【正文】 大型龍門機(jī)床滑枕的三維結(jié)構(gòu)設(shè)計(jì)及有限元分析[摘要]大型龍門機(jī)床具有加工跨距大、加工效率高等特點(diǎn)，適用于大尺寸零件的高精度加工，在航空、船舶、汽車等領(lǐng)域應(yīng)用廣泛。橫梁是龍門機(jī)床的主要支承部件，其結(jié)構(gòu)和靜力學(xué)特性直接影響機(jī)床的加工精度。 本課題針對陜西漢川機(jī)床有限公司正在研發(fā)的某型定梁龍門機(jī)床，應(yīng)用SolidWorks軟件對其滑枕進(jìn)行三維結(jié)構(gòu)設(shè)計(jì)，然后應(yīng)用ANSYS軟件，對其進(jìn)行靜力特性分析，計(jì)算滑枕在切削力和自重作用下的變形和應(yīng)力，驗(yàn)證設(shè)計(jì)是否滿足機(jī)床的精度要求，并繪制設(shè)計(jì)圖紙。 SolidWorks軟件是世界上第一個(gè)基于Windows開發(fā)的三維CAD系統(tǒng)。資料顯示，目前全球發(fā)放的SolidWorks軟件使用許可約28萬，涉及航空航天、機(jī)車、食品、機(jī)械、國防、交通、模具、電子通訊、醫(yī)療器械、娛樂工業(yè)、日用品/消費(fèi)品、離散制造等分布于全球100多個(gè)國家的約3萬1千家企業(yè)。在教育市場上，每年來自全球4，300所教育機(jī)構(gòu)的近145，000名學(xué)生通過SolidWorks的培訓(xùn)課程。 ANSYS軟件是融結(jié)構(gòu)、流體、電場、磁場、聲場分析于一體的大型通用有限元分析軟件。由世界上最大的有限元分析軟件公司之一的美國ANSYS開發(fā)，它能與多數(shù)CAD軟件接口，實(shí)現(xiàn)數(shù)據(jù)的共享和交換，如Creo,NASTRAN, Alogor, I－DEAS,AutoCAD等， 是現(xiàn)代產(chǎn)品設(shè)計(jì)中高級CAE工具之一。 [關(guān)鍵詞]滑枕、靜力特性、分析、SolidWorks、ANSYSThreedimensional structure of large gantry machine ram design and Their Finite Element analysisAbstract:Large gantry machines with processing large span, high efficiency machining for large size precision machining parts, widely used in aviation, marine, automotive and other fields. Beam gantry machine is the main support member, the structure and static mechanical properties directly affect the machining accuracy.The topic for the Shaanxi Hanchuan Machine Tool Co. is developing a fixedbeam gantry machine tool, SolidWorks software applications designed for its threedimensional structure of the ram, and then using ANSYS software, its static characteristics analysis to calculate the cutting force ram and deformation and stress under its own weight, to verify whether the design meets the accuracy requirements of the machine, and draw the design drawings.SolidWorks software is the world39。s first Windowsbased development of threedimensional CAD system. Statistics show that the current global release of SolidWorks software licenses to about 280,000, involving aerospace, lootive, food, machinery, defense, transportation, mold, telemunications, medical equipment, entertainment industry, modity / consumer products, discrete manufacturing, global distribution more than 100 countries around 30,001 thousand enterprises. In the education market, each year nearly 145,000 students from 4,300 educational institutions worldwide through SolidWorks training courses.ANSYS software is the financial structure, fluid, electric, magnetic, acoustic analysis in one of the large generalpurpose finite element analysis software. United States developed the world39。s largest ANSYS finite element analysis software from one pany, it interfaces with most CAD software, sharing and exchange of data, such as Creo, NASTRAN, Alogor, IDEAS, AutoCAD, etc., is a modern product design one seni
