Arm Based Wince Platform Rotor Dynamic Balancing

Rotor is the indispensable key components from basic daily home apparatus to the high-tech fields such as various industry productions, transport equipments as well as aerospace and aviation. The vibration due to the imbalanced quality of the rotor will cause a variety of mechanic malfunctions. Therefore, it is necessary to have rotor dynamic balancing.This paper is to consider the engine power (roller) as its subject. Combined with the characteristic of power of the rotor, it is aimed to analyze how to handle the dynamical balanced signals, the design of the relative hardware circuit, the premium realization of the dynamical balancing method as well as the design of the human-computer interaction interface. The main contents of this paper are illustrated as follows:(1) This paper is aimed to realize the high-precise measurement of the rotation velocity of the rotor, PLL, the distance control amplification of the rotation signals, the spontaneous trace of the diluted wave, the design of high-precise and high-velocity A/D convert. Meanwhile, this paper is to abstract feature vector of the basic frequency from the unbalanced rotation signals by using FFT.(2) This paper is to make an authentic analysis on the respective circuit models by using the authentic circuit software Multisim and Protues.(3) Least Square Influence Coefficient Method is to be modified based on particle group, that is to combine the intelligent search for the premium of POS with Least Square Influence Coefficient Method which is widely applied in the present dynamical balancing technique. This method has been confirmed to be able to realize better balancing effects from the test results.(4) The embedded WinCE system is characterized with the separation of the software and hardware, high reliability, low costs, small volume, low energy consumption as well as flexible design. Based on the research of developing the platform of embedded NETARM2410-S, this paper is to design a set of dynamical balancing system software endowed with friendly human-computer interaction interface.
