... three-dimensional motion of the car bodies and captures kinematic degrees of freedom that are not captured using existing simpler models. The coupler kinematic equations are expressed in terms of the car body coordinates, as well as the relative coordinates of the coupler with respect to the car body...

...Jenchieh Lee; Henryk Flashner; Jill L. McNitt-Gray A method for the estimation of kinematics of a system of rigid bodies connected by three degrees of freedom rotational joints using position measurements is introduced. In the proposed approach, system kinematics are computed from experimental...

... and reduce the noise generation. In this paper, a kinematic and a geometric model of a bent-axis pump have been created as part of a complete dynamic model. The other elements of the complete dynamic model that are not discussed in this paper include finding the variation of piston pressure, flow rate...

... continuous and hybrid dynamical systems. The results presented require only velocity-level kinematics to form the Lagrangian and find equilibrium configuration(s) for the system. A set of selected partial derivatives of the Lagrangian are then computed and used to directly construct the linearized equations...

... tasks with comparably small deflections and simple kinematics. They are not directly applicable to the difficult development process of large motion mechanisms, which remains mainly a manual task based on the engineer’s experience, intuition, and ingenuity. There, optimization techniques are only...

... the equations of motion of a multibody system along with the position kinematic constraints. The second batch of three algorithms draws on the HHT and BDF integration formulas and considers, in addition to the equations of motion, both the position and velocity kinematic constraint equations. Numerical...

... of a chain CVT. During the derivation of the equations of motion, special attention is turned on the exact description of the joint kinematics. An interesting method to speed up the numerical simulation of the chain drive is introduced, which takes into account the special structure of the mass matrix...

...Ahmed A. Shabana; Mahmoud Tobaa; Brian Marquis; Magdy El-Sibaie The sensitivity of the wheel/rail contact problem to the approximations made in some of the creepage expressions is examined in this investigation. It is known that railroad vehicle models that employ kinematic linearization can...
