Research On Washing Machine Transportation Packaging Technology And Performance Evaluation Based On Buffer Of Paper

With the improvement of the domestic transport environment, manufacturers and users pay more attention to the abnormal damage about electrical appliances product in the transport process. Meanwhile, Designing package based on the concept of environmental also become a development trend.Due to paper packaging application prospect and the development of computer technology, this article will research on washing machine transportation packaging technology and performance evaluation based on buffer of paper, Meanwhile, Collecting vibration environment parameters of the actual process with related equipment, then convert the result to experiment standard. Owing to practical model simulation be able to achieve, So this article research on simulation and actual experiment about structure of multilayer honeycomb cardboard energy absorption performance, establish the protective packaging system washing machine based on the honeycomb cardboard corrugated cardboard and the simulation of Workbench.The main research results of this article are as follow:(1) Collecting transportation of vibration environment samples about the electrical appliances product from point A to point B, Using it to test the package vibration level of random through the fourier transform and numerical calculation; With the help of statistics theory, puts forward the original frequency domain of regional vibration spectral into neat spectrum and the process of the spectrum numerical accelerated test calculation; Analyzes the vehicle transportation environment of three direction of the vibration level through measured curve, Then draw The following conclusion: the biggest energy vibration direction is the perpendicular of the ground, low frequency vibration magnitude highter than high frequency area.(2) This article develop the road spectrum signal management and processing system based on the measured signal. The front desk language is VB, the backstage database is Sqlserver. The software could gather all of signal messsge integration into a database. At the same time, The software could achieve the numerical transformation process about original test spectrum to laboratory tests spectrum and generate test spectrum based on the laboratory required test time.(3) This article research two layers of honeycomb paperboard absorb the size of the energy in a certain height about the different thickness of the combination. At the same time, Simulating the dynamic impact test process through the finite element. Through compared with the actual experimental results, draw the following conclusion: if thickness of upper board is increase, per unit volume of double cardboard could absorb more energy.(4) This article design a paper packgage about a particular washing machine of littleswan, then package experiments drop and random vibration test. The results show that: the package could meet the experiment test standard. After test the materials physical parameter of relevant parts, establish the finite element model of entity, which imported to solve in Workbench. Obtain the acceleration and acceleration distribution cloud pictures of inner barrel about face drop and edges drop and angle drop, then compared with the actual experiment results. The result show that packaging project compliance with relevant test standard and has a Engineering application prospect.
