仪表工业中,具有各种特殊性能的弹性合金带材被大量用来制造弹性敏感元件。不论在何种仪表中,人们总是希望弹性敏感元件的变形能足够带动仪表的传动机构,并且具有小的迟滞、长的寿命和尽可能不受温度的影响等等。因此,对于制造弹性敏感元件的材料,就有了不少相应的特殊要求。如希望材料具有一定弹性模量值,尽可能高的弹性极限和疲劳极限。在弹性敏感元件制造中,就有人提出材料的σ_e~2/E比值问题[6]。
In the instrumentation industry, flexible alloy strips with a variety of special properties are used in large quantities to make elastic sensing elements. No matter what kind of instrument, people always hope that the deformation of the elastic sensing element can drive the instrument driving mechanism enough, and has little hysteresis, long life and is not affected by temperature as much as possible and so on. Therefore, there are quite a few corresponding special requirements for the materials used to make the elastic sensor. If the material is expected to have a certain modulus of elasticity, as high as the elastic limit and fatigue limit. In the manufacture of flexible sensing element, some people put forward the material σ_e ~ 2 / E ratio problem [6].
