要
平衡重式电动叉车由于其操作控制简便、灵活，其操作人员的操作强度要求 相对内燃叉车而言轻很多，广泛使用在国民经济的各个部门，其电动转向系统、 加速控制系统、 液压控制系统以及刹车系统都由电信号控制大大降低了操作人员 的劳动强度， 这样一来对于提高其工作效率以及工作的准确性有非常大的帮助且 相较于内燃叉车电动车辆的低噪音、无尾气排放的优势也得到许多用户的许可。 如何更好的发挥其优势来取代内燃叉车，对环保有重大意义。本课题研究运用计 算机仿真技术对电动叉车进行虚拟设计， 在产品制造之前将运用 AutoCAD 完成平 衡重式电动叉车变速器、货叉及整车装配的二维绘制，为之后的 Pro/E 软件的三 维图绘制做铺垫， 然后将用 Pro/E 软件对平衡重式电动叉车的各个零件进行三维 绘制并进行整车装配，为之后的 ANSYS 分析建立三维模型,最后将运用 ANSYS 软 件进行仿真研究，就可以发现并更正设计缺陷，完善设计方案，缩短开发周期， 提高设计质量和改善，为生产实际提供理论支持。 关键词：电动叉车；变速器；货叉；三维建模；有限元分析
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.
