Tripped rollover results when a vehicle slides sideways into a curb or other small obstruction which converts the vehicle's translational kinetic energy into rotation. Given the vehicle's center of gravity height and wheel track width, it can roll over given sufficient side velocity. The scenario is applicable to highway vehicles such as cars and trucks and off road vehicles as diverse as riding lawn mowers. Safety statistics show vehicle rollover to be a common accident mode, and the report describes a time domain simulation program developed to analyze the influence of various vehicle and scenario parameters. The program is based on a general purpose microcomputer program which was designed to simulate dynamic systems defined in relatively simple specification syntax, and provide the user with insightful graphical displays. The program currently runs on an IBM-PC or compatible. The report describes the vehicle model equations of motion, provides program user's instructions, and gives examples of program operation.
