Ship tilt test pendulum bob reading system and accurate reading method

Abstract

The invention discloses a ship tilt test pendulum bob reading system and an accurate reading method, the ship tilt test pendulum bob reading system comprises a suspension support (1), a cycloid (2), a pendulum bob (3), an oil groove (4), a steel ruler (6) and an illumination headlamp (7), the suspension support (1) is fixed on a ship bulkhead, the upper end of the cycloid (2) is connected to the suspension support (1), the lower end is connected to the pendulum bob (3), and the oil groove (4) is filled with lubricating oil (5); the steel ruler (6) is fixed to the upper surface of the oil groove (4), and the lighting headlamp (7) is placed on the side face of the oil groove (4). According to the ship tilt test pendulum bob reading system and the accurate reading method, the problem of reading deviation caused by personnel visual angle difference is solved, the pendulum bob reading accuracy is improved, and the relatively dark working environment in the test reading process is improved.

Description

technical field [0001] The invention relates to a pendulum reading system and an accurate reading method for a ship inclination test. Background technique [0002] The ship inclination test is an effective method to obtain the actual weight and center of gravity of the ship after the ship is heeled. The ship weight and center of gravity measured and calculated by the test are the basic data for calculating the stability of the ship. It has a direct impact on the correctness of the calculation of the heel angle, and the inclination test plays an important role in the delivery of the ship and the future operation of the ship; using the hanging pendulum method to measure the heel angle of the ship is a commonly used method in the process of the ship inclination test. The specific operation Yes: choose a thin steel wire longer than 3 meters as the cycloid, bind a hanging hammer to one end of the cycloid, fix the upper end of the cycloid when in use, place the hanging hammer at t...

[0002] The ship inclination test is an effective method to obtain the actual weight and center of gravity of the ship after the ship is heeled. The ship weight and center of gravity measured and calculated by the test are the basic data for calculating the stability of the ship. It has a direct impact on the correctness of the calculation of the heel angle, and the inclination test plays an important role in the delivery of the ship and the future operation of the ship; using the hanging pendulum method to measure the heel angle of the ship is a commonly used method in the process of the ship inclination test. The specific operation Yes: choose a thin steel wire longer than 3 meters as the cycloid, bind a hanging hammer to one end of the cycloid, fix the upper end of the cycloid when in use, place the hanging hammer at the lower end in the water tank, and then adjust the swing width of the hanging hammer Place a steel ruler horizontally in the direction of the tilt test, and calculate the heel angle of the ship by reading the swing length of the hanging hammer. Moving with the cycloid, it is difficult for the human eye, the cycloid, and the scale line of the steel ruler to be on a straight line at all times, which will cause reading deviations due to differences in viewing angles, which will affect the accuracy of the test data
