查询词典 piston

There was an increasing demand for engine power due to industrial development. As early as the 2nd century BC, the ancient Greeks invented an engine that was powered by the reaction from spurting steam; in 1690, the Frenchman Barben invented the first piston steam engine. On the basis of his predecessors' work and with his own hard work and numerous trials and failures, James Watt invented the steam engine with connecting rod, flywheel and centrifugal speed governor in 1782.In 1784, the British government granted a patent to James Watt for producing steam engines, which signified that man had entered the age of the steam engine and also significantly expedited the beginning of the Industrial Revolution in 18th century Europe. By the 1830s, steam engines had been widely used in various sectors such as textile, metallurgy, coal mining and transportation; for example, the American Robert Fulton invented the steamboat and the Englishman George Stephenson invented the steam locomotive.

随着社会的进步，社会由农业时代进入工业时代后，对全用手工操作已十分不满足，人们随着工业发展对动力的需求日益突出，瓦特在前人研究蒸汽的基础上，甚至早在公元前二世纪，古希腊人创造的一种利用蒸汽喷射的反作用的发动机，以及1690年法国人巴比首先发明第一台活塞式蒸气机等，刻苦钻研，反复实验，经历无数次挫折和失败，终于在1782年发明了具有连杆、飞轮和离心调速器的双动作蒸气机，使之成为了可以实用的蒸气机。1784年英国政府授予瓦特以制造蒸气机的专利证书，这标志着人类进入了蒸气机时代，有力地促进了欧洲18世纪的产业革命。

Numerical simulation by Matlab for the new hypocycloid energy transformation mechanisms was done by means of the four-order Runge-kutta's method. The result shows that the simple harmonic and rectilinear motion of piston in the new mechanism make the engine working more stable. The peak acceleration is around 25% lower in the new mechanism than that in the conventional slider-crank mechanism. And the output speed is much higher at the same identical mean effective pressure and same load torque. And then the output power of the engine is improved.
