Through the embodiment of the utility model provides a process that pendulum mass horizontal impact experimental apparatus assaults the experiment includes:
a user issues a pendulum bob 2 swinging instruction, an electrical system enables the second overflow valve 27 to be electrified, oil enters an oil inlet of the double-piston-rod hydraulic cylinder 25, the first brake piece 23 and the second brake piece 24 are respectively pushed away outwards by two piston rods in the double-piston-rod hydraulic cylinder 25, and the rotating shaft 1 is loosened. Then, the electrical system opens the first solenoid valve 21 and the second solenoid valve 22, closes the first relief valve 17, and the hydraulic oil enters the first cavity 31 from the first oil passage 29. The pressure in the first cavity 31 is the same as the pressure in the pipeline of the first cavity 31, and both are in a pressurized state. Since the second oil through port 30 is directly connected to the oil pump 16 and the oil tank 20, the pressure in the second cavity 32 and the pressure in the second oil through port 30 line are always at normal pressure. At this time, since the pressure in the first cavity 31 is greater than the pressure in the second cavity 32, the vane 15 is pushed to rotate toward the second cavity 32. Since the blades 15 are integral with the shaft 1, when the blades 15 are rotating, the shaft 1 also rotates. The rotating shaft 1 is rigidly connected with the swing arm 3, the swing arm 3 is rigidly connected with the pendulum bob 2, and the pendulum bob 2 is driven to swing when the rotating shaft 1 rotates. When the vane 15 rotates toward the second cavity 32, the space of the second cavity 32 is compressed, and the hydraulic oil in the second cavity 32 flows into the oil tank 20 from the second port 30, as shown in fig. 6.
Since the angle sensor 4 is installed on the rotating shaft 1 concentrically with the rotating shaft 1, the angle sensor 4 can synchronously transmit the collected angle data to the electrical system when the rotating shaft 1 rotates. When the current angle monitored by the angle sensor 4 reaches the set angle, the electrical system enables the second overflow valve 27 to be de-energized, hydraulic oil in the double-piston-rod hydraulic cylinder 25 directly flows into the oil tank 20 through the third oil outlet pipeline 28, the double-piston-rod hydraulic cylinder 25 is de-energized, the spring pulls the first brake piece 23 and the second brake piece 24 to move oppositely, the rotating shaft 1 is locked, and the pendulum bob 2 stops swinging. Meanwhile, the first overflow valve 17 is powered on, the hydraulic oil in the first cavity 31 directly flows into the oil tank 20 through the first oil outlet pipeline 18, the first cavity 31 is depressurized, and the rotating shaft 1 has no driving force.
After the process, the pendulum bob 2 reaches a designated angle, the rotating shaft 1 has no driving force, and the hydraulic brake 13 locks the pendulum bob.
And a user sends an impact instruction, the electrical system enables the second overflow valve 27 to be electrified, the oil inlet of the double-piston-rod hydraulic cylinder 25 is filled with oil, the two piston rods in the double-piston-rod hydraulic cylinder 25 push the first brake pad 23 and the second brake pad 24 outwards respectively, and the rotating shaft 1 is loosened. The pendulum bob 2 takes the rotating shaft 1 as a center, converts self potential energy into kinetic energy impacting downwards, and swings through inertia to achieve the purpose of impacting.
The first overflow valve 17 is powered, the hydraulic oil in the first cavity 31 directly flows into the oil tank 20 through the first oil outlet pipe 18, the pressure of the first oil through port 29 is in a normal pressure state, and the pressure in the second cavity 32 and the pressure in the second oil through port 30 are always in a normal pressure state because the second oil through port 30 is directly communicated with the oil pump 16 and the oil tank 20. At this time, the pressure in the first cavity 31 is equal to the pressure in the second cavity 32, and the blade 15 is subjected to a force of 0. The rotating shaft 1 is driven by the pendulum bob 2 to rotate reversely, and simultaneously, the blades 15 also rotate reversely along with the rotating shaft 1. At this time, the volume of the first cavity 31 is reduced, and the hydraulic oil in the first cavity 31 flows into the oil tank 20 from the first oil passage port 29. Meanwhile, the volume of the second cavity 32 is increased, and the hydraulic oil is filled into the second cavity 32 from the second oil through hole 30, as shown in fig. 7.
After a shock test, the pendulum bob 2 and the impact surface 10 are in rigid collision to generate rebound, when an electrical system monitors that the angle is reduced, a contracting brake command is issued immediately to ensure that the second overflow valve 27 is de-energized, hydraulic oil in the double-piston-rod hydraulic cylinder 25 directly flows into the oil tank 20 through the third oil outlet pipeline 28, the double-piston-rod hydraulic cylinder 25 is de-pressurized, the spring pulls the first brake piece 23 and the second brake piece 24 to move oppositely, the rotating shaft 1 is locked, the pendulum bob 2 stops swinging, and secondary shock is effectively prevented.
