摘?? 要
平衡重式電動叉車由于其操作控制簡便、靈活，其操作人員的操作強度要求相對內(nèi)燃叉車而言輕很多，廣泛使用在國民經(jīng)濟的各個部門，其電動轉(zhuǎn)向系統(tǒng)、加速控制系統(tǒng)、液壓控制系統(tǒng)以及剎車系統(tǒng)都由電信號控制大大降低了操作人員的勞動強度，這樣一來對于提高其工作效率以及工作的準確性有非常大的幫助且相較于內(nèi)燃叉車電動車輛的低噪音、無尾氣排放的優(yōu)勢也得到許多用戶的許可。如何更好的發(fā)揮其優(yōu)勢來取代內(nèi)燃叉車，對環(huán)保有重大意義。本課題研究運用計算機仿真技術(shù)對電動叉車進行虛擬設計，在產(chǎn)品制造之前將運用AutoCAD完成平衡重式電動叉車變速器、貨叉及整車裝配的二維繪制，為之后的Pro/E軟件的三維圖繪制做鋪墊，然后將用Pro/E軟件對平衡重式電動叉車的各個零件進行三維繪制并進行整車裝配，為之后的ANSYS分析建立三維模型,最后將運用ANSYS軟件進行仿真研究，就可以發(fā)現(xiàn)并更正設計缺陷，完善設計方案，縮短開發(fā)周期，提高設計質(zhì)量和改善，為生產(chǎn)實際提供理論支持。

ABSTRACT
Counterbalanced electric forklift operation control because of its simple, flexible, and its operator's operations in terms of strength requirements are relatively much lighter internal combustion forklifts, widely used in various sectors of national economy, the electric power steering system, the speed control system, hydraulic control system and control the brake system greatly reduces the signal by the operator's labor intensity, so that its work for improving the efficiency and accuracy of the work has a very big help, and internal combustion forklift electric vehicles compared to the low noise, no exhaust emissions advantage by many users permission. How to better play to their strengths instead of internal combustion forklifts, of great importance to environmental protection. This study is the use of computer simulation technology for electric forklifts for virtual design, manufacturing completed before the use of AutoCAD transmission counterbalanced electric forklift, fork and two-dimensional vehicle assembly drawing for the following Pro/E, three-dimensional map pave the way to draw, and then use the Pro / E software counterbalanced electric forklift parts for all three-dimensional drawing and make the vehicle assembly, after the ANSYS analysis for the establishment of three-dimensional model, and finally the use of ANSYS simulation software, can be found and correct design flaws and improve the design, shorten the development cycle, improve design quality and improvement, provide theoretical support for the actual production.
