The invention relates to the technical field of accelerometers, and discloses an anti-vibration accelerometer which comprises a fixed base and an accelerometer body; a through opening is formed in themiddle of the upper surface of the fixed base, a first groove is formed in the left side of the inner top wall of the fixed base, and a buffer rod is fixedly connected to the top wall of the first groove. According to the anti-vibration accelerometer, when the accelerometer vibrates due to external factors, the accelerometer body can vibrate up and down in the fixed base, and when the accelerometer body moves upwards, the first damping spring can bear pressure to generate damping elastic force so as to reduce the upward movement amplitude of the accelerometer body; when the accelerometer bodymoves downwards, the supporting column moves downwards, at the moment, the second damping spring is pressed to generate upward damping elastic force, the amplitude of downward movement of the accelerometer body is reduced, the amplitude of up-and-down vibration of the accelerometer body when the accelerometer body is vibrated is greatly reduced, and the shock resistance of the accelerometer is improved.
Description
technical field [0001] The invention relates to the technical field of accelerometers, in particular to an anti-seismic accelerometer. Background technique [0002] The accelerometer is an instrument for measuring acceleration. When an object has a large acceleration, the object and its equipment and other objects without relative acceleration are subjected to a force that can produce the same large acceleration, that is, a dynamic load. To know The dynamic load needs to measure the acceleration. Secondly, it is necessary to know the spatial position of each instantaneous aircraft, rocket and ship. The acceleration can be continuously measured through inertial navigation, and then the velocity component can be obtained through integral calculation, and the position in one direction can be obtained by integration again. Coordinate signals, and the measurement results of the three coordinate directions of the instrument will synthesize the motion curve and give the space posit...
