CALCULUS OF THE TORSOR OF INERTIA FORCES FOR A RIGID SOLID BODY IN GENERAL MOTION
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2018, Vol 63, Issue 2
Abstract
The calculus of the torsor of the inertia forces for a rigid solid body in general motion is a very important matter for its next dynamic study. In other words if we aim to perform the dynamic survey of a rigid solid body we must determine first the torque of its inertia forces about an arbitrary point. For this reason the present paper deals with the calculus of its elements: the resultant force vector and the resultant moment vector.

VALIDATION OF NEW RIGID BODY DYNAMICS FORMULATION USING ROTATION MATRICES ELEMENTS AS DEPENDENT PARAMETERS − DOUBLE PENDULUM CASE STUDY
The method of using the rotation matrix elements as dependent parameters for the 3D rotation of a rigid body is currently very rarely used in multibody dynamics. Nevertheless, this redundant parameterization of 3D rotati...

CALCULUS OF JOINT FORCES IN DYNAMICS OF A 3-PRR PLANAR PARALLEL ROBOT
Recursive matrix relations for the joint forces in dynamics of a planar 3-PRR parallel robot are established in this paper. Knowing the kinematics of the platform, we develop the inverse dynamic problem, using an approac...
UNIFIED SLENDERNESS LIMITS FOR STRUCTURAL STEEL CIRCULAR HOLLOW SECTIONS
Circular hollow sections (CHS) are widely used in a range of structural engineering applications. The sections may be hot-finished or cold-formed from a variety of metallic materials with a range of yield strengths. The...
EFFECT OF LOW AND EXTREME-LOW TEMPERATURE ON MECHANICAL PROPERTIES OF 3D-PRINTED POLYETHYLENE TEREPHTHALATE GLYCOL
This paper investigates the mechanical behavior of 3D-printed Polyethylene Terephthalate Glycol (PETG) before and after exposure to low and extreme-low temperature. Before printing, melt shear viscosity of the PETG was i...
