为了使检定者对冲击试验机有个比较全面的认识,这里概括地说明一下冲击试验机设计的最重要部分(从力学的观点看)——摆锤与度盘的设计:对于其它部分的设计属于一般的机械设计,在此不作叙述。4.1.1 摆锤的设计一、当设计摆锤时,首先给出所设计摆锤的冲击能E和摆轴到试样打击点的距离1(即到试样中心的距离),同时给出冲击速度v(根据试验方法或试验机标准确定)。例如JB30/
In order to give the examiner a more complete picture of the impact tester, the most important part of the design of the impact tester (from a mechanical point of view) is outlined here - the design of the pendulum and the dial: the design of the other parts Belongs to the general mechanical design, not described here. 4.1.1 pendulum design First, when the design of the pendulum, first of all given the design of the pendulum impact energy E and pendulum axis to the point of the sample hit points 1 (ie, the distance to the center of the sample), given the impact Speed v (according to the test method or test machine standard to determine). For example JB30 /
