INTERNAL REACTION FORCES IN DYNAMICS OF A PLANAR PARALLEL MANIPULATOR
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2014, Vol 59, Issue 3
Abstract
Three identical legs connecting to the moving platform of a planar parallel manipulator are located in the same vertical plane. Knowing the motion of the platform, we determine the positions, velocities and accelerations of the robot. Using an approach based on the principle of virtual work, compact matrix dynamics equations and graphs of simulation for the input torques of three actuators and internal joint reaction forces are obtained.

ON THE ACOUSTICS OF THE STICK-SLIP PHENOMENON
In this paper, the acoustics and friction of the stick-slip phenomenon is discussed. The interaction friction-vibration gives rise to oscillations within solids which frequently lead to radiation of sound to the surround...

PROBABILISTIC SEISMIC VULNERABILITY ANALYSIS OF REINFORCED CONCRETE COLUMNS
Estimating the response of reinforced concrete columns to a transitory action, represented by a ground motion, is an uncertain task. The randomness of the seismic event and that of the response should be accounted for. T...
