Liquid-filled Passive Color Changeable Sensor for Monitoring Axial Force of Rock Bolt

摘要

摘要: 设计了一种锚杆轴向力充液式无源变色传感器。利用敏感材料在不同形变下传感器显示不同颜色的特点来检测锚杆轴力情况。通过ANSYS对整体可行性进行流固耦合力学仿真并统计敏感材料截面多节点应力来分析颜色均匀特性;对传感器进行压力-颜色关系试验,并分析温差和偏载的影响程度。结果表明:该传感器在不同压力下显示不同颜色,且颜色均匀,易于观测;偏载距离在5 mm内与温差在0~20 ℃时,对传感器颜色均匀性和灵敏度无影响。

Abstract: A liquid-filled passive color changeable sensor for bolt axial force is designed. In order to detect the axial force of the bolt, the characteristics of different colors of the sensor under different deformation of the sensitive material is used. ANSYS is used to carry out the fluid-solid coupling mechanical simulation of the whole feasibility and calculate the multi-node stress of the sensitive material section to analyze the color uniformity; the relationship tests of pressure and color are conducted for the sensor, and the influence degree of temperature difference and partial load is analyzed. The results show that the sensor can display different colors under different pressures, and the color is uniform, which is easy to observe; when the partial load distance is within 5 mm and the temperature difference is 0 to 20 ℃, the temperature difference and partial load have no effect on the color uniformity and the sensitivity of the sensor.
