拉力试验机的力值计算方法


  平时大家都注意过拉力的烦力值计算问题,大家也都知道拉力试验机是测试材料拉伸性能最好的设备,那拉力试验机带地怎么测试材料的性能又是怎么计算力值的呢?
拉力试验机力值的核算是依据试验机被检区间的力值,将响应力值的规范拉力试样装夹在试验机上,按GB/T228-2002规范规则的速度让试验机对规范拉力试样进行拉伸,当规范拉力试样处于拉伸形态时在其上装上引伸计或贴上应变片,让拉力试验机持续对规范拉力试样进行拉伸,引伸计或应变片将规范拉力试样的伸长量显示出来,将伸长量换算为拉力值,再与拉力试验机度盘上与规范拉力试样一样的力值点进行比照,依据比对值的差来确定试验机技能形态及精度。
此办法应用胡克定律,依据规范拉力试样的伸长量换算为力值与试验机度盘力值进行比照,来确定试验机的精度。该办法极大的简化了检定的操作进程。
