CP10: Theoretical Study of Small Vibrations of Two Rigid Bodies with Damping

Conference Papers

ABSTRACT: This theoretical article continues the study of the small three-dimensional vibrations of two rigid bodies. Here, they are connected not only with elastic but also with viscous damping elements. The main task of this study is also to show how is composed the system of differential equations and how is determined the damping matrix. The […]

CP09: Theoretical Study of Small Vibrations of Two Rigid Bodies without Damping

Conference Papers

ABSTRACT: The small three-dimensional vibrations of two rigid bodies connected with elastic elements are studied in this research. The main task in the paper is to show how the system of differential equations is formed, which describes these vibrations without considering the damping. For determining the stiffness matrix, the Finite Element Method (FEM) is used. The

CP07: Theorem for Change of the Rigid Body Generalized Impulse

Conference Papers

ABSTRACT: In this conference paper, a rigid body’s absolute general motion is studied. The rigid body is assumed as homogeneous and unsymmetrical. New additional kinetic characteristics are used. The most important of these are the following: the vector-real generalized velocity of the rigid body, the vector-generalized impulse of the rigid body, and the vector-real generalized force

A14: Theoretical Matrix Study of Rigid Body Relative Motion

Articles

ABSTRACT: The relative motion of an arbitrary asymmetrical rigid body in this article is studied. Three new additional kinematic characteristics are defined, namely, vectors-real absolute, transmissive, and relative generalized velocity. A new theorem for summation of the rigid body’s real generalized velocities, with these new additional kinematic characteristics, is formulated. Using the final differential equations

A10: Experimental Determination of Vibration Levels of Electric Compressor Aggregate

Articles

ABSTRACT: Vibrations resulting from powertrain work and auxiliary equipment reduce the comfort, reliability, and durability of the vehicles. The vibration levels transmitted to the passenger compartment and the emitted structural noise depend mainly on the efficiency of their vibration isolation with respect to the vehicle body. The work presents an experimental determination of the vibration
