发布时间:2018-08-17 18:29
【摘要】:转子的动平衡问题一直以来都是机械领域研究的热点问题。人们为了获得处理速度更快、精度更高、更加方便携带的测试系统,对测量系统进行不断地改进。本文从硬件和软件两个方面对系统进行论述和设计。 本系统以ARM芯片为处理器,操作系统为Linux,围绕信号处理及软件平台设计了一款测量板,包括硬件部分和软件部分。其中硬件由信号调理电路、A/D转换、ARM处理器三部分组成。振动信号经过传感器转换为相应电信号,接下来信号调理电路对其进行处理得到A/D接受范围的信号,再由A/D转换为数字信号,最后经过ARM处理器进行信号处理,信号处理部分为不平衡量的求解,最后在显示屏上显示不平衡量的幅值和相位。软件方面设计包括Linux系统的制作、A/D采集程序、信号处理程序和界面开发程序。其中制作Linux系统是为了得到满足系统要求的最小系统以达到占有少量存储空间的目的。A/D采集程序和信号处理程序是在ARM处理器中运行的对信号处理的程序。由于ARM可以外接触摸屏,,所以通过设计软件界面可以在触摸屏上实现良好的人机交互。通过在软件界面上的参数设置可以对不同转子进行不同的处理并且可以显示相应的不平衡量的幅值和相位。 本文所设计的动平衡测试系统,通过配合不同的传感器可以对大部分转子进行测试。
[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.
