Terfenol-D传感器在不同工作条件下的输出力-应变关系的典型性能进行检查，研究传感器阻塞力特性。本文介绍了一种在受控的热、磁和机械载荷条件下进行测试的传感器的设计和结构。在不同的外加磁场和两个初始机械应力状态下的压缩测试结果被用来生成负载线和传感器的阻挡力特性。传感器的力和应变输出的比较与公布的数据。该测试数据还用于检查杨氏模量随施加的磁场、应变和应力的变化。
The output force-strain relationship typical of the performance of Terfenol-D transducers under varied operating conditions is examined to study transducer blocked force characteristics. The design and construction of a transducer for testing under controlled thermal, magnetic and mechanical load conditions are described. Results of compression tests at various applied magnetic fields and two initial mechanical stress states are used to generate load lines and the blocked force characteristics of the transducer. Comparisons of the transducer's force and strain output are made with published data. This test data is also used to examine the variability in Young's Modulus with applied magnetic field, strain and stress.
