system of the tuning fork are studied experimentally. The experimental results have shown that the square of
the period is proportional to the area of the damping plate under the same shape. Damping plate with the same area
and different shapes have different resonance frequencies and sensitivities. The sensitivity of the rectangle is larger，
and the sensitivity of the triangle is smaller. The resonance frequency of forced vibration of the tuning fork is related
to the fixed position and the angle of the damping plate with the same shape and area. The result obtained in this research
is certain guiding to the design of tuning fork sensor.
