Torque Performance Measurement System for Spring in Seat Belt

Abstract:

To acquire torque performance in seat belt conveniently and precisely, the measurement scheme based on stepper motor was established. The hardware was developed with high-speed data acquisition unit based on PCI protocol. The software which includes user interface and data acquisition control module etc was developed with multithread technique and document-view architecture. The experiments with seat belt spring show that the max torque error of the system is 0.08N.cm. The system has merits of high precision, easy operation and can provide reliable data for spring torque performance in seat belt.
