【摘要】：目前,叉車行業(yè)有著良好的發(fā)展前景,同時也面臨著激烈的競爭。為了適應市場需求,促進叉車的系列化設計,加快新產品開發(fā)速度,提高整機的性能和質量,本課題嘗試開發(fā)了一套適用于叉車總體設計的專業(yè)CAD軟件。 以平衡重式叉車為研究對象,具體探討了總體計算、部件選配可視化、穩(wěn)定性試驗可視化、總體布置圖參數(shù)化和文檔自動化技術等內容�；诿嫦驅ο蟮姆椒�,分析了總體設計的要求及其CAD系統(tǒng)的功能。將該CAD系統(tǒng)劃分為若干模塊,并具體分析了主要模塊的結構和功能。通過系統(tǒng)集成技術將各個模塊有機的結合在一起,以實現(xiàn)叉車總體設計的功能。以3.5t叉車為例,介紹了該CAD系統(tǒng)的基本操作以及總體設計的一般流程。 穩(wěn)定性試驗與叉車的安全性密切相關。在探索總體設計CAD的過程中,基于計算機圖形學理論,本課題重點研究了叉車穩(wěn)定性試驗的可視化模擬。通過分析穩(wěn)定性試驗的原理和過程,揭示了穩(wěn)定性試驗和空間變換的內在聯(lián)系,并抽象出了簡化的三維試驗模型。采用三維幾何變換,能描述穩(wěn)定性試驗中一系列的平移和旋轉運動;應用軸測投影變換,可以解決三維試驗模型在二維設備中的顯示問題。因此,基于空間變換方法,采用Visual C++編程實現(xiàn)了叉車穩(wěn)定性試驗在計算機屏幕上的動態(tài)顯示,從而完成了穩(wěn)定性試驗的可視化模擬。 該CAD系統(tǒng)集成了可視化設計、參數(shù)化設計、文檔自動化技術和數(shù)據(jù)庫技術等,并在三維可視化方面做了深入地研究。這種軟件的開發(fā)思路和方法對CAD技術在工業(yè)車輛設計中的應用具有一定的意義。
[Abstract]:At present, forklift industry has a good development prospects, but also faces fierce competition. In order to meet the market demand, promote the serial design of forklift truck, speed up the development of new products, and improve the performance and quality of the whole machine, this paper tries to develop a set of professional CAD software suitable for the overall design of forklift truck. Taking the balanced heavy forklift truck as the research object, this paper discusses in detail the contents of the overall calculation, the visualization of component selection, the visualization of stability test, the parameterization of the overall layout plan and the technology of document automation, etc. Based on the object-oriented method, the requirements of the overall design and the functions of the CAD system are analyzed. The CAD system is divided into several modules, and the structure and function of the main modules are analyzed in detail. In order to realize the function of the overall design of forklift truck, all modules are organically combined by system integration technology. Taking 3.5 t forklift as an example, this paper introduces the basic operation of the CAD system and the general process of the overall design. The stability test is closely related to the safety of forklift truck. In the course of exploring the overall design of CAD, based on the theory of computer graphics, this paper focuses on the visual simulation of forklift truck stability test. By analyzing the principle and process of the stability test, the internal relationship between the stability test and the spatial transformation is revealed, and the simplified three-dimensional test model is abstracted. The 3D geometric transformation can describe a series of translation and rotation motions in the stability test, and the axial projection transformation can be used to solve the display problem of the 3D test model in the two-dimensional equipment. Therefore, based on the spatial transformation method, the dynamic display of the forklift stability test on the computer screen is realized by using Visual C programming, and the visual simulation of the stability test is completed. The CAD system integrates visual design, parametric design, document automation and database technology. The development idea and method of this software have certain significance for the application of CAD technology in industrial vehicle design.
