Some Considerations of using Virtual Reality in the Training Process Specific to Disciplines of Applied Mechanics Starețu, Ionel In this paper, we first discuss issues regarding the training in mechanical design using CAD software to develop the geometric model of the components, the simulation possibilities of functioning in the case of the model developed, when it may become part of a virtual setting. We present, in the second part of the paper, in brief, the reasons for the introduction of virtual reality with immersion in the processes of theoretical and practical training in mechanical disciplines. There are some considerations on the methodological implications and we propose an extension of the model Wegener. We describe a pilot station which is in progress to test the use of virtual reality in the training activities concerned. We present the first achievements in this direction namely, proper populating of the virtual setting, interconnection of Cyber Glove gloves with the virtual setting and manipulating virtual parts for visual observation and simple assembly operations.

A Study on Stevens' Power Law Applied on the Human Perception of a Running Vehicle Transmitted Vibrations Picu, Ana This paper studies the way humans perceive vibrations induced by a running vehicle, starting from Stevens’ Power Law. The measurable physical magnitude was the acceleration transmitted to the hand-arm system. The measurements were made with MEASTRO 01dB. A new four components model was developed, based on the results of this experiment. The conceptual model presented included an increase in discomfort with vibration magnitude as well as an increase of discomfort with duration of exposure.

The Operational Space's Micro-Geometrical Analysis of the R I R II Kinematics Chain Naidin, Gigi In order to systematize the three monomobile coupling kinematic chains was essential to find criteria which eliminate those coupling which are inefficient, from the mobility point of view. It is embraced, as main criteria, the robot’s manageability, through the volume element analysis, removing, this way, the decreased mobility points from the working space.

The Utilization of 3X3 Matrixes in Setting Kinematics Chains Analysis for Robots Components Naidin, Gigi Within the kinematic study of a rigid solid, its motion is studied faceto- face by a reference system, fixing positions, speeds and accelerations of a reference system, solidarily connected to the rigid solid.
