Virtual prototyping of a spraying robotic system
The paper presents the virtual prototype of a robotic system for spray pyrolysis deposition (SPD). To design of the mechanical device model of the robotic system, the MBS environment ADAMS of MSC Software was used, while the MATLAB/Simulink of Mathworks was used for the dynamic analysis of the robotic system, according to the mechatronic concept. A control loop was chosen, composed by a multi-body mechanical model, connected to the dynamic model

The field of applying optocouplers, in the case when the user has access to the optical path of the light beam, is becoming larger and larger. Polaroid optocoupler LED–phototransistor is a device in which it is introduced a system of polaroid filters, on the path of the light beam that performs the optical coupling between the transmitter and receiver modules. By introducing this system of polaroid filters, one can modify the intensity of the output

The paper presents the modeling and simulation of the dual-axis tracking system of azimuthal type used for a photovoltaic (PV) platform. The study is approached in mechatronic concept, by integrating the mechanical device and the control system at the virtual prototype level, during the entire design process. The mechanical device model of the tracking mechanism is developed as multi-body system by using the MBS environment ADAMS, while the DFC EASY5

The chapter presents researches in the field of increasing the efficiency of the solar energy conversion in electric energy, using tracking systems that change the position of the photovoltaic (PV) panel in order to maximize the solar radiation degree of use. From efficiency and safety point of view, we have selected a dual-axis equatorial tracking system, with two degrees of freedom. The both motions (daily and seasonal) are driven by rotary actuators,

The paper presents a method to improve the efficiency of a photovoltaic (PV) string by employing a mono-axis tracking mechanism. The tracking system was optimized so that it has minimum energy consumption during tracking. The PV string simultaneously changes the daily position using a linear actuator which transmits the motion to all modules by a rack-pinion gear mechanism. The system is designed in virtual prototyping concept with the following

This article presents the virtual prototype of the tracking system used for improving the energetic efficiency of a photovoltaic panel. From the point of view of the efficiency and safety, a polar dual-axis system has been designed. Both motions (daily and seasonal) are driven by rotary actuators, which are coupled with worm gears for blocking the system in the stationary positions. The tracking system is approached in mechatronic concept, by integrating
