本文在综述国内外采煤机研发应用及设计方法发展现状与趋势的基础上，针对国内普遍采用的“样机设计→制造物理样机→物理样机试验→改进设计→小批量制造及批量制造”的采煤机研发过程，存在设计效率与设计质量低、研发周期长等不足，以国内某煤矿机械制造企业设计生产的MG900/2210-WD型采煤机为对象，将CAE关键技术应用到采煤机的设计研发过程中，完成了以下主要工作： 利用数字化样机技术，在Solidworks环境下，依据MG900/2210-WD型采煤机初始设计CAD图纸信息建立了三维零部件图库，再通过自下而上的三维装配，建立了采煤机的数字化样机；在软件环境下，通过采煤机数字化样机的运行仿真进行干涉检查，验证了初始结构设计的正确性；依据所建设数字化样机，确定了该型号采煤机的重心位置，为采煤机设计和“三机”选型配套提供了依据；为了进一步研究初始设计的可靠性，对采煤机关键零部件如摇臂、调高油缸、扭矩轴、齿轨轮、滑靴、液压拉杠、截齿等进行了有限元分析，得到了各关键零部件的应力云图及应力应变数据，通过对有限元结果的分析，进而提出了改进建议。 以上研究表明，对于采煤机采用“样机设计→数字化建模→运动学仿真→有限元分析→制造物理样机→物理样机试验→改进设计→小批量制造及批量制造”的研发过程，能有效地提高设计效率与设计质量，大大缩短研发周期，节约研发成本。

The book on the basis of summing up the home and abroad shearers the current situation and trend applying development of method and designing. Aim Shearer R & D process commonly used in domestic as “the model machine design→the model machine made→the model machine testing→revising designed→bigger made and rack” Which exists that the efficiency and quality of design is low and the term of R & D is long. Take the MG900/2210-WD Shearer which is produced in some domestic coal mine machinery manufacturing enterprises as a object and use some of CAE technology to the design of Shearer applications. And made the following job: Use digital prototyping technology, and applicate Solidworks to set up a library of three-dimensional parts of the Shearer WG900/2210-WD with CAD drawings in strict accordance, and assemble for the whole through bottom-up, then set up the digital prototype of Shearer. Take the kinematics simulation, check the prototype interference of model, and verify the correctness of the initial structural design. In modeling, based on the location of the shearer to determine center of gravity, provide the basis for "Three-machine" selection and the shearer design. In order to further study the reliability of the initial design, Take the Finite element analysis of the key components of Shearer , such as Rocker, an increase in the fuel tank, shaft torque, gear-track wheels, sliding shoes, hydraulic pull bars, pick, etc , and get the cloud of stress and stress-strain data of key parts, analysis the results of finite element and put forward suggestions for improvement Research shows that the R & D process of shearer as “the model machine design→3-D builds the model→kinematics analysis→finite element analysis→the model machine made→the model machine testing→bigger made and rack” can effectively improve the design efficiency and design quality, greatly short the development cycle ,and save the cost of R & D .
