Control system design of falling weight hydraulic buffer performance test-bed
Abstract
At present, the hydraulic buffers in high-speed, automated production line, in the engineering machinery, transport vehicles, as well as light industry, textile machinery on the hydraulic buffers have been widely used. Buffer to create a performance test of hydraulic test rig for testing the performance of hydraulic buffer is bound to have important significance
In this paper, the design of the test bed is falling weight test stand hydraulic buffer performance, and test-bed part of the control structure, work processes and circuit design are introduced. Test-driven mainly by an increase in the impact of the stepper motor block, adsorption and separation of the impact of the electromagnetic clutch block to collect a collision signal and block displacement sensors and the impact of increased rail screw component. After the collision, the data acquisition card collection procedures by the IPC to deal with measurement control information describing effective and displacement curve FS. The test-bed with internal hardware wear small, high-test safety factor, simple operation, the report details the characteristics of data.
