KXB型隔爆电控箱的力学分析及优化

Mechanical Analysis and Optimization of KXB Flameproof Electronic Control Box

为了减少隔爆电控箱的设计周期和成本,并校核其强度、减轻其重量,可以使用SolidWorks软件对箱体建模并分析。首先根据防爆要求对螺钉进行校核,接着对电控箱门板以及整箱进行力学分析仿真,并针对其不同失效形式分别进行优化:门板采用加厚的形式提高其强度,箱体采用合适的加肋薄板来增加强度并减轻重量。最终很好地达到了整机的要求。

In order to reduce the design cycle, cost and weight of flameproof electronic control box and check it′ s strength. Use Solid Works to build and analyze the model. First of all, check the screw according to the requirements of the explosion. Then analyze it′s gate and the whole box, and optimize the box according to the different failure mode of the gate and whole box. Increase gate′s thickness to increase it′s strength, and use the right stiffened plant to increase the box′s strength and reduce the box′s weight. Finally, meet the requirements of the machine finely.
