摘要
针对传统设计中局部强度校核的不足,运用一阶优化算法对提升臂进行了有限元优化设计计算,并结合优化结果对全悬挂式中间罐车进行整体结构受力变形分析。计算结果表明:优化后的提升臂及车架整体强度满足设计要求,提升臂较大综合应力出现在支撑中间罐的钢板导圆弧段与导轮支撑板的底部,车架较大综合应力出现在底部与行走轮联接的导圆弧段,设计过程中应适当加强这些部位的局部强度。
Aiming at the deficiency of the local strength verification in the traditional design,the optimizing design of the lifting-hand is analyzed based on first-order optimizing arithmetic.At the same time,the analysis of the overall structure deformation of the full-hung tundish car is carried out by use of the finite element method.The results show that the overall strength of the lifting-hand and main frame meets the design requirements.Larger multiply stress of the lifting-hand exits in the leading arc part on the steel plate supported the tundish and the bottom of the steel plate supported the guide pulley.On the other hand,larger multiply stress of the main frame occurs in the leading arc parts which are used to connect the main frame with the driving wheels.Therefore,local strength of these positions should be adapted to strengthen during the course of the practical design.
