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。
In order to solve the problem of local strength checking in traditional design, the first-order optimization algorithm is used to optimize the design and calculation of the lifting arm. Based on the optimization results, the stress-strain analysis of the whole suspension tanker truck is carried out. The calculation results show that the optimized strength of the lifting arm and the frame meets the design requirements. The larger overall stress of the lifting arm appears at the bottom of the guide plate and the guide plate of the guide plate supporting the middle tank. The larger overall stress of the frame At the bottom of the round with the walking round the arc segment, the design process should be appropriately strengthened local strength of these parts.
