中文摘要：

随着现代绿色农业的发展和物流产业链的变革，新型农产品运输方式受到学者越来越多的关注。针对传统运输方式的缺陷，设计了一种与有压管道配套使用的新型农产品管道车。为了研究该新型农产品管道车的运动性状，分别以雷诺数、车荷重为控制因子研究试验段内该新型农产品管道车的速度变化，对比各测试断面压力水头分析试验段内的压力变化。运用正交试验数据分析，以相对于流速较快的管道车运行速度、较小的压力损失和较重的输送荷载为目标，采用多指标试验设计分析方法建立了综合评分模型。研究结果表明，该管道车在管道内的运动是非匀速的，受此影响，管内液体运动也是非定常的。综合评分模型得出该管道车结构参数对输送性能的变化规律和综合性能最高的指标参数组合，可为该新型农产品管道车研究方案的设计和结构参数的优化提供参考。

英文摘要：

With the development of modern green agriculture and the transformation of the logistics industry chain,the new mode of transpor-tation has drawn more and more attention of agricultural products from scholars. Aimed at the defect of traditional mode of transportation,we designed a matched with pressure pipe with a new type of agricultural products pipeline car. In order to study the new pipeline car movement character of agricultural products,with Reynolds number respectively,car load for the study of the control factors in the test section of the new agricultural products pipeline car speed change,contrast each test section head analysis the pressure variety in the test section. With the orthogonal experiment data analysis,in order to faster the pipeline car speed relative to the flow,small pressure loss and the heavier load as the goal,the integrated assessment model was established by using the multiple attribute test design analysis method. Research results show that the pipeline car movement in the pipe is uniform,as a result,liquid motions are stationary. Synthetically score model car structure pa-rameters on the transmission performance of the pipeline change rule and the comprehensive performance of the highest index parameter com-bination,for the new type of agricultural products pipeline car research plan of design and optimization of structure parameters to provide the reference.
