Startup Torsional Vibration of Rotating Machine Driven by Synchronous Motor,ation of startup, nonlinearity of the system is strong in both the electric circuit and gear teeth meshing, the amplitude of transient vibration depends on the interaction of the electro-mechanical system and high frequency vibration is incurred due to backlash of the gears.

Eric Giraud-Héraud,Marie-Claude Picheryontinuous system with the constant velocity. It is shown, that in the case of two interaction points between the both subsystems there exists a countable set of the bounded instability regions where solutions have an oscillating nature.

The Trouper on the Flying Trapezets. In case of deformable elements constitutive equations have to be supplied. They may express simply linear-elastic behaviour, but by these constitutive equations also active elements in a mechanism can be modeled. A dynamic simulation of a hydraulically actuated servo mechanism with flexible links is presented.

,On Steady-State Motions of an Axisymmetric Rigid Body on a »String« Suspension, simple geometrical constraint). However later the string was found to be inadequate for rotating large-size bodies. So the existing design of the “string” suspension had been made as a set of rather heavy axisymmetric bodies (rods), coupled through Hooke’s joints. An interesting apparent paradox wa

Dynamics of Gyroscopic Systems for Indicating the Vertical on Ships,the investigation for the case when the system angular momentum is constant in inertial space and not zero. The equations of motions for a new class of unperturbable systems are derived and their motion is investigated. In particular it is shown that the systems studied have both Schuler’s period an
