Stamping Technics Simulation Of Car Wheel Cover Strengthening Sheet

Sheet metal stamping is an important method of sheet metal forming,especially in the auto manufacturing.As we all know,most of the automotive body panel and structure are made by sheet metal stamping.For the auto industry ,the competition core in 21 century will be the new product competition.How to achieve high quality,low cost and short leadtime in the new auto type exploitation is the key to win this competition.Now,only depending on the traditional experience design is not enough to adjust to the new conditon , the auto body incorporated technology which taking CAE as the center ,is becoming the focus of the auto industry. Among of them-the sheet metal forming simulation technology.is the most important.The sheet metal forming simulation technology plays an important role in improving the level of auto designing ,the quality of manufacture and the efficiency.It?ˉs also the only way to improve the competition ability of our country?ˉs auto market.The essential of the stamping simulation is analysing the whole deforming progress of sheet metal in which the mould and technics project are given by numerical simulation thchnique, so we can judge the rationality of the mould and the technics project.Each time of simulation is equivalent to one time of stamping.So,the mature simulation technique not only can reduce the times of try-stamping and under some condition we can have the mould and thchnics design satisfy our requirements one time without repairing mould.In that case,we can greatly shorten the leadtime of the new product,reduce the exploitation cost,improve the quality and maket competition power of the product.In the past the designing of the mould mainly depend on the long-term accumulated experience of the engineer.For complicated forming thchnics and mould,it?ˉs hard to ensure the design quality;some critical design parameter can only be ascertained after the mould is manufactured and through repeating testing,modification.In this case,we waste plenty of manpower,material resources and time.Along with the fenitee lement thenique and computer thchnology development ,numerical simulation has gradually become the effective tool of thchnics analysing and optimization designing.The auto body panel has complicated shape,large size,thin sheet metal and higher surface quality requirements.so the stamping technology and the designing of the mould is a very complicated technic work,and is also the bottleneck of the development of our country?ˉs auto industry.In order to improve...
