Engineering Design of a Test Device

Experimental and computational comparative study of the specimens loaded by bending and torsion

“…For bending we can determinate that the stress and strain values have a dominant values; it means stress  xx and strain ε xx . The same phenomenon has been observed for the torsion at the stress and strain values; it means stress  xy and strain ε xy [9,10]. Obtained stress values allow determine the plastic deformation amplitude for each load step (turning step by step the gear -37 steps = 1 turn).…”

Analysis of the influence of the pipe’s wall thickness on the corrugation of the surface during inductive bending of pipes

“…Their contact with the tube as well as heat transfer in the respective contact are defined. The bodies which have coolant temperature are also formed at the point of the spray, and contact with the surface of the tube is defined [5].…”

Modelling and Simulation of Machine Tool Prototype with 6DOF Parallel Mechanism in Matlab / Simulink

“…Parallel mechanisms actuated in parallel by several serial kinematic chains can offer higher accuracy and stiffness, very high motion speed, and heavier payloads than their serial opponents [1][2][3][4][5]. Nowadays, the conventional parallel mechanism with six degrees of freedom (DOFs) of three translations and three rotations (structure 3T3R), also known as the Stewart platform, can be found in wide variety of applications involving motion simulators [6,7], parallel machine tools [8][9], force-torque sensors [10][11][12], heavy-duty free forming production machine [13], testing stands, antennas, micro-positioning units [14][15], calibration devices [16], etc.…”
