象，采用三维软件PROE建立该吊具模型并对其进行有限元分析，根据分析所得的应力分布和形变情况，判断吊具的可靠性；通过改变吊具的结构尺寸，对减少吊具应力的方法进行探究；对吊具进行拓扑优化。分析结果表明，文中方法可以检验吊具的安全性，提高经济效益，同时为吊具的理论设计提供了依据。

The forces acted on the low-speed marine diesel engines′spreader are complex and irregular .The tra-ditional design calculates the theoretical strength by simplifying the model ,but it has great errors under the actual working conditions .In this paper ,by using finite element software ANSYS analysis ,we make up for the defects of the traditional design .Model and finite element analysis are mode by the three-dimensional software PROE .Ac-cording to analysis from the stress distribution and deformation ,the reliability of the spreader is judged;the reduc-tion of the stress of the spreader is explored by changing the structure size of the spreader ;the topology optimiza-tion is made .The analysis results proved that we can test the safety of the spreader ,improve the econanic benefit , and provide the basis for the theory of the spreader design .
