Rotation-Rotation Mechanism moving with Respect to a Plane

Autor: Roxana Alexandra PETRE, Ion STROE, Andrei CRAIFALEANU

Publikováno v: INCAS Bulletin, Vol 11, Iss 4, Pp 123-131 (2019)

The relative motion of a robotic arm formed by homogeneous bars of different lengths and masses, hinged to each other is investigated. The first bar of the mechanism is articulated on a platform, considered for three cases: placed on the surface of t

Horizontal Flight Dynamics Simulations using a Simplified Airplane Model and Considering Wind Perturbation

Autor: Dan N. DUMITRIU, Andrei CRAIFALEANU, Ion STROE

Publikováno v: INCAS Bulletin, Vol 10, Iss 4, Pp 61-69 (2018)

An in-house method of Newton-Euler inverse dynamics guidance based on a simplified airplane model in horizontal flight was proposed in a previous paper presented at NMAS 2018 workshop [1]. The goal was to guide the airplane between two locations situ

Influence of drag force upon the shortest time trajectory of an aircraft

Autor: Andrei CRAIFALEANU, Roxana Alexandra PETRE

Publikováno v: INCAS Bulletin, Vol 7, Iss 2, Pp 63-70 (2015)

The shortest time trajectory of an aircraft between two given locations is determined using a simple mathematical model. By taking into account the drag force (viscous friction force with the air), a problem of variational calculus is obtained which

ANIMATED COMPUTER GRAPHICS FOR THE STUDY OF MECHANICAL VIBRATIONS

Autor: Andrei Craifaleanu, Catalin George Ion

Publikováno v: Journal of Industrial Design and Engineering Graphics, Vol 1, Iss 1 (2006)

The paper presents a computer code developed by the authors for the study of the small oscillations of a system of two pendulums, coupled one to each other, as well as to the fixed element, with linear springs and with linear viscous dampers. The cod
