Dynamic Analysis and Experimental Research of Linear Cylinder with New Cushioning Structure
The high-speed cylinder has a built-in relief valve cushioning structure,which uses the pressure adjustment to achieve the cushioning effect in the work.But there will be a energy loss and difficulties in valve adjustment.In view of this,a new type of elec-tromagnetic cushioning structure was proposed,the electromagnetic cushioning structure and the dynamic model of high-speed cylinder were established.The test data and simulation results were basically consistent,a good cushioning effect was gotten when the cylinder run to the end of the stroke.At the end of the stroke,the speed oscillated and decelerated to 0,and reached the end point gently.The correct-ness of dynamic model and simulation model is verified.At the same time,the cushioning effects of relief valve,new electromagnetic cushioning and their co existence were compared and analyzed.It is found that the best cushioning effect is gotten when the two co exist,the new electromagnetic cushioning is second,and the traditional relief valve cushioning effect is not ideal.
