用摆锤式冲击试验机进行冲击试验的过程中,影响材料冲击韧性的因素是多方面的。本文着重讨论摆锤冲击速度对材料冲击韧性的影响。一摆锤冲击速度计算 1 按能量守恒定律进行推导因摆锤在初始状态A位置的位能与摆锤冲击试样前那一瞬间的动能是相等的。所以根据能量学知道,摆锤冲击试样前那一瞬间的动能E_动(公斤-米)为:
Impact test using a pendulum impact test machine, the impact of material impact toughness of the many factors. This article focuses on the effect of pendulum impact velocity on the impact toughness of the material. A calculation of the pendulum impact velocity 1 According to the law of conservation of energy deduced because the pendulum in the initial state A position of the potential energy and the moment before the pendulum impact sample is equal to the kinetic energy. Therefore, according to the energy theory, pendulum impact sample that moment before the kinetic energy E_ (kg - m) as follows:
