Hmotový systém s vůlí a dvěma pružinami se nejdříve vychýlí. Determine the natural oscillations of the system - deflection, velocity, and acceleration time course.
Tento verifikační příklad vychází z verifikačního příkladu 0122. A single-mass system without damping is subjected to an axial loading force. An ideal elastic-plastic material with characteristics is assumed. Determine the time course of the end-point deflection, velocity, and acceleration.
A double-mass oscillator consists of two linear springs and masses, which are concentrated at the nodes. Vlastní tíha pružin je zanedbána. Determine the natural frequencies of the system.
Dvojhmotový systém se skládá ze dvou hřídelů a dvou hmot reprezentovaných příslušnými momenty setrvačnosti soustředěnými v dané vzdálenosti jako uzlové hmoty. The left shaft is fixed, and the right mass is free. Neglecting the self‑weight of the shafts, determine the torsional natural frequencies of the system.
A cantilever beam with an I-beam cross-section of length L is defined. The beam has five mass points with masses m acting in the X-direction. Vlastní tíhu zanedbáme. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
