Research On System Of Intelligent Dynamic Balancing Machine For Two-plane

Rigid rotor is unbalancing if its axis of rotation is not uniform with its central principal inertia axis,. Unbalance imposes cyclic forces on bearings and shafts, producing vibaration, even damaging machinery. So, balancing technology is one of keys of machine industry development, research of dynamic balance machine has important significance to improvement of industry technology level on both theory and practice.Hard bearing balancing machine has gradually become mainstream of development of dynamic balancing machine because of its obvious advantage. To horizontal two-plane hard bearing balancing machine, this dissertation describes history , actuality and current of dynamic balancing technology as well as typical structure of balancing machine. Two methods of mechanics computation that is influence coefficient method and A－B－C method is detailedly deduced.. Influence coefficient method is applied in measuring system and software about it is designed. Vibration equation of two-plane balancing rotor is derived. Non-linear error of bearing support of hard bearing balancing machine is analysed and relation curve is presented. Design method of elasticity component is expatiated as well as parameter select of vibaration system. New scheme of electric measuring system of intelligent two-plane balancing machine is presented. this scheme overcomes the flaw of many balancing machine and have better performance in anti-jamming and real-time. Its hardware construction and measuring principle is introduced , the software of lower computer and upper computer is designed. To abominable and complicated work condition of dynamic balancing machine and serious jamming, software anti-jamming technology is adopted. Principle of software redundance, software hook, "watchdog" and auto-resume from malfunction is detailedly described and program is designed. Experiments prove this balancing machine is easy to be operated with comparatively higher balance quality and can meet practical requirment of two-plane balancing measuring. Consequently, this machine has better practical value and market foreground.
