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;
4. Measurement and analysis of friction torque and friction characteristic curve of liquid dynamic pressure bearings;
3、 Main performance characteristics:
1. Implemented fully automatic detection and automatic drawing of performance parameter change curves
2. Virtual simulation of pressure oil film distribution curve has been achieved
3. Adopting an elastic loading system can effectively reduce the deformation of the spindle journal
4. Adjustment adopts DC stepless adjustment
★ The device has added a remote communication protocol module, which can achieve:
Remote teaching function:
1) Real time teacher and student one-on-one remote teaching, remote communication function;
2) Manufacturers and equipment administrators provide real-time guidance on equipment operation and maintenance;
Laboratory management functions:
1) The equipment is equipped with a set of laboratory management system software and hardware, implementing a one person, one account mode for administrators. Through the mobile APP communication protocol, administrators with more than 10 people can manage the equipment at any distance, including recording (automatic start) and playback of the equipment operation process, as well as automatically starting the infrared alarm function when the equipment is turned off.
