3.1 Impact moving body
Install the anvil of the accelerometer.
3.2 Differential grating laser interferometry
When a single frequency of laser light is incident on the moving diffraction grating plane, the diffracted light of different orders is produced differently.
Puls frequency shift, taking any two-order diffracted light as the measuring beam to interfere, the frequency of the differential signal and the motion of the grating
Speed is a simple linear relationship. The method of measuring the velocity of an object using this scheme is called differential grating laser drying.
Involved in the law.
4 Overview
Impact accelerometers are widely used in the measurement of impact. Commonly used impact accelerometers are piezoelectric or piezoresistive. Number
The learning model can be simplified to a single degree of freedom second-order system.
Mx′′ cx′ kx=f(x)
Where. m, c, k --- equivalent detection quality, damping, stiffness;
x′′,x′,x—the acceleration, velocity, and displacement acting on the equivalent mass;
f(x)---external force.
