Study on the Application of High Precision Strain Acquisition System Based on Twin-Constant-Current Source

Abstract:

Aiming at the shortcomings of the constant voltage source strain acquisition system, the paper put forward a new strain acquisition technology based on the double-side half-bridge measurement of the constant current source. It has demonstrated and analyzed the advantages of constant current source circuit using for strain collection, and has raised the design of multi-channel strain acquisition system. Lab test and running in a large fan blade deformation tests showed that the strain acquisition system had high measurement precision, stability, anti-interference and reliability.
