中文摘要:
      双螺杆榨油机中榨笼作为压榨部分的关键部件,其对榨膛内挤油压力的形成和对两根螺旋轴的支撑起到关键作用。针对目前传统经验设计的榨笼尺寸和质量偏大,造成制造材料浪费的问题,将双向渐进结构优化方法(Bi-Directional Evolutionary Structural Optimization, BESO)应用到榨笼的设计中。以榨笼的刚度最大化为目标,以体积为约束条件,在Abaqus环境下,采用Python程序实现BESO优化算法,设计出新的榨笼结构。通过优化设计前后的对比分析表明,新的结构在满足强度要求的条件下,质量减少了35.1%。该优化分析方法为后续的榨笼设计提供了一种新思路。
英文摘要:
      Bar-cage of twin-screw press is the key component, which plays a key role in forming the pressure of squeezing oil and supporting the two screw shafts. According to present problems of the traditional experience design, the size and weight of bar-cage are too large, which causes material waste.The bi-directional evolutionary structural optimization method (BESO) was applied to the design of the bar-cage. The optimization objective of design was the maximum stiffness for the bar-cage subjected to a volume constraint. The BESO was implemented with Python program in the Abaqus. Finally, a new bar-cage structure was designed. The comparative analysis of the new structure and original structure showed that the weight of new structure reduced by 35.1%, and it could also meet strength requirement.And a new thinking of the design of bar-cage was offered by this optimization analysis method.
