tion and specialization of production. Production efficiency is not high, poor economic returns. Mold production industry is small and scattered, crossindustry, capitalintensive, professional, mercial and technical management level are relatively low. According to inplete statistics, there are now specialized in manufacturing mold, the product supporting mold factory workshop (factory) near 17 000, about 600 000 employees, annual output value reached 20 billion yuan mold. However, the existing capacity of the mold and die industry can only meet the demand of 60%, still can not meet the needs of national economic development. At present, the domestic needs of large, sophisticated, plex and long life of the mold also rely mainly on imports. According to customs statistics, in 1997 630 million . dollars worth of imports mold, not including the import of mold together with the equipment。 in the application of CAE design and analysis of mold calculation, it was just started, most of the game is still in trial stages and animation。 據(jù)不完全統(tǒng)計(jì),全國現(xiàn)有模具專業(yè)生產(chǎn)廠、產(chǎn)品廠配套的模具車間(分廠)近 17000家,約 60萬從業(yè)人員 ,年模具總產(chǎn)值達(dá) 200億元人民幣。在應(yīng)用 CAD技術(shù)設(shè)計(jì)模具方面,僅有約 10%的模具在設(shè)計(jì)中采用了 CAD,距拋開繪圖板還有漫長的一段路要走;在應(yīng)用 CAE進(jìn)行模具方案設(shè)計(jì)和分析計(jì)算方面,也
