基于随机可靠度的300MN模锻水压机主工作缸壁厚的设计

Design of Wall Thickness of the Main Cylinder of a 300MN Hydraulic Die Forging Press Based on Random Reliability

300MN模锻水压机是国防和基础建设的关键设备,主工作缸是水压机的重要部件之一。本文根据概率法设计了主工作缸的壁厚,所设计的主工作缸壁厚只有传统设计壁厚的35%,有效的减轻了主工作缸重量。主工作缸壁厚的偏差变化对其可靠度有一定的影响,在生产制造中很有必要对壁厚的偏差进行控制。本文为主工作缸的设计提供了参考依据。

According to the probability law,the main cylinder wall thickness has been designed,which is only 35% of the originally used,effective reduction of the weight of the main cylinder.The deviation change of the main cylinder wall thickness has some influence on its reliability,it is necessary to control the thickness deviation in the manufacture.
