機械設計專業(yè)相關的畢業(yè)設計論文，里面有詳細的圖紙，ppt,說明書，外文翻譯。

[摘要] 水稻是我國的主要糧食作物，占全國谷物種植面積30%，產量占全國糧食產量40%，南方丘陵地區(qū)水稻種植面積約占全國的1/2，但田塊小,土地高低不平，一般0.01～0.1公頃/塊。南方水稻區(qū)地處丘陵地帶，田塊主要以梯田、爛泥田、不連塊、道路窄等為特點，選用小型聯合收割機為宜，行走裝置采用履帶式，以適應水田作業(yè)。
本論文是設計4LZ-1200水稻聯合收割機的行走機構，以適應南方丘陵稻區(qū)水田作業(yè)。首先分析行走機構的行走原理，確定與行走機構通過性能有關的整機參數。再分析接地比壓和轉向能力，增強其防陷、轉向能力。然后設計行走輪系結構，根據聯合收割機工作特點和系統(tǒng)的構成特點，利用履帶傳動原理對聯合收割機的行走系統(tǒng)進行設計，計算各部件的結構尺寸并進行校核，繪制出詳細結構圖，并做運動仿真。

Design the traveler of the 4LZ-1200 Rice Combine

[Abstract] Rice is China's main food crops, accounting for 30% of cultivated area of grain production accounted for 40% of the national grain output, the South Hills area of rice cultivation areas across the country about 1 / 2, but the Field small, rugged land, generally 0.01 ~ 0.1 hectares / block. Rice is located in the south hills area, mainly in Field Terrace, muddy fields, not even block, features such as narrow roads, appropriate selection of small combines, crawler running devices used to meet the paddy field operations.
In this paper, it is designed to combine the traveler of 4LZ-1200 Rice Combine in order to adapt to the south hills area of paddy field operations. First analysis the operating principle of the traveler to identify the machine parameters about the walk through the performance of traveler. Re-analysis of ground pressure and steering capabilities, to enhance its anti-depression, steering ability. And then walk round the design structure, in accordance with the work combines the characteristics and composition of the characteristics of the system, the use of crawler drive combines the principle of running the system design, calculation of the structure of the various components and check the size, structure chart to map out in detail, and simulation exercise.
