摘要转子是机械系统的重要部件之一，它是旋转机械系统中最为重要的激振源，由于它的不平衡原因引起的机械振动会造成设备产生振动、噪声甚至部分零件的破坏，特别是对高速旋转的柔性转子，它所产生的机械振动会异常明显，由于转子不平衡而发生的故障大概占机械总故障的六成以上，它会减弱机械设备的工作能力并且减少仪器的工作时长，最坏的状况就是会造成旋转轴承的损坏，全部机组都会遭到破坏，工作人员的安全难以保障。跟着现今精密数控加工技术前进的步伐，高速转子在加工生产的过程中所发生的严重干扰到其加工精度的动平衡问题就显得格外的引人注目，动平衡设备的产生就能非常有效率的确保仪器工作时候的稳定与安全，经济因素和社会因素都能得到保障，因此它的发展有着重大的实际意义。动平衡可以分为以下两种：机上动平衡，现场动平衡。跟着当今社会科技的不断进步，现场动平衡仪根据它的方便性、性价比高、使用简单等优点广泛使用在社会及企业中。该设计认真的学习和研究了动平衡硬件，最终目的是能设计出一款便携的动平衡设备。46278

ABSTRACT When the rotor is one of the important parts of the mechanical system, it is the most important source of excitation system of rotating machinery and mechanical vibration caused by the unbalance will result in the equipment vibration, noise and even parts of the damage, especially for high-speed rotation of the flexible rotor, it generated by mechanical vibration will obviously abnormal, which occur due to the rotor imbalance fault probably accounted for more than 60% of total failure of mechanical, it will reduce the working performance and efficiency of the mechanical equipment and reducing the equipment the use of long, more serious situation will cause the shaft fracture and damaged the whole unit, the threat to the staff safety. Move forward along with the current precision NC machining technology of pace, serious interference occurred in the process of production and processing of high-speed rotor to the machining precision of the dynamic balancing problem is particularly compelling, dynamic balancing instrument produced can be very efficient ensure the stability and safety of the equipment operation, it can get good economic benefits and social benefits, so it has a great practical significance. The dynamic balance can be pided into the following two kinds: the dynamic balance of the machine, the dynamic balance of the scene. In this paper, an in-depth analysis and Research on the field dynamic balance software and hardware system is designed to develop a portable instrument for the field dynamic balance. 动平衡分析仪硬件设计+电路图:http://www.youerw.com/zidonghua/lunwen_47953.html
