大型龙门机床滑枕的三维结构设计及有限元分析 [摘要]大型龙门机床具有加工跨距大、加工效率高等特点，适用于大尺寸零件的高精度加工，在航空、船舶、汽车等领域应用广泛。横梁是龙门机床的主要支承部件，其结构和静力学特性直接影响机床的加工精度。 本课题针对陕西汉川机床有限公司正在研发的某型定梁龙门机床，应用SolidWorks软件对其滑枕进行三维结构设计，然后应用ANSYS软件，对其进行静力特性分析，计算滑枕在切削力和自重作用下的变形和应力，验证设计是否满足机床的精度要求，并绘制设计图纸。 SolidWorks软件是世界上第一个基于Windows开发的三维CAD系统。资料显示，目前全球发放的SolidWorks软件使用许可约28万，涉及航空航天、机车、食品、机械、国防、交通、模具、电子通讯、医疗器械、娱乐工业、日用品/消费品、离散制造等分布于全球100多个国家的约3万1千家企业。在教育市场上，每年来自全球4，300所教育机构的近145，000名学生通过SolidWorks的培训课程。 ANSYS软件是融结构、流体、电场、磁场、声场分析于一体的大型通用有限元分析软件。由世界上最大的有限元分析软件公司之一的美国ANSYS开发，它能与多数CAD软件接口，实现数据的共享和交换，如Creo,?NASTRAN, Alogor, I－DEAS,?AutoCAD等， 是现代产品设计中高级CAE工具之一。 [关键词]滑枕、静力特性、分析、SolidWorks、ANSYS  Three-dimensional structure of large gantry machine ram design and Their Finite Element analysis Abstract: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 fixed-beam gantry machine tool, SolidWorks software applications designed for its three-dimensional 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 worlds first Windows-based development of three-dimensional CAD system. Statistics show that the current global release of SolidWorks software licenses to about 280,000, involving aerospace, locomotive, food, machinery, defense, transportation, mold, telecommunications, medical equipment, entertainment industry, commodity / consumer products, discrete manufacturing, global distribution more than 100 countries around 30,001 thousand enterprises.
