In 2023, 18.3 GW of new wind energy conversion capacity was installed in Europe; most of them (79%) represent onshore capacities. Most of this energy production is achieved with horizontal axis wind turbines. For this type of turbine, the location of the transmission coupled with an electric generator or a hydraulic group, in the turbine platform, leads to a significant increase in the mass of the platform, and implicitly in the mass of the pillar that supports the turbine. In addition, turbine maintenance becomes...

The article presents the creation of an experimental model of a hybrid vehicle intended to work both in conventional environments, in which the use of a diesel engine is permitted, and in environments with pollution restrictions (noxious emissions), in which an electric motor powered by batteries is used. At the level of the experimental model, the chassis of the drive train was made and tested, and the results were compared with those obtained by simulation with AMESim. The equipment in the NRMM (non-road mobile ...

In Romania, there are great possibilities for conversion and use of renewable energies, especially wind and solar energy. In order to maximize solar energy conversion, both as thermal energy and electrical energy, there are used sun tracking systems for solar thermal or photovoltaic panels, implying various types of drive: electric, pneumatic or hydrostatic. Based on the experience of more than 50 years in the field of hydraulic and pneumatic drives owned by the Institute INOE 2000-IHP, there have been designed tr...
