【摘要】：面对经济全球化的今天,我国机电产品面临出口的形势已不可避免。电焊机作为我国机电类产品出口的其中一类产品,其运输包装的性能在整个运输过程中起着决定性的作用。长期以来,电焊机制造企业不重视运输包装,包装形式过于单一,普遍存在欠包装的问题,导致电焊机在运输中较容易产生损坏,造成企业巨大的经济损失。本文通过对电焊机运输包装技术及试验的研究,优化改进了目前主流运输包装的方式,利用试验的比对,验证其适宜性和有效性。研究主要以危害最大的公路运输为主,首先,对包装系统进行动力学建模,通过仿真分析各因素对系统振动响应的影响,为后续设计提供理论指导;其次,利用缓冲包装设计六步法对目前主流的运输包装进行优化设计,提出创新设计方案;最后,通过对运输包装试验的研究,选取实际物流运输过程中遇到的具有代表性的定频振动试验,变频振动试验、随机振动试验和跌落试验,将优化前后的两种运输包装方式进行试验比对,对试验结果的分析,得出优化后的方案在防护能力上得到了较大的提升,防止电焊机在运输过程中的损坏,减少企业在物流输运环节上不必要的经济损失。
[Abstract]:In the face of economic globalization today, China's mechanical and electrical products are facing the situation of export is inevitable. As one of the export products of mechanical and electrical products in China, the performance of the transport packaging of the welding machine plays a decisive role in the whole transportation process. For a long time, welding machine manufacturers do not attach importance to transport packaging, packaging form is too single, there is a widespread problem of under-packaging, resulting in welding machine in the transport more easy to produce damage, resulting in huge economic losses of enterprises. Based on the research on the transport packaging technology and test of electric welding machine, this paper optimizes and improves the current mainstream transport packaging mode, and verifies its suitability and effectiveness by comparing the experiments. Firstly, the dynamic modeling of the packaging system is carried out, and the influence of each factor on the vibration response of the system is analyzed by simulation, so as to provide theoretical guidance for the follow-up design. Secondly, the six-step method of cushioning package design is used to optimize the current mainstream transport packaging, and the innovative design scheme is put forward. Finally, through the study of the transport packaging test, the representative constant frequency vibration test, frequency conversion vibration test, random vibration test and drop test encountered in the actual logistics transportation process are selected. By comparing the two transport packaging methods before and after optimization, and analyzing the test results, it is concluded that the optimized scheme has been greatly improved in terms of protection ability, thus preventing the damage of electric welding machine in the course of transportation. Reduce the enterprise in logistics transport link unnecessary economic losses.
