Electric-motion in Romania — Overview: Study on machining parameters of EV charging station mechanical components
This paper presents some relevant aspects of charging infrastructure for electric vehicles in Romania. It evidences the charging station and fast charging stations designed and installed by the first Romanian company dedicated 100% to e-mobility, E-Motion Electric. Also, a study on machining (milling) parameters of some mechanical components of electric vehicle (EV) charging station is done and, finally, the regression model for these parameters is determined. This model would be further used for machining process optimization.
Electric-Motion Infrastructure in Romania - Research on Machining Processes of Mechanical Components of e-Motion Charging Station
Aspects of electric vehicles specific infrastructure in Romania are evidenced by this paper. The focus is on charging station and fast charging stations designed and installed by the first Romanian company dedicated 100% to e-mobility, E-Motion Electric. Research on machining processes, milling and drilling, of the mechanical components of these stations is also presented. A system for measuring the values of machining forces, data acquisition and processing, as well as real time control scheme does also represent innovation in this paper. The regression models, determined by statistical data processing, should be applied in optimization of machining process.
The Hybrid Position and Force Control of Robots with Compliance Function by Open Architecture Systems
This paper shows a new method for the hybrid position-force control of robots with compliance function on six axis of freedom degrees in system multi-microprocessor in order to obtain high performances. For this purpose kinematics and kinetostatics analysis are performed, and the mathematic model of the inverted kinematics is determined for controlling the main trajectory of the robot. Related to this there is presented an Open Architecture system for the robot position control in Cartesian coordinates through real time processing of the Jacobean matrix obtained out of the forward kinematics using the Denevit-Hartenberg method and calculating the Jacobean inverted matrix for feedback. The obtained results prove a significant reduction of the execution time for the real time control of robot's position in Cartesian coordinates and increased flexibility.
