Problems solved by technology
It is the key link for the instant release of the ejection collision of the test bench, which can greatly improve the control accuracy of the ejection speed of the test bench. The ejection collision control device is of great significance for the component level and vehicle crash test research. At present, most ejection collision devices collide with test benches. The speed control error is large and the reaction speed is slow, which affects the response speed of the collision and increases the test error of the ejection collision

Description
technical field [0001] The invention belongs to the technical field of ejection testing, in particular to an ejection collision control device for a test bench. Background technique [0002] An adaptive balanced ejection control device is of great significance to the ejection control of the test bench crash test. It is the key link for the instant release of the ejection collision of the test bench, which can greatly improve the control accuracy of the ejection speed of the test bench. The ejection collision control device is of great significance for the component level and vehicle crash test research. At present, most ejection collision devices collide with test benches. The speed control error is large and the reaction speed is slow, which affects the response speed of the collision and increases the experimental error of the ejection collision. Contents of the invention [0003] The purpose of the present invention is to provide a self-adaptive balanced ejection contr...
