The difference between the acceleration setting value and the actual value when the centrifuge is rotating at a constant speed:
The difference between the acceleration setting value and the actual value when the centrifuge is in the working state of non-uniform speed rotation:
Within the rated speed range, the maximum acceleration rate that the centrifuge can achieve:
4 Overview
The centrifuge is mainly composed of a rotating body that rotates around the rotary axis, a speed stabilization system, an accelerometer installation and positioning, and a center of mass alignment system:
system and data acquisition and processing system: Driven by the motor, the working platform (or cantilever) rotates around the axis of rotation
When the angular velocity of the centrifuge is ω, the radial acceleration generated by the centrifuge at the working radius R is: a=ω2R, the acceleration
Velocity is the standard acceleration that the centrifuge reproduces:
The high dynamic precision centrifuge can change the acceleration by changing the rotation angular rate ω, which is mainly used for acceleration
Inspection of performance indicators such as linearity (non-linearity), high-order coefficients (second-order, third-order, etc:), hysteresis error, etc: of the speedometer
determination, calibration or testing:
When calibrating a high-dynamic precision centrifuge, the steady-state acceleration indication error and the variable acceleration indication error are mainly considered:
Difference and acceleration maximum rate of rise and fall and other characteristics:
5 Metrological characteristics
The metering characteristics of the high dynamic precision centrifuge are shown in Table 1:
