| 中文摘要: |
| 为提高预充式注射器的推杆装置上料效率，课题组基于EDEM软件的JKR模型进行仿真分析，以推杆为研究对象，以规定时间段内出料数为评价指标，探究了内转盘转速、外转盘转速、内转盘倾斜角、锥形盘角度和外转盘半径对推杆出料效率的影响。首先通过单因素分析，确定了各单因素的影响程度，筛选出影响程度更大的4个因素，再设计进行4因素3水平正交试验，确定了最佳参数组合及各因素对出料效率的影响程度顺序；然后，对出料稳定性进行了研究，得到了最佳进料方式；最后进行了试验验证。结果表明：仿真和试验的最大误差为9.6%，说明该模型的模拟分析是可靠的；最佳参数组合情况下，比原始数据出料效率提升了29.8%。 |

| In order to improve the feeding efficiency of the push rod device of the pre filled syringe, the simulation analysis was carried out based on the JKR model of EDEM software. With the push rod as the research object and the discharge number in specified time period as the evaluation index, the influences of the inner tray rotation speed, the outer tray rotation speed, the tilt angle of the inner rotation tray, the angle of the cone trayand the outer rotation radius on the discharge efficiency of the push rod were investigated. Firstly, single factor analysis was carried out to determine the influence of each single factor and screen out the four factors that with greater influence. Then the orthogonal design of four factors and three levels was carried out to determine the optimal parameter combination and the order of the influence degree of each factor on the discharge efficiency. The discharge stability was studied and the best feeding method was obtained. Finally, the experimental validation was carried out. The results show that the maximum error of simulation and test is 9.6%, which indicates that the simulation analysis of the model is reliable. Under the condition of the best parameter combination, the discharge efficiency is improved by 29.8% compared with the original data. |
