本文涉及到我们在改进力传感器性能所遇到的几个问题。这些问题归结为以下三类情况。(1)材料(2)结构与制造(3)应用与校验。 第一类问题中,在对弹性材料和应变计材料进行透彻研究后,我们必需着重强调滞后性能。如改进用应变计表示的精度。我们采用俗称“BI—SELCOM”的有效技术。在第二类问题中,力传感器结构的稳定性和生产工艺需要引起我们极大注意。弹性材料都要经热处理,应变计应温度老化处理后方能达到长期稳定性。在最后一类问题中,要求包括大称量力传感器方面类似实际使用环境的校验及高精度校验。 This article addresses several issues we have encountered in improving the performance of force sensors. These problems fall into the following three categories. (1) Materials (2) Structure and Fabrication (3) Application and Verification. In the first of these questions, after thoroughly studying the elastomeric and strain gauge materials, we must emphasize lag performance. Such as improving the accuracy of the strain gauge. We use the so-called “BI-SELCOM” effective technology. In the second type of problem, the stability of the force sensor structure and the production process need our attention. Elastic materials are subject to heat treatment, strain gauges should be aged after aging to achieve long-term stability. In the last category of questions, requirements include calibrations and high-precision verifications that are similar to the real-world use of large force sensors.
