Types of vehicle rollovers can be classified into two categories:​ untripped and tripped. Untripped rollovers are relatively rare events resulting from high lateral friction forces between the tires and road. Tripped rollovers are the result of lateral forces caused by the tire or wheel digging into the road or ground or from striking a curb or other obstacles. As reported in the open literature, various test methods for conducting rollover events such as SAE J2114, Side Curb Trip, Critical Sliding Velocity, and Corkscrew have been used. This paper presents the development of MADYMO-based models for simulating vehicle kinematics in these four modes. The CAE methodologies using MADYMO is interactively developed with the test methodologies. Experimental data obtained from these test modes are used for developing rollover CAE models for replicating vehicle motions under similar test conditions. Analyses of simulated results provide feedback to improve the test procedures. Testing with improved procedures provide additional new data for continued model refinements. MADYMObased CAE tools thus provide quality models with better simulated and/or predicted results. MADYMO rollover models consist of sprung and un-sprung masses, suspension systems and tires, whose characteristics are extracted from ADAMS-based vehicle handling model. Use of the MADYMO-based models to support rollover testing, rollover sensing algorithm development, and rollover protection system development will be described. Since MADYMO modeling described in this paper is a rigid-body based approach, model limitations and issues associated with rollover simulation will also be discussed. In addition, model correlations with test data in these four modes and future areas of improvement will be presented.
