【正文】 摘 要 I 基于 Pro/E 的裝載機工作裝置 的 實體建模及運動仿真 專業(yè)： 機械設計制造及自動化 作者： 李書知 指導教師： 陳豐峰 摘 要： 裝載機是一種應用廣泛的工程機械。有其廣泛的空間，但由于裝載機傳統(tǒng)開發(fā)模式存在的開發(fā)周期長、過程繁雜、開發(fā)成本高、性能測試困難等問題，本文將仿真技術引入裝載機開發(fā)領域，完成以下工作： 1． 介紹了裝載機的發(fā)展歷史及前景，裝載機的種類，介紹了仿真技術產(chǎn)生的背景、在國內(nèi)的發(fā)展狀況以及仿真技術的實際意義。 2． 對液壓缸作出了合理的選擇。 3． 簡述了 Pro/E 軟件在工程設計中的應用，利用 Pro/E 構建裝 載機的三維實體模型，并對其進行裝配，在 Pro/E環(huán)境下進行了裝配干涉檢驗。 4． 在 Pro/ENIEER MECHANISM 環(huán)境下進行運動仿真 ,得出裝載機工作的性能曲線。 關鍵字：裝載機 工作裝置 液壓缸 仿真技術 三維建模 Abstract： Loader is a kind of engineer machine that is widely applied in engineer project, which has wildely space, Aim to the problems that exist in traditional research way of loader, for example the research cycle is long, the cost is long, the cost is high and the performance test is plex etc, this paper leads virtual prototype technology into research of loader. The following research works are pleted: 1. The development foreground, the category and loader’s history is introduced, also the background of simulation technology e into being, developing status in local and the significance of virtual prototype technology is introduced. 2. To brief introduce the Pro/E software which application in the field of engineering, the 3D modeling is used by Pro/E software, which is built and interferential test of assembly in Pro/E environment is pleted. 3. The simulated motion in Pro/E environment is pleted, and the capability curve is reached. 4. A rational choice for the hydraulic actuating cylinder. Keywords: Loader, Working mechanism, hydraulic actuating, Simulation technology, 3D modeling 目 錄 II 目 錄 摘 要 ....................................................................................................................................
