摘要
借助于电阻应变式称重传感器在恒定负荷作用下的蠕变模型,探讨了蠕变误差补偿机理及其可行的技术方案,提出了通过改变敏感栅端部的受力状况来改变应变片蠕变值的蠕变补偿思路,试验证明是可行的.
With the aid of the creep model of a resistance strain gauge load cell underconstant stress, the mechanism and the feasible technical scheme of creep error compen-sation are studied in this paper. A thinking for creep compensation that the creep valueof a strain gauge may be changed by means of change of the stress state at the end ofstrain gauge grid is put forward and is confirmed experimentally to be feasible.
