中文摘要:
      为了进一步提高安全阀上料的自动化水平,课题组提出了一种能够独立完成上料工作的自动上料车。上料车升降机构在上料过程中的动力学状况对工作中的运动和稳定性具有较大的影响,因此需要对上料车升降机构进行动力学分析。课题组首先简化固连的复杂刚体,利用SolidWorks三维软件建立简化后的上料车三维模型;然后采用拉格朗日法建立动力学方程;最后将三维模型导入ADAMS进行动力学仿真分析,得到了上料车升降机构运动过程中电机驱动扭矩、螺杆受力和滑动轴承受摩擦力的曲线。结果表明:上料车升降机构在运动过程中具有较高的可靠性和稳定性。该研究为上料车升降机构主要部件的选型制造提供了参考。
英文摘要:
      In order to further improve the automation level of safety valve feeding, the research group proposed a safety valve automatic loading car which can independently complete the loading work. The dynamic state of the lifting mechanism of the loading car has a great influence on its motion and stability during the loading process. Therefore, it is necessary to carry out dynamic analysis on the lifting mechanism of the loading car. Firstly, the complex rigid body was simplified, and the simplified three dimensional model of the loading car was established by using SolidWorks software; secondly, the dynamic equation was established by Lagrange method; Finally, the three dimensional model was imported into Adams for dynamic simulation analysis, and the curves of motor driving torque, screw force and sliding shaft bearing friction force were obtained. The results show that the lifting mechanism of the loading car has high reliability and stability in the process of movement. The research provides a reference for the selection and manufacture of the main parts of the lifting mechanism.
