中文拼音 [làliàochéngxíngmó]
落料成形模
英文
blanking and shaping die-
More than 100 sets of hot forging sets specially manufacture some large - scale bolts, ( process including blank, forging, chamfer and rolled thread ) screw rolling machines. the company has become a specialty that can produce all bolts, big or small, from m6 - m56 in specifications
熱鍛專用設備100餘臺（套） ，專門製作一些大規模螺栓， （工序從落料、打頭、倒角、滾絲）滾絲機，公司就形成了大小螺絲都能生產的專業戶，規格從m6一直到m56 。In this paper, by using non - linear finite element software, ansys / ls - dyna, simulate a forming of auto fall to ground skeleton part, get the contour of the semi - finished product, forecast the change of the blank thickness and the probable wrinkling, cracking, and from the simulation of the spring - back, obtain the spring - back tendency. so, get technology parameters, which are inextricable to forming production. all these will pose great significant to production in theory and reality
本文運用非線性有限元軟體ansys ls - dyna對汽車落地骨架零件進行了沖壓成形的數值模擬，得出了毛坯外形，預測了成形過程中板料壁厚變化和可能出現的起皺、破裂現象，通過回彈模擬，預測了回彈趨勢，獲得了該類零件成形所需要的工藝參數，對實際生產具有一定的指導作用。By the net - shape forming technology, metal sheet is used as a blank, the cylindrical cup is produced through blanking, deep drawing, and etc, and then the cup is clamped to a mandrel rotated together with the main spindle, the pulley is finally produced by several different spinning rollers, which apply the radial spinning forces to the cup in different positions
鈑制帶輪是以金屬板料為毛坯，經過落料、拉深等沖壓工序製成圓筒狀，然後將其裝夾在帶有頂壓座的芯模上，使其隨主軸一起旋轉，通過若干不同齒形的旋壓成形輪分別沿徑向施加壓力而成形。Based on the above purpose, in this paper, aiming at the questions in the past landslide prediction, such as sole research technique, backward method and theory achievement with weak practical, application and so on, time prediction and evaluation of landslides is emphatically researched from quantitative, qualitative and numerical modeling three aspects on the basis of widely consulting the domestic and foreign documentation and material related to landslides forecast. according to landslide monitor material, landslide quantitative prediction is realized by using landslide prediction and evaluation models ; on the basis of experts " experience knowledge, landslide qualitative prediction is realized by using the method and way of expert system ; landslide numerical prediction is realized by using simulation method to establish geology - mechanics - distortion model ( gmd )
基於上述目的，本論文針對過去滑坡預報的研究方法單一、手段落後，理論成果的實際應用性不強等問題，在廣泛查閱國內外有關滑坡預測預報文獻資料的基礎上，著重從定量、定性和數值模擬三個方面對滑坡的時間預測預報開展研究：依據滑坡的監測資料，運用滑坡預測預報模型實現了滑坡的定量預報；以專家的經驗知識為依據，運用專家系統的方法和手段實現了滑坡的定性預報；利用數值模擬手段，通過建立滑坡的地質?力學?變形模型（ gmd模型）實現了滑坡的數值預報。分享友人
