　　开发流程

　　Development process

　　一、拟定需求分析。依据功能、功能、作业环境等因素，与客户一起拟定具体的用户需求说明书，进而确定开发方针。

　　First, formulate demand analysis. According to the function, function, working environment and other factors, work out specific user requirements specification with customers, and then determine the development policy.

　　二、开始计划规划。依据需求分析，进行计划拟定，包括功能及参数设定、基础核算、制造开始三维总等作业，进而与客户进行开始检查。

　　2. Start planning. According to the needs analysis, plan formulation, including function and parameter setting, basic accounting, manufacturing start three-dimensional total operations, and then check with customers.

　　三、具体计划规划。听取初审定见，实施计划规划。修正细化三维模型总图，制造零件三维图，对结构部件进行有限元分析及动态模仿。进而与客户进行二次检查。

　　3. Specific planning. Listen to the opinions of the preliminary examination and approval, and implement the plan. Revise and refine the general drawing of the three-dimensional model, manufacture the three-dimensional drawing of the parts, and carry out finite element analysis and dynamic imitation of the structural parts. And then carry out a second inspection with customers.

　　四、终究计划确定及图纸制造。听取二审定见，修正计划规划。制造平面图（如零件图、部件装配图和总装配图，涂装图等），出零件表、易损件清单。

　　4. Final plan determination and drawing manufacture. Hear the opinions of the second instance and revise the plan. Manufacture plan drawings (such as part drawings, assembly drawings and general assembly drawings, painting drawings, etc.) and produce parts list and list of vulnerable parts.

　　五、制造全部技能文件，包括宣扬及技能样本、产品运用说明书。

　　5. Manufacture all skills documents, including publicity and skills samples, product application instructions.

　　台手动挖掘机面世今已有130多年的前史，期间阅历了由蒸汽驱动斗反转挖掘机到电力驱动和内燃机驱动反转挖掘机、运用机电液一体化技能的全自动液压挖掘机的逐步开展过程。台液压挖掘机由日本发明成功。因为液压技能的运用，20世纪40年代有了在拖拉机上配装液压反铲的悬挂式挖掘机，20世纪50年代初期和中期相继研制出拖式全反转液压挖掘机和履带式全液压挖掘机。初期试制的液压挖掘机是采用飞机和机床的液压技能，短少适用于挖掘机各种工况的液压元件，制造质量不行稳定，配套件也不完全。从20世纪60年代起，液压挖掘机进入推广和蓬勃开展阶段，各国挖掘机制造厂和种类添加很快，产值猛增。1968-1970年间，液压挖掘机产值已占挖掘机总产值的83%，目前已挨近100%。

　　The first manual excavator has a history of more than 130 years since it came out. During this period, it has experienced the gradual development process from steam-driven bucket reversal excavator to electric-driven and internal combustion engine-driven reversal excavator, and fully automatic hydraulic excavator with electromechanical and hydraulic integration skills. The first hydraulic excavator was invented by Japan. Because of the application of hydraulic technology, there were suspended excavators equipped with hydraulic backhoes on tractors in the 1940s. In the early and middle 1950s, pulled full reverse hydraulic excavators and crawler full hydraulic excavators were developed one after another. The hydraulic excavator manufactured in the early stage is based on the hydraulic skills of aircraft and machine tools. It is suitable for hydraulic components of excavators under various working conditions. The manufacturing quality is not stable and the supporting parts are incomplete. Since the 1960s, hydraulic excavators have entered the stage of promotion and vigorous development. Manufacturers and types of excavators in various countries have increased rapidly, and their output value has increased sharply. From 1968 to 1970, the output value of hydraulic excavators has accounted for 83% of the total output value of excavators, and now it is close to 100%.

　　挖掘机，又称挖掘机械（excavating machinery)，是用铲斗挖掘高于或低于承机面的物料，并装入运输车辆或卸堆料场的土方机械。挖掘的物料主要是土壤、煤、泥沙以及通过预松后的土壤和岩石。从近几年工程机械的开展来看，挖掘机的开展相对较快，而挖掘机作为工程建设中主要的工程机械机型之一，其正确的选型也就显得更为重要。

　　Excavators, also known as excavating machinery, are earthmoving machines that use buckets to excavate materials above or below the surface of the machine and load them into transport vehicles or unload them to the yard. The excavated materials are mainly soil, coal, sediment and pre-loosened soil and rock. In recent years, the development of construction machinery is relatively fast. As one of the most important types of construction machinery, the correct selection of excavators is more important.
