Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-2, a double-hanging-point type wave motion simulation test device comprises a simulated boat 1, a steel wire rope 2, a pulley 3, a frame 4, a hydraulic winch 5, a hydraulic pipeline 6, an electric control system 7, a pump station 8, an electro-proportional valve 9, an electromagnetic limit valve 10, a rotary encoder 11, an oil tank 12, an oil pump 13 and an electric control handle 14.
The lifting point distance and the weight of the simulated small boat 1 are consistent with those of a real boat. The simulated small boat 1 is connected with a winch through a steel wire rope 2 and a pulley 3. The pulley 3 and the winch are both arranged on the frame 4, the frame 4 is divided into two pairs, the left and the right pairs are fixed on the ground rail through high-strength bolts, and the ground rail is provided with an installation groove. The mounting bolts can move in the grooves, so that the center distance between the two auxiliary frames 4 can be adjusted conveniently to adapt to different boats. The winch is driven by a hydraulic motor and is connected with a pump station 8 through a hydraulic pipeline 6 to provide driving force for the winch. And a rotary encoder 11 is arranged on an output shaft at the tail end of the winch and used for detecting the movement direction and speed change of the steel wire rope 2 and transmitting the data to a PLC of the electric control system 7.
The electric proportional valve 9 is installed on the pump station 8, and hydraulic power is distributed through the electric proportional valve 9 so as to control the movement direction and speed of the winch.
In the 4-stage sea state, the speed change and direction of the wave motion are approximately sinusoidal, the maximum wave height is about 2M, and the maximum speed is about 100M/MIN. Therefore, the purpose of simulating wave motion can be achieved as long as the winch can drive the simulated boat 1 to achieve the maximum wave height and the maximum speed in a sinusoidal motion mode in the vertical direction through the steel wire rope 2.
When a wave motion simulation test needs to be carried out, firstly, a motor of the pump station 8 is started to supply oil to the hydraulic system. And setting the running speed and displacement parameters of the winch through a touch screen of the electric control system 7 according to the required sea condition grade. And then operating a wave simulation mode, wherein the electric control system 7PLC outputs continuously-changed current signals to the electro-proportional valve 9 to control the motion of a valve core of the proportional valve, hydraulic power output from the pump station 8 enters a hydraulic motor of the winch after flow is distributed according to programs through the electro-proportional valve 9 to control the positive and negative rotation and the speed of the winch, and at the moment, the simulated boat 1 performs simulated wave sinusoidal motion under the control of the steel wire rope 2. The motion signal of the winch is fed back to the PLC of the electric control system 7 through the rotary encoder 11 and compared with the set signal to carry out comparison operation, so that a closed loop is formed, and the precision and the stability of the control system are ensured. A limit electromagnetic valve is arranged beside the electro-proportional valve 9 and is used for controlling the lifting and descending limit of the winch and playing a role in safety protection. The up-and-down movement limit position of the simulated small boat 1 is set in the encoder, when the simulated small boat 1 touches and reaches the set position in the movement process, the encoder sends an instruction to the electric control system 7PLC, the PLC outputs a control signal to the limiting electromagnetic valve again, the electromagnetic valve is powered on, the winch stops rotating, and the device is prevented from being damaged by continuous movement.
The left winch and the right winch adopt the same control principle and adopt a hydraulic load sensitive control technology, and the output flow of the proportional valve only changes in proportion to the magnitude of an input current signal or the angle of a handle and is irrelevant to the magnitude of a load. The hydraulic pump also adopts load sensitive control, and when the handle of the electro proportional valve 9 is in a middle position, the pump only outputs a small flow. After the electro-proportional valve 9 leaves the middle position, the output flow of the hydraulic pump is in a proportional relation with the opening degree of the handle, no redundant flow is output, the heating of a hydraulic system is reduced, and meanwhile, the energy consumption is saved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
