Description
Technical Field

Background
The marine gravimeter is a dynamic gravity measuring instrument which is arranged on a moving carrier such as a measuring ship and the like for continuous observation, can realize marine gravity measurement with high efficiency and large range, and provides high-precision gravity data for gravity-assisted inertial navigation, resource exploration and the like. When the marine gravimeter works, the marine gravimeter is influenced by vertical disturbance acceleration (noise) caused by sea waves in addition to gravity acceleration (useful signals). The acceleration period of the vertical disturbance caused by the sea waves is usually 6-10 seconds, and the amplitude under the condition of calm sea is about 15 gamma; under the general sea conditions of 2-3 levels of wind power and less than 1 m of wave height, the amplitude is about 80-100 gamma; and the amplitude can reach 200 Gal [7] under the severe sea conditions of 4-7 levels of wind power and several meters of wave height. The accuracy of the marine gravity measurement is usually 1 milligamma, so that the adverse effect of vertical disturbance acceleration on the measurement accuracy of the instrument needs to be overcome by adopting technical means such as strong damping and the like in the marine gravimeter. In order to obtain the best effect, the environment of the dynamic measurement of the gravimeter is often simulated by a vertical disturbance simulation device in the development process of the gravimeter to test the gravimeter.
The existing vertical disturbance simulation devices mainly have two types. One type is a swinging lifting platform, a platform is supported by a plurality of direct drive motors and a lead screw combination, and the platform vertically moves in a linear mode through cooperation of the motors. The device has the defects that the stroke is very limited, only the vertical disturbance with small amplitude value can be simulated when the marine gravimeter works, in addition, the device usually needs 8 direct drive motors and lead screws to act in a synergistic manner, and the cost is high.
The other type is an early developed device which utilizes a three-phase motor to provide power, realizes the rotation speed regulation through a gearbox, and converts the rotation motion of the motor into reciprocating linear motion by utilizing a crank block mechanism. The disadvantages of such devices are as follows: 1. a two-stage gearbox and a crank sliding block mechanism need to be arranged, and the structure is complex; and only depends on several gear ratios of the gearbox to simulate several disturbance characteristics (amplitude and frequency) with very limited number, and the application range is narrow; 2. the simple gimbal mounting mode leads the gravity meter to be inclined easily in the reciprocating linear motion process, thereby introducing errors; 3. the gradient of the laboratory environment temperature in the vertical direction is large, and the output result of the gravimeter is obviously influenced by the temperature when the amplitude of the linear reciprocating motion is large.
