介绍了一种测量粘结磁体在室温至300℃下的抗压强度装置,通过实验确定了测量条件如标样形状、大小和保温时间,并对测量数据进行了误差分析,该方法的测量相对误差为±1.8%。
A device for measuring the compressive strength of bonded magnets at room temperature to 300 ℃ is introduced. The measurement conditions such as the shape, size and holding time of the standard are determined experimentally, and the error of measurement data is analyzed. The measurement of the method is relative The error is ± 1.8%.
