普通v带参数化设计系统 毕业设计论文.doc

摘 要 在随着科学技术的发展，机械制造业的应用十分广泛。特别是在农业机械、工程机械、 军事应用当中占据着重要位置。在进入工业时代以来，机械制造始终是创造社会财富的主要来源是衡量国家综合国力的重要指标In with the development of science and technology, mechanical manufacturing used widely. Especially in agricultural machinery, construction machinery, application of military occupy an important position. In the industrial age since, machinery manufacturing is always create the main source of social wealth, it is to measure countries an important index of the comprehensive national strength. And for manufacturing, such as some large-scale mechanical equipment, are generally will depend on the mechanical transmission provide needed power, and in the mechanical transmission in the V belt type the most traditional and it is also the most widely the mechanical transmission. Therefore, master V belt transmission design is very important and necessary. This article used the mechanical design method, through the vb software powerful functions, making common v belt parameterization system implemented, and the traditional design method than, greatly improve work efficiency, reduce a lot of time. In general, the design includes establishing mathematics model and programming. When the design of the system is completed, we can get a visual interface, the interface can input some known conditions and the program automatically calculation, and obtained the corresponding results. In addition, vb to more easily, and can establish friendly interface, its function is more practical, easy to understand object-oriented programming, this also is the design of the reason for selecting vb.
