动载滑动轴承油膜分布及压力同步采集研究

Simultaneous Pressure Measurement and High Speed Photography Study of Cavitation in a Dynamically Loaded Journal Bearing

对滑动轴承试验台进行了改造,使得油膜分布以及油膜压力同步采集成为可能。介绍了压力采集的电路设计以及程序设计。测试结果表明,实验台的改造设计是合理的,数据采集的电路设计是实用的,采集数据的程序方便直观,硬件设施和软件编程都方便可靠。

To acquire photos of cavitation and pressure in film simuhaneously,a test rig on journal bearing was rebuilt and designed. The circuit of acquiring pressure and software programming was introduced. Experimental result shows that the rebuilding and design of the test rig on journal beating is reasonable, data acquiring is convenient.
