A multi-sensor-based composite intervention guide wire performance detection system and method

Abstract

The application relates to the field of performance detection, and discloses a composite intervention guide wire performance detection system and method based on multiple sensors. The method comprises the following steps: performing an axial force test on a first sample to obtain an interlayer axial maximum static friction force; performing a rotary torque test on a second sample to obtain an interlayer torsional static friction force; respectively calculating a first interlayer bonding strength coefficient and a first torsional interlayer bonding strength coefficient, and comparing the two coefficients with preset standard values; if both the coefficients are qualified, outputting a comprehensive value; if any one is unqualified, performing a cyclic fatigue test on a third sample to calculate a second interlayer bonding strength coefficient; if the second interlayer bonding strength coefficient is still unqualified, performing a composite load test on a fourth sample and a fifth sample to respectively obtain calibration interlayer bonding strength coefficients in two sequences, and taking the average value of the two coefficients as a final result. Through a multi-stage evaluation strategy, the application realizes accurate detection of the bonding state of the inner and outer layers of a double-layer guide wire.
