Abstract:

A microcomputer-controlled ultrasonic Automated Depot Roadwheel Inspection System was reprogrammed to incorporate a mathematical model for estimation of the adhesion strength of the rubber-to-metal bonding based on selected ultrasonic parameters. Additionally, acceptreject criteria for weak bonding and undercure were modified along with certain characteristics of the microcomputer control of the hardware of the system. A 6-month field test was run with this modified configuration to assess the correlation of the ultrasonic inspection system predictions of roadwheel quality determined by in-production destructive testing. The success of adhesion failure prediction in this test is discussed, along with the need for further data analysis for enhanced strength prediction and hardwaresoftware modifications to allow reliable separation detection. Keywords Ultrasonic tests Nondestructive testing Composite materials.
