ZRJX-HKA type

The experimental desk is completely simulated with an example of an example in the "Mechanical Principles" textbook. It can be used as the speed, acceleration simulation and actual testing experiments, and speed fluctuation adjustment experiments. The simulation and measured curves are exactly the same as the instances in textbooks. Deepen students' understanding of the two chapters of the speed analysis and speed fluctuation adjustment of the plane mechanism.

The experiment configuration adapts to the AD card collected by high -speed dynamic parameters and uses microcomputer control to process data processing and prints the results of the experiment, so that students can master modern dynamic parameter testing technology.
