WebA proof mass or test mass is a known quantity of mass used in a measuring instrument as a reference for the measurement of an unknown quantity. A mass used to calibrate a weighing scale is sometimes called a calibration mass or calibration weight. A proof mass that deforms a spring in an accelerometer is sometimes called the seismic mass. In a … WebNatural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving force.. The motion pattern of a system oscillating at its natural frequency is called the normal mode (if all parts of the system move sinusoidally with that same frequency).. If the oscillating system is driven by an external force at the …

Webproof mass has a great impact on the value of natural frequencies and distribution of strain along the beam. Tang & Wang [12], proposed an analytical method to calculate the natural frequencies of ... WebThe traditional designs of inertial sensors involve a solid proof mass or rotation part , which have some disadvantages such as low life , low reliability , difficult manufacturing and high cost 目前商用的惯性传感器一般需要检验质量块或者旋转部件，因此，器件的寿命短、可靠性低、加工困难且成本较高。 Webmechanical force on the proof-mass. Here, we will not consider these dynamics. Rather, designs will be chosen which avoid this condition, due to the damage caused to the proof-mass and the high-frequency shocks imparted on the structure resulting from the collision of the proof-mass with the actuator base.
