Experimental project content:

The purpose of the experiment is to use the experimental object, that is, the full process of the dynamic balance of the rotor, and the necessary hands -on operations, so that students can basically master

1) Basic concepts of rotating dynamic balance

2) Understand the principles of dynamic balance and work

3) The operation method of determining and application of dynamic balance during the dynamic balance of the rotor

 

M--n functions and characteristics:

1) Virtual intelligence test instrument interface, virtual instrument technology is used to make the interface beautiful, image, and friendly. The experimental results are displayed at the same time in numbers, curves and graphics. The experimental process is vivid and easy to operate;

2) The balance of hard support is settled by A, B, and C. The permanent standard has six support methods;

3) Real -time prompts of exercise status, panel with LED speed display;

4) Have the set function of the surplus unsatisfactory measurement, automatic prompts to qualify;

5) Dynamic process experiments can be performed. This system can not only staticly display the experimental results, but also perform continuous dynamic process experiments. During the experimental rotation, three window pupae were opened through the m--n interface of the data analysis. At the same time, the curve of the post -signed signal filter, the actual eccentric volume distribution diagram, and the actual phase distribution diagram were dynamically displayed. By observing the changes in the dynamic curve, students can understand the principles, methods, and results of the dynamic balance experiment more deeply;
