摘　　要：隧道挖装机是隧道施工的重要机械,而工作装置则是隧道挖装机中的关键组成部分。利用虚拟样机技术以相应软件为手段对隧道挖装机工作装置进行反求设计。首先根据现场测绘得出的图纸,利用三维造型Pro/E软件对隧道挖装机工作装置组成零件进行三维几何造型,按照其正确装配方式进行整体组装。并按照一定格式把组装好的Pro/E几何造型文件导入到动力学软件ADAMS中,进行调试、定义属性等环节进一步建立了挖装机工作装置虚拟样机,按照其运动规律及油缸相应参数对隧道挖装机工作装置进行运动仿真设计,并编写相应剧本进行运行,根据虚拟样机中设置的测量点在运行之后得出的数据图表确定工作装置的特殊工作尺寸如最高挖掘点、最低挖掘点、最大转动半径、最大转动角等,并给出相应截图。绘制出机构在运动过程中的相应轨迹图并予以分析。经与实际样机工作参数比对,误差在允许范围内,验证了虚拟样机的反求能力。Tunnel Backhoe Loader as an important machine in the tunnel execution of works,the working device is taken as the key part.This thesis uses the technology of virtual prototype to design it combined with software related.Firstly,it uses 3-D model software PRO/E to model the parts of the Tunnel Backhoe Loader according to the mapping got in the field,and then makes them up in a correct way.After that it imports the file from Pro/e into ADMAS,debugs them,and defines the property,and so on,to build the virtual prototyping of the Tunnel Backhoe Loader.It makes the motion simulation of the Tunnel Backhoe Loader according to the sports law and the parameter of the cylinder,and writes program to drive it,gets the special parameters,such as the maximum excavation point,the minimum excavation point,the maximum turning radius,the maximum rotation angle,and etc according to the data chart of the measuring point,which are setting depend on virtual prototyping.Draw the locus of the machine when it acting,and analyze them.Compared with the parameter of the actual prototype,the error is permitted.
