基于Workbench刀砧的热-结构耦合分析

Thermal-structure coupling analysis of knife anvil based on the Workbench software

本文首先通过Solidworks建立了刀砧三维参数模型,基于workbench软件对其进行了静力学结构分析,得出了其应力、应变及方向变形的情况;其次,基于workbench对刀砧进行稳态热分析,然后利用顺序耦合的方法,把刀砧热分析得出的温度场以体积力形式导入静态结构中进行热-结构耦合分析,最后得出了刀砧在热-结构耦合应力作用下的应力、应变及其方向变形,结果表明热应力对刀砧的应力、应变及方向变形影响较大。

The three-dimensional parametric model has been established to the knife anvil by use of Solidworks in the text. The static structure of the knife anvil has been analyzed based on the workbench software. The stress, strain and directional deformation have been obtained. Secondly, the steady thermal analysis of the knife anvil has been performed based on the workbench. Then, by use of sequential coupling method, the temperature field obtained by thermal analysis of knife anvil has been introduced into the static structure in the form of volumetric force for thermal-structure coupling analysis. Finally, the stress strain as well as the directional deformation of the blade anvil under the thermal-structure coupling stress have been obtained. The results show that the thermal stress has bigger impact on the stress, strain and directional deformation of the knife anvil.
