冲击试验用于考察材料的脆性或韧性。它对材料的质量(内部缺陷、工艺质量等)、材料随温度改变而出现的脆性转化很敏感,能显示材料内部组织结构的微小差异。所以,冲击试验在各工业部门得到广泛的应用。我厂在生产中使用的冲击试验机是一台36/15摆锤式三用冲击试验机,它是由长春仪器厂在1956年制造的。该试验机分两个能量级,即:36公斤·米和15公斤·米。打击能量的改变,依靠摆锤预扬角的大小实现。为了确定该设备的检验价值,我们进行了摆锤冲击速度对
Impact test is used to investigate the brittleness or toughness of the material. It is sensitive to the quality of the material (internal defects, process quality, etc.) and to the brittle transformation of the material as the temperature changes, showing minute differences in the internal organization of the material. Therefore, the impact test in various industrial sectors have been widely used. I plant used in the production of impact testing machine is a 36/15 pendulum three-way impact testing machine, which is manufactured by the Changchun Instrument Factory in 1956. The test machine is divided into two energy levels, namely: 36 kg · m and 15 kg · m. Strike energy changes, relying on the size of the pendulum pre-Yang realized. In order to determine the test value of the equipment, we conducted a pendulum impact velocity pair
