LabVIEW虚拟示波器程序，采用ART USB2831数据采集卡，具有多路数据采集存储和回放功能(It s a program of virtual oscilloscope.The environment is LabVIEW 2010.Using ART USB2831 DAQ.)

说明：  主要用于labview excel读取（源代码）(Mainly used for reading LabVIEW excel (source code))

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

基于matlab的直流斩波电路（buck电路）仿真(buck circuit simulation)

基于Labview的直流电机闭环调速 稳定性好(Labview-based closed-loop DC motor speed control)

实现多通道的应变采集，包括自动清0，手动清0等(Multi-channel strain collection, including cleared automatically, manually cleared, etc.)

PID control。Labview中搭建的程序。经典！！(A program of PID control in Labview.)

说明：  基于阶次分析理论的轴承故障诊断方法，该vi 很有实用价值，希望可以给大家带来帮助。(Bearing fault diagnosis method based on the order analysis theory, the vi Is of great practical value, the hope can bring you help.)

二代小波包分析，能够将选择的文件进行二代小波分解，分解层数为5层(Wavelet packet analysis)

滚动轴承的故障诊断程序，可实现在线诊断和自动识别(Rolling bearing fault diagnosis)
