传感器支座振动对浮动缸套法测量结果影响

Floating-liner method provides an effective measurement mode to reduce the loss of piston friction. The principle of floating-liner method considers that piston friction force is the axial force of cylinder in the state of suspending by sensor support. However, vibration of sensor support and cylinder probably affects the measurement of sensor. This paper adopts single-degree of freedom hysteretic damping system under harmonic force to compare the output with the input, which obtains the measurement range and the influence factors of floating-liner principle. Changing three elements of vibration system can improve the accuracy of the sensor's measurement result ,which can perfect floating-liner method and provide theoretical direction for modification of floating device in the future.
