机械设计Mechanical Design(中文3500字,英文2300字)
机器是机构与其他零件的组合，为了有益的用途而转换、传递或利用能量、力或者运动实例有发动机、涡轮、车辆、卷扬机、印刷机、洗衣机和电影摄影机.许多适用于机器设计的原理和力法也适用于不是真正机器的制成品，从轮毂盖和档案橱柜到仪表和核压力容器。“机械设计”这一术语比“机器设计”更为广义，它包括机器设计。而对于某些仪器，如用以确定热、流动线路和体积的热力以及流体方面的问题要单独考虑。但是，在机械设计时要考虑运动和结构方面的问题以及保存和封装的规定。在机械工程领域以及其他工程领域应用机械设计，都需要诸如开关、凸轮、阀门、容器和搅拌器等机械装置。

Mechanical Design
Abstract:
A machine is a combination of mechanisms and other components which transforms, transmits, or utilizes energy, force, or motion for a useful purpose. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines, from hub caps and filing cabinets to instruments and nuclear pressure vessels. The term "mechanical design" is used in a broader sense than "machine design" to include their design. For some apparatus, the thermal and fluid aspects that determine the requirements of heat, flow path, and volume are separately considered. However, the motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers.
