Description

Technical Field

[0001] This utility model relates to devices in the field of marine mechanical equipment measurement technology, and in particular to a device for measuring the deformation and flatness of a vibration damper. Background Technology

[0002] Mechanical vibration is an unavoidable problem during shipbuilding. Vibration consumes system energy, causes unnecessary energy loss, reduces mechanical efficiency, and in severe cases, can even damage equipment, leading to economic losses and major safety accidents. Vibration dampers, as the channel for vibration transmission between equipment and the hull, directly affect the transmission of equipment vibration during navigation and are an important means of controlling mechanical equipment vibration noise. As the primary means of suppressing equipment vibration transmission, the measurement of the deformation and flatness of vibration dampers is particularly important.

[0003] Currently, my country's research and development of vibration dampers is progressing rapidly, with the development of a series of vibration dampers possessing excellent damping effects and impact resistance, which have been widely applied in the shipbuilding industry. However, the deformation and flatness of vibration dampers directly affect their installation quality and efficiency. Since domestic shipyards have not yet implemented such pre-installation measurements, the installation efficiency is low, and this also restricts the quality of low-noise installation. Therefore, how to effectively measure the deformation and flatness of vibration dampers before installation to improve the pass rate of vibration damper positioning and installation has become an urgent problem to be solved. Utility Model Content

This device uses a driver to manipulate a loading beam to apply load to the vibration damper, and then collects the changes in force and displacement sensors through a data acquisition unit, thus solving the technical problem that traditional methods cannot effectively measure the deformation and flatness of vibration dampers.

[0005] The solution adopted by this utility model to solve the technical problem is:

[0006] A device for measuring the deformation and flatness of a vibration damper includes an execution system and a control system. The execution system includes a base, arranged on a horizontal construction site for installation and support; loading columns, one end fixed to the upper part of the base and the other end extending vertically upward, arranged in pairs with grooves on opposite side walls; a loading beam, assembled between the two loading columns, with its left and right ends able to slide synchronously up and down within the grooves of the loading columns; a loading disk, assembled at the lower part of the loading beam; a force sensor, fixed to the lower surface of the loading disk; a displacement sensor, assembled on the front side wall of the loading disk; and a loading bracket, fixed to the upper surface of the base and correspondingly arranged below the loading disk. The control system is connected to the execution system via wires to apply load to the vibration damper and synchronously receive data on the changes in vibration damper values.

[0007] The control system disclosed in this embodiment includes a display console, which is disposed on the side of the base; a drive unit, one end of which is connected to the loading beam and the other end of which is connected to the display console, for driving the loading plate to apply load to the vibration damper; and a data acquisition unit, one end of which is connected to the force sensor and the displacement sensor, and the other end of which is connected to the display console.
