Paper Abstract

The winding system has a long travel range, often reaching several meters or even hundreds of meters. Conventional long-range displacement measuring methods have a large measurement error and are difficult to realize bidirectional measuring. An innovative long-range automatic displacement measuring method and device of winding system is proposed and designed, which uses double timing belt transmission pairs as precise clamping conveyer. By analyzing the displacement error of linear transmission caused by the polygon effect of trapezoid tooth and circular arc tooth, this paper proposes to use circular arc tooth timing belt to reduce the measurement error. Double rotary encoders are used to measure the displacement simultaneously, which can effectively reduce the measurement error caused by the slippage of the timing belt transmission. The proposed method and device has been used successfully in cable displacement measurement of trailing cone automatic retracting and releasing system for air static pressure measurement in aircraft test flight. The experimental results show that the proposed method is correct and feasible, and the displacement measurement error is less than 0.5%.
