摘　　要：为了了解不同原理、不同厂家传感器的准确度。试验采用简支梁并用水进行分级加载的方式对应力进行测量,通过测量的数据对几种传感器的试验结果进行对比研究。试验表明,电阻应变片比振弦式传感器测量应力的准确度高。In order to understand the different principle and manufacturer the accuracy of the sensor,measured stress with the method of simply supported beam and graded loading with water,comparative studied the test results of several kinds of sensors. The tests indicate that resistance strain gage had the higher accuracy than vibrating wire transducer to the measurement of stress.

关 键 词：简支梁 应变片 振弦传感器 应力
