A literature review of rollover test methodologies

Abstract

This paper presents a literature review of test methods that have been used to provide data for development of rollover occupant protection systems, including rollover sensor algorithms, test methodologies, and restraint-system performance. Test methods reviewed in this paper include SAE J2114, side curb trip, corkscrew ramp, critical sliding velocity, deceleration rollover sled, ditch/embankment, soil trip and various misuse tests. Historical development, procedure, application and the experience with these methods are discussed. Pros and cons of these test methodologies are summarised in relation to the rollover sensing algorithm and rollover occupant protection system development. Remarks related to test methodologies are made and issues pertaining to repeatability and dummy performance are discussed. Various component test methodologies are also reviewed and a newly developed component test device is presented. A brief review of CAE methodology and trends in test methods are also given.
