摘要:
本文对电阻应变式测力仪接桥方法与电桥灵敏度的关系进行了理论分析及试验研究。证明测力仪与不同应变仪联接时,电桥接桥方法对电桥的灵敏度有着不同的影响。对于 JD-1、YJ-5及 Y6D-2等型号的应变仪,电桥各工作桥臂上应变片的串联或并联不影响电桥的灵敏度;而对于 Y6D-3A 及 Y8DB-5等型号的应变仪,电桥各工作桥臂上应变片的片数、串联或并联都对电桥的灵敏度有着显著影响。在等臂全桥的情况下,每一工作桥臂由 n 片应变片并联时,其电桥的灵敏度为串联时的 n 倍。
Abstract:
In this paper,the relationship between bridge connections and sensitivity of strain gauge dynomolneters has been investigated with the results verified by experiments.Investigations show that different bridge connections have diffe- rent effects on sensitivity of bridge when dynomometer is connected with di- fferent strain gauges.For strain gauges types YJD-1,YJ-5 and Y6D-2,gauges on active arms either in series or in parallel show no effect on bridge sensi- tivity;for strain gauges types Y6D-3A and Y8DB-5 both number of gauges and connection in series or in parallel on active arms affect the sensitivity consi- derably. For the four-arm bridge where each active arm consists of n gauges in para- llel the sensitivity is n times that in series.
