轴的计算机辅助设计计算(含CAD零件图)

轴的计算机辅助设计计算(含CAD零件图)(任务书,开题报告,外文翻译,论文说明书10000字,CAD图纸1张)
摘要
轴是重要的机器零件之一，它的设计主要包括结构设计及强度，刚度校核两部分。轴的设计是十分繁琐的过程，特别是再按疲劳强度进行精度校核时，需要检索大量的图表，作大量的运算。通常这一过程由有一定经验的工程技术人员进行。由于计算过程繁杂，所以一旦校核合格一般不重新进行，即使在安全系数余很大的情况下也是如此。
随着计算机技术的发展，计算机正在越来越广泛地应用于机械设计的各个方面以及各种各样的机械设计中，它在提高机械设计的质量和转化为实际制造的效率方面，发挥着重要作用。计算机辅助设计便是伴随着计算机技术的发展而出现，并广泛应用于多种学科的一种方法。计算机辅助设计又被称作“CAD”，是由计算机帮助设计人员完成机械设计中的计算、制图、模拟等工作，并在不断修改和反复验证的基础上，输出满意的设计结果和最后的产品图纸的一门技术。
设计过程编成计算机程序，大量的检索，计算及绘图任务由计算机来完成，这不仅能提高设计速度，改善设计质量，还能把有经验的设计人员从繁琐劳动中解放出来，从事更有意义和研究性的工作。 [资料来源：Doc163.com]

Axis computer-aided design
Abstract
Axis is an important part of the machine, its design includes structural design and strength, rigidity checking two parts. Axis design is a very tedious process, especially the fatigue strength and then checking the accuracy, you need to retrieve a large number of charts, for a large number of operations. Usually this process by having some experience engineering and technical personnel. Complex process of calculation, so once the check is generally not re-pass, even in the case of large safety factor than the well.
With the development of computer technology, computers are becoming more widely used in all aspects of mechanical design and a variety of mechanical design, mechanical design it to improve the quality and efficiency of manufacturing into practical aspects play an important effect. Computer-aided design is accompanied by the emergence of computer technology, and is widely used in a variety of disciplines in a way. Computer-aided design, also known as "CAD", was completed by the computer to help the designer in the calculation of mechanical design, drafting, simulation, etc., and constantly modify and repeated verification, based on the output of a satisfactory outcome and final product design drawing a technical.

    Compiled computer program design process, a large number of retrieval, calculation and drawing tasks done by the computer, which not only can improve the design speed, improve design quality, but also the experienced designers freed from tedious labor, engaged in more meaningful and research work.
