【摘要】：面對(duì)經(jīng)濟(jì)全球化的今天,我國(guó)機(jī)電產(chǎn)品面臨出口的形勢(shì)已不可避免。電焊機(jī)作為我國(guó)機(jī)電類產(chǎn)品出口的其中一類產(chǎn)品,其運(yùn)輸包裝的性能在整個(gè)運(yùn)輸過程中起著決定性的作用。長(zhǎng)期以來,電焊機(jī)制造企業(yè)不重視運(yùn)輸包裝,包裝形式過于單一,普遍存在欠包裝的問題,導(dǎo)致電焊機(jī)在運(yùn)輸中較容易產(chǎn)生損壞,造成企業(yè)巨大的經(jīng)濟(jì)損失。本文通過對(duì)電焊機(jī)運(yùn)輸包裝技術(shù)及試驗(yàn)的研究,優(yōu)化改進(jìn)了目前主流運(yùn)輸包裝的方式,利用試驗(yàn)的比對(duì),驗(yàn)證其適宜性和有效性。研究主要以危害最大的公路運(yùn)輸為主,首先,對(duì)包裝系統(tǒng)進(jìn)行動(dòng)力學(xué)建模,通過仿真分析各因素對(duì)系統(tǒng)振動(dòng)響應(yīng)的影響,為后續(xù)設(shè)計(jì)提供理論指導(dǎo);其次,利用緩沖包裝設(shè)計(jì)六步法對(duì)目前主流的運(yùn)輸包裝進(jìn)行優(yōu)化設(shè)計(jì),提出創(chuàng)新設(shè)計(jì)方案;最后,通過對(duì)運(yùn)輸包裝試驗(yàn)的研究,選取實(shí)際物流運(yùn)輸過程中遇到的具有代表性的定頻振動(dòng)試驗(yàn),變頻振動(dòng)試驗(yàn)、隨機(jī)振動(dòng)試驗(yàn)和跌落試驗(yàn),將優(yōu)化前后的兩種運(yùn)輸包裝方式進(jìn)行試驗(yàn)比對(duì),對(duì)試驗(yàn)結(jié)果的分析,得出優(yōu)化后的方案在防護(hù)能力上得到了較大的提升,防止電焊機(jī)在運(yùn)輸過程中的損壞,減少企業(yè)在物流輸運(yùn)環(huán)節(jié)上不必要的經(jīng)濟(jì)損失。
[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.
