| Abstract: | The internal dynamic load on a high-speed car following a real rail track with curvature and torsion is evaluated. The centrifugal, gyroscopic, tangential, and Coriolis forces and moments are taken into account. The kinematical parameters were obtained experimentally using an inertial system similar to that used to control space-rocket systems. The Euler-Lagrange equations represented by quaternionic matrices are used to determine the unknown dynamic loads in an explicit analytical form, which makes it possible to evaluate the components of dynamic loads due to the forces and moments acting on the car__________Translated from Prikladnaya Mekhanika, Vol. 41, No. 3, pp. 119–126, March 2005. |
