N2 - According to the clamped-clamped structure of DN1 Coriolis mass flow sensor, the static deflection curve of the measuring tube with driving force and the torsion strain curve of the tube with Coriolis force are derived by force method. The equivalent elastic rigidity of the measuring tube calculated from the static deflection curve can be used to derive the resonant frequency. The maximum sensitivity and its location can be calculated from the torsion strain curve, which provides an important theoretical basis for the location optimization of the detection point. The resonant frequency and the sensitivity of DN1 Coriolis mass flow sensor are analyzed by the finite element analysis software ANSYS. By comparison, the result of theory analysis coincides exactly with ANSYS simulation, which provides an important theoretical basis for the sensor structure optimization.
