【摘要】：进入新世纪后,各式各样的,国内国外的商品随着物流运输到世界各地,物流的集散地各式各样的包裹也是纷繁复杂,刺激了经济的发展,增加了物流的发展。选择某品牌智能座便器的包装系统为研究载体,通过Creo2.0、ANSYS workbench等软件对外包装和衬垫进行分析,对跌落结果进行分析,判断包装设计是否合理可靠。主要研究过程首先对缓冲包装动力学理论研究进行整合,将一品牌智能座便器化为二自由度三次非线性系统。将陶瓷部分和易损的电子元件盖部作为一个振动系统,坐便器整体与与缓冲枕垫为一振动系统,两个单自由系统构成了二自由度系统。其次利用Creo2.0建立三维模型,导入ANSYS workbench中进行显示动力学分析。设定跌落工况为二层堆码处,进行面跌落,棱跌落,角跌落三种姿态的自由跌落仿真,从而分析包装系统对坐便器的缓冲保护是否可靠。再次对材料属性为EPE的下衬垫进行厚度上的参数优化,实现厚度的尺寸减少,从而减少缓冲材料的使用。在角跌落过程中对于缓冲垫失效的问题进行了衬垫厚度增加的合理化建议。并重新建模仿真对结果进行了验证。
[Abstract]:After entering the new century, various kinds of goods, domestic and foreign goods are transported to various parts of the world with the logistics, and the distribution center of logistics is also complicated, which stimulates the development of economy and increases the development of logistics. The packaging system of a brand of smart seat toilet is selected as the research carrier. The package design is analyzed by Creo2.0,ANSYS workbench and other software, and the drop result is analyzed to judge whether the package design is reasonable and reliable. In the main research process, the theory of cushioning packaging dynamics is integrated, and a brand of smart seat toilet is transformed into a two-degree-of-freedom cubic nonlinear system. The ceramic part and the vulnerable electronic component cover are regarded as a vibration system, the toilet and cushioning cushion are used as a vibration system, and two single free systems constitute a two-degree-of-freedom system. Secondly, the three-dimensional model is built by Creo2.0, and the display dynamics is analyzed by importing it into ANSYS workbench. The free drop simulation of surface drop, edge drop and angle drop is carried out to analyze whether the packaging system is reliable for the buffer protection of the toilet. Thirdly, the thickness parameters of the lower gasket with EPE property are optimized to reduce the size of the thickness and reduce the use of buffer material. In the process of angle drop, the reasonable suggestion of increasing the thickness of cushion is put forward for the failure of cushion. The results are verified by re-modeling and simulation.
