Vibration Test of Bearing Ball Fatigue Testing Machine Based on VB

Abstract

Ball bearing life test, once the failure specimen ball fatigue, if not timely shutdown, will lead to a series of chain reactions caused by the fault processing is not seasonable, serious word may also lead to the damage of equipment. Therefore the vibration test is very important to accurately determine the specimen failure, ball. In this paper, the vibration test for bearing fatigue testing machine, the test results to be real-time and accurate judgment sample ball failure.

Automatic testing system to evaluate the energy efficiency of electric storage water heaters

“…A Visual Basic program not only provides a good user interface (UI) but also has a strong communication function using the computer serial port to conveniently realize the measurement and control. 7 In this work, by combining Microsoft SQL Server 2008, Microsoft Excel 2013, and communication technology in a testing software platform based on Visual Basic 6.0, we propose a novel testing system for evaluating the energy efficiency of water heaters. The testing platform is highly automated, highly efficient, and highly reliable.…”
