【摘要】：轉(zhuǎn)子的動(dòng)平衡問(wèn)題一直以來(lái)都是機(jī)械領(lǐng)域研究的熱點(diǎn)問(wèn)題。人們?yōu)榱双@得處理速度更快、精度更高、更加方便攜帶的測(cè)試系統(tǒng)，對(duì)測(cè)量系統(tǒng)進(jìn)行不斷地改進(jìn)。本文從硬件和軟件兩個(gè)方面對(duì)系統(tǒng)進(jìn)行論述和設(shè)計(jì)。 本系統(tǒng)以ARM芯片為處理器，操作系統(tǒng)為L(zhǎng)inux，圍繞信號(hào)處理及軟件平臺(tái)設(shè)計(jì)了一款測(cè)量板，包括硬件部分和軟件部分。其中硬件由信號(hào)調(diào)理電路、A/D轉(zhuǎn)換、ARM處理器三部分組成。振動(dòng)信號(hào)經(jīng)過(guò)傳感器轉(zhuǎn)換為相應(yīng)電信號(hào)，接下來(lái)信號(hào)調(diào)理電路對(duì)其進(jìn)行處理得到A/D接受范圍的信號(hào)，再由A/D轉(zhuǎn)換為數(shù)字信號(hào)，最后經(jīng)過(guò)ARM處理器進(jìn)行信號(hào)處理，信號(hào)處理部分為不平衡量的求解，最后在顯示屏上顯示不平衡量的幅值和相位。軟件方面設(shè)計(jì)包括Linux系統(tǒng)的制作、A/D采集程序、信號(hào)處理程序和界面開(kāi)發(fā)程序。其中制作Linux系統(tǒng)是為了得到滿足系統(tǒng)要求的最小系統(tǒng)以達(dá)到占有少量存儲(chǔ)空間的目的。A/D采集程序和信號(hào)處理程序是在ARM處理器中運(yùn)行的對(duì)信號(hào)處理的程序。由于ARM可以外接觸摸屏，，所以通過(guò)設(shè)計(jì)軟件界面可以在觸摸屏上實(shí)現(xiàn)良好的人機(jī)交互。通過(guò)在軟件界面上的參數(shù)設(shè)置可以對(duì)不同轉(zhuǎn)子進(jìn)行不同的處理并且可以顯示相應(yīng)的不平衡量的幅值和相位。 本文所設(shè)計(jì)的動(dòng)平衡測(cè)試系統(tǒng)，通過(guò)配合不同的傳感器可以對(duì)大部分轉(zhuǎn)子進(jìn)行測(cè)試。
[Abstract]:The problem of rotor dynamic balance has always been a hot issue in the field of machinery. In order to obtain a test system with higher processing speed, higher precision and more convenient to carry, the measurement system is continuously improved. This paper discusses and designs the system from two aspects of hardware and software. The system uses ARM chip as processor and operating system as Linux. A measuring board is designed around signal processing and software platform, including hardware and software. The hardware consists of three parts: signal conditioning circuit, A / D converter and arm processor. The vibration signal is converted into the corresponding electrical signal by the sensor. Then the signal conditioning circuit processes the signal to get the signal in the range of A / D, and then the signal is converted from A / D to a digital signal. Finally, the signal is processed by the ARM processor. The signal processing part is the solution of the unbalance. Finally, the amplitude and phase of the unbalance are displayed on the display screen. The software design includes the design of Linux system A / D acquisition program, signal processing program and interface development program. The purpose of making Linux system is to obtain the minimum system to meet the system requirements and to occupy a small amount of storage space. The acquisition program and signal processing program are signal processing programs running in the ARM processor. Because ARM can connect the touch screen, the software interface can be designed to achieve good man-machine interaction on the touch screen. By setting the parameters on the software interface, different rotors can be processed differently and the amplitude and phase of the corresponding unbalance can be displayed. The dynamic balance test system designed in this paper can test most rotors with different sensors.
