BR-ZCS (II) intelligent liquid dynamic sliding bearing analysis experimental platform

1、 Overview:
The adjustment method of the loading load on this experimental platform is completely digital control, so programmable loading can be carried out, making the experimental operation process more convenient and concise. A microcontroller was installed in the control box of the experimental platform, and dedicated software was designed to enable the experimental platform to have various artificial intelligence capabilities. And it can be connected to a PC (this experimental platform is already equipped with an interface), automatically displaying the experimental curve.
2、 Main experimental content:
1. Test and analysis of radial distribution of oil film pressure in liquid dynamic pressure bearings;
2. Simulation analysis of radial distribution of oil film pressure in hydrodynamic bearings;
3. Test and analysis of axial distribution of oil film pressure in liquid dynamic pressure bearings;
