Embodiment Construction

[0039] Such as figure 1 As shown, a preferred embodiment of the present invention provides an anti-seasickness device based on a high static low dynamic vibration isolator, including a vibration isolator, which is set to have high static stiffness and low dynamic stiffness simultaneously, The high static stiffness is used to carry the weight of the human body, and the low dynamic stiffness is used to isolate the dizzying vibrations generated by the hull. The vibration isolator comprises a helical spring 1, and the helical spring 1 is installed between the vertical support part 5 arranged at the bottom of the seat 3 of the ship and the base 4 on the ship, and the seat 3 can move along the vertical direction under the support of the helical spring 1. move. According to different body weights and spring parameters, one or more coil springs 1 can be provided. In this embodiment figure 1 Only one coil spring is shown. If a plurality of coil springs are provided, the plurality o...

Abstract

The invention discloses a seasickness preventing method based on a high-static-rigidity low-dynamic-rigidity vibration isolator.The seasickness preventing method comprises the steps that step one, the high-static-rigidity low-dynamic-rigidity vibration isolator including spiral springs and flat spring groups, wherein the step one includes the sub-step of 1 arranging the spiral springs between vertical supporting portions at the bottoms of seats of a ship and bases on the ship, 2 machining first groove-shaped structures on the vertical supporting portions at the bottoms of the seats of the ship, machining second groove-shaped structures on the base supporting portions of the bases of the ship and installing the two ends of each flat spring group in the first groove-shaped structures and the second groove-shaped structures respectively; step two, the horizontal distances and the vertical distances between the first groove-shaped structures and the second groove-shaped structures are adjusted.The invention further discloses a seasickness preventing device based on the high-static-rigidity low-dynamic-rigidity vibration isolator.The seasickness preventing device and the seasickness preventing method are not only suitable for vertigo caused during ship navigation and can also prevent dizziness and discomfort of pilots and astronauts in the sky and outer space due to machine body vibration.

Description

technical field [0001] The invention relates to an anti-seasickness device and method, in particular to an anti-seasickness device and method based on a high static and low dynamic vibration isolator. Background technique [0002] Seasickness is a kind of motion sickness, which is caused by the stimulation of the vestibular nerve in the inner ear by various specific motion states when the car starts, accelerates and decelerates, brakes, ships shake, bumps, elevators and airplanes go up and down. , so that the hair cells in the vestibular apparatus produce deformation discharges, which are transmitted to the center and sensed. The generation and transmission of these vestibular electrical signals will not cause adverse reactions within a certain limit and time, but each person has a limit to the intensity and time tolerance of these stimuli. This limit is the stun threshold. If the stimulus exceeds This limit will cause symptoms of motion sickness. Under the same objective ...
