摘要:
The disclosed embodiment is an extensometer to measure transverse strain with a passive vertical system making use of a linear optical encoder. The sensor arms are mounted on respective carriages which traverse on respective linear tracks. The carriages are spring-loaded so as to bias the sensor arms toward a closing direction. In order to separate the sensor arms and act against the force of the springs, the carriages are responsive to or pushed by upper and lower drive brackets which are affixed to respective upper and lower portions of a looped timing belt. The extensometer makes use of a low-friction design to minimize rolling friction in the movement of the two sensor arms. One carriage includes an encoder read-head which directly faces an encoder scale on the other carriage. In this configuration, the exact relative position of the two carriages, and hence the two sensor arms, can be read.
摘要(中):
所公开的实施例是使用线性光学编码器的被动垂直系统来测量横向应变的引伸计。 传感器臂安装在相应的托架上,横列各自的线性轨迹。 托架是弹簧加载的,以便将传感器臂朝着关闭方向偏置。 为了分离传感器臂并抵抗弹簧的作用力,滑架由上和下驱动支架响应或推动,上和下驱动支架固定在环形同步带的相应上部和下部。 引伸计使用低摩擦设计来最小化两个传感器臂的运动中的滚动摩擦。 一个托架包括编码器读头,其直接面对另一托架上的编码器刻度。 在这种配置中,可以读取两个滑架以及因此两个传感器臂的精确相对位置。
