Research on Straightening Force Measuring Technology for Pre-stress Straightening Machine

摘要

This paper introduces the hardware components of the straightening force measuring system for the pre-stress straightening machine firstly. Then finite element analysis is made for the frame of pre-stress straightening machine based on ANSYS Workbench. Relationship between the straightening force and relative strain on the column neutral layer is obtained by using polynomial fit. And this relationship is used to obtain straightening force in the DAQ software. Then the straightening force DAQ software is developed based on LabVIEW. Structure and development process of the software are introduced in details at last.
