A mathematical model for sideways overturning performance of tractor and trailer combinations

Abstract A mathematical model for sideways overturns of wheel-tractor and trailer combinations, by the conventional method of disassembly and assembly of system components supplemented with a method of energy symmetry, devised for the present purpose to take care of the singularity range of the roll angle, was developed with a corresponding digital computer program and verified with tests on a 1/4.5 scaled, self-powered remote-controlled test model with agreeable results.
