【正文】 當(dāng)時(shí)世界先進(jìn)水平。經(jīng)過(guò)幾年的努力，在吸收當(dāng)時(shí)世界最先進(jìn)的輪式裝載機(jī)技術(shù)的基礎(chǔ)上，開(kāi)發(fā) 成功了功率為 162KW 的鏟接式輪式裝載機(jī)，定型為 Z450(即后來(lái)的 ZL50)，并于 1971 年 12 月 18 日正式通過(guò)專家鑒定。 裝載機(jī)的發(fā)展 我國(guó)現(xiàn)代輪式裝載機(jī)起始于 20 世紀(jì) 60 年代中期的 Z435 型。此外還可進(jìn)行推運(yùn)土壤、刮平地面和牽引其他機(jī)械等作業(yè)。換裝不同的輔助工作裝置還可進(jìn)行推土、起重和其他物料如木材的 裝卸作業(yè)。最后利用材料力學(xué)對(duì)工作裝置進(jìn)行校核。河南理工大學(xué)畢業(yè)設(shè)計(jì)論文（說(shuō)明書(shū)） I 裝載機(jī)鏟斗運(yùn)動(dòng)機(jī)構(gòu)設(shè)計(jì) 摘要 裝載機(jī)， 是一種廣泛用于公路、鐵路、建筑、水電、港口、礦山等建設(shè)工程的土石方施 工 機(jī)械，它主要用于鏟裝土壤、砂石、石灰、煤炭等散狀物料，也可對(duì)礦石、硬土等作輕度鏟挖作業(yè)。 本文以 TZ08D 型裝載機(jī)為例 , 先介紹了 TZ08D 裝載機(jī)工作裝置結(jié)構(gòu)，利用 AUTOCAD2021 對(duì)裝載機(jī)工作裝置進(jìn)行初步設(shè)計(jì)，然后利用 Pro／ E 軟件進(jìn)行裝載機(jī)工作裝置的三維實(shí)體設(shè)計(jì)，以真實(shí)地反映裝載機(jī)的幾何形狀進(jìn)而反映出各部件空間位置，有效地反映裝載機(jī)真實(shí)結(jié)構(gòu)，提供直觀形象的實(shí)體圖形，為進(jìn)一步動(dòng)態(tài)仿真和有限元分 析做準(zhǔn)備。 關(guān)鍵詞 ：裝載機(jī)， Pro/ENGINEER，虛擬裝配 ABSTRACT Wheel loader is one machine extensively used for highway, railroad, construct, water electricity, port, mineral mountain etc and mainly used for a spade to pack soil, freestone, lime, coal...etc. to spread a form material. It can also make a light degree spade to dig homework to the mineral stone, hard soil etc. With the TZ08 D wheel loader for a example, this text firstly introduce its structure and give preliminary designing with the help of AUTOCAD2021 , then asking for help of Pro/E software to carry on loading machine work device of 3D entity design for really reflecting loading machine of several the shape then reflects their position of each parts effectively and introduce its instruction to resolve a problem in time. Finally, using the material mechanics to check work device.
