【摘要】 汽车在行驶过程随路面起伏和刹车过程,不可避免地引起车身振动并消耗能量。本研究尝试将汽车的振动能转换为对气体的压缩功,驱动脉管制冷机制冷,从而达到回收能量的目的。由于惯性,高质量的活塞在汽缸中相对自由运动,产生压力波,从而驱动汽缸两端各自连接的脉管冷机产生冷量。本文基于汽车一般路况的振动频率,给出了理论计算过程,考察了活塞质量对压力波及制冷量的影响。在此基础上设计制造了整套系统。更多还原

【Abstract】 It’s inevitable of the vibration when a vehicle stops and runs over a bumpy road,which wastes the energy.Attempts to convert the vibration into the driving power for tne compression of the gas,and obtains the refrigerating effect with the pulse tube cooler system.The piston with large mass is moving within the column since the inertia,thus,generates the pressure wave and drives the two pulse tube coolers,which install on the two ends of the column.Presents and discusses the theoretical analysis including the effects of the piston mass on the amplitude and cooling power based on the assumptions of the general situations of the road.Introduces the whole mechanical system as well as the parts in detail.更多还原
