摘要
Abstract
In order to solve the problem of lacking theoretical support when we choose accumulators in the return system of fast forging hydraulic units,the dynamic analysis and the experimental research on dynamic characteristics are put forward.We take the return system of 10 MN fast forging hydraulic units as an example.We build simulation models with bladder accumulator and piston accumulator respectively by using the software AMESim.The simulation results show that the forging frequency of the fast forging hydraulic unit return system with piston accumulator is 1.2 times faster than that of the return system with bladder accumulator;the response time of the fast forging hydraulic unit return system with bladder accumulator is 20 ms less than that of the return system with piston accumulator in the return stroke of return cylinder;however,when the host is pressing down,the response time of the return system with bladder accumulator is 100 ms behind that of the return system with piston accumulator.And the inlet flow of return cylinder in the return system with bladder accumulator has larger fluctuations.Through different initial inflation pressures and different accumulator volumes,the fast back-press system with piston accumulator is tested on the premise of meeting the fast forging press return pressure.The conclusions of simulation and measured results are always the same.关键词
