The utility model principle of work:
The utility model utilizes quartz flexible accelerometer output formula U=Ksin θ+A
0For foundation is carried out calibration; As shown in Figure 9; Test result according to two position A of symmetry, B (corresponding to the position of two blocks of side plates of the utility model) is that angle is by just becoming negative relation; The output U of angle 2 θ between the known symmetric position and two positions of symmetry just can obtain the parameter that needs calibration: zero A partially
0With constant multiplier K.
(θ+β)+A can know that the accuracy of constant multiplier K is relevant with the deviation angle β of fixed angle θ, center line and gravity vertical according to formula U=Ksin.The variation of fixed angle θ is bigger to the influence of measurement result, and the utility model has taked a series of measure to reduce the influence of θ to measurement result, and concrete measure is following:
