Manipulate mechanism with concentrative link lever has important significance to improve maneuverability of bulldozer currently . this thesis includes : designing manipulate mechanism with concentrative link lever and simply calculating force and displacement for operation , based on the referring existing manipulate mechanism of bulldozer ; using high - grade 3 - dimensional plotting software ug ( unigraphics ) to sculpt ; using adams ( automatic dynamic analysis of mechanical systems ) to establish virtual prototyping model and do kinematic simulation . the results verify the rationality of this mechanism and provide the basis for trial - manufacture of physical prototyping and betterment design 本文做的主要工作是:參考推土機原有的變速轉向操縱機構,設計了集中連桿操縱機構并進行操縱力和操縱行程的簡單計算;使用高檔三維造型軟件ug (全稱unigraphics )進行推土機集中連桿操縱機構的造型設計;應用機械系統運動學/動力學仿真分析軟件adams ( automaticdynamicanalysisofmechanicalsystems )對所設計的機構建立虛擬樣機,并進行運動學仿真分析,驗證了機構設計的合理性,為物理樣機的試制和改進設計提供了依據。

Through the using of adams ( automatic dynamic analysis of mechanical systems ) , kinematics simulations , which are based on the designed new type manipulate mechanism with concentrative link lever , are executed . interferences lying in the former model are measured accurately 本論文使用機械系統運動學/動力學仿真分析軟件adams ( automaticdynamicanalysisofmechanicalsystems )對設計的新型推土機集中連桿操縱機構進行了運動學仿真分析,精確測量了存在的聯動角度。

Variable voltage and variable frequency ( vvvf ) inverter control technology applied by ford passenger lift extends the utilization from the elevators drive system to the door machine system , plus its matching none link lever synchronous belt type door machine structure , it results in the more smooth sensitive and secure door open and shut . the passengers feel the doubled warmth in entering into and exiting the elevators 福德乘客電梯所應用的變壓變頻( vvvf )逆變器控制技術,從電梯驅動系統延伸運用到了門機系統中,加上與之相匹配的無連桿同步帶式門機結構,使電梯門的開啟和關閉更加平穩、靈敏和安全,令進出電梯的乘客倍感親切。

Manipulate mechanism with concentrative link lever integrates functions , such as steering n shift and operating direction , into one operating lever . with this mechanism , driver can realize all the operations of bulldozer using elbow joint ' s action 集中連桿操縱機構取消了傳統的轉向、變速及換向操縱桿,將轉向、換向與變速操縱功能集成在一根操縱桿上,利用肘關節的自然動作控制操縱桿實現轉向、前進后退和變速。

At present , adoptive new - style manipulate mechanisms abroad are mainly manipulate mechanism with concentrative link lever and that linked forerunner with link lever 目前,國外采用的新式操縱機構主要有集中連桿操縱機構和先導與連桿操縱相結合的操縱機構。
