图1表示高速拉伸试验装置的结构,主机是在木制箱形板的中央装一杠杆,用弹簧缓冲器连结在杠杆的下方。用手柄将杠杆扣接于卡锁内,夹好试样,松开卡锁,弹簧力即将试样拉伸,直到破坏为止。这时的拉伸速度是由一个节流阀来控制,对于出现在试样上的最大行程为10毫米来说,其时间为10秒至0.1秒。试样的有效长为100毫米,宽为2毫米。 Fig. 1 shows the structure of a high-speed tensile test apparatus in which a lever is mounted on the center of a wooden box plate and a spring damper is attached below the lever. Handle the lever buckle in the card lock, clip a good sample, release the latch, the spring force is about to stretch the specimen until the damage so far. The stretching speed at this time is controlled by a throttle valve, which takes 10 seconds to 0.1 seconds for the maximum stroke of 10 mm appearing on the specimen. The effective length of the sample is 100 mm and the width is 2 mm.
