Description

technical field [0001] The invention relates to a control system of a test bench, in particular to a control system of a high-frequency braking test bench. Background technique [0002] With the advancement of science, high-speed machining, as an advanced mechanical manufacturing method, has attracted widespread attention and developed rapidly in developed countries. For high-speed machining, fast positioning is a very important technology. With the improvement of processing speed and precision, the positioning accuracy of the system also needs to be improved accordingly. At the same time, in order to improve work efficiency, the positioning system is also required to respond quickly, accelerate and brake quickly so as to achieve rapid positioning. However, conventional braking technology is difficult to achieve high-speed and high-precision positioning requirements, so it is urgent to explore the high-frequency braking mechanism and develop a high-frequency braking test b...

Problems solved by technology

[0004] At present, there have been experiments in the world using piezoelectric ceramic materials to build high-frequency braking test benches; however, piezoelectric ceramic materials have low strain coefficient, small output force, small electromechanical coupling coefficient, and poor heat resistance. , which has great limitations in application to high-frequency braking

At present, there is no precedent for applying giant magnetostrictive materials to braking systems, and there is no related control system that provides control support for high-frequency braking test benches based on giant magnetostrictive materials.
