[0034] The present invention will be further described now in conjunction with accompanying drawing:
[0035] Sensor Quantity Optimization Method
[0036] Suppose the measuring range of the instrument is A and the precision is η, then the absolute error limit is A×η. The formula for calculating the peak signal-to-noise ratio threshold P is: P = 10 log 10 ( a Sig 2 / a Noi 2 ) , In practical application, P can be obtained from instrument precision statistics.
[0037] Obtain the minimum acceleration peak value of the signal:|a min |≥A×η×10 0.05P
[0038] According to the modified Timoshenko beam theory, the lateral motion of the beam can be expressed as
