COMBINED EFFECT OF FRICTIONAL AND ELASTIC MOMENT AGAINST TRUCK TURNING ON RUNNING STABILITY OF A TRUCK WITH ELASTICALLY SUSPENDED AXLES

The Frank-Koenig's method is used to search for a criterion of stability for polynomials with complex coefficients. It is made clear that the turning stiffness of truck, the friction of side bearers, the supporting stiffness of axles, the slope of wheel treads and the creep coefficients between wheel and rail, have effects on the truck hunting. According to these results, the optimum value of the longitudinal supporting stiffness of axle and that of the lateral one to give the maximum speed of hunting are concerned with the magnitude of the turning amplitude of the truck on the hunting.
