This paper is based on designing a modified rotor for a drivetrain in a Type-III wind turbine system for maximum power generation to work effectively under low and high wind speed and its variation. In this paper three drive trains are designed for the gearbox to provide regulated torque and thrust force. For time to time variation in wind speed the voltage sag and during over speed condition voltage swell problem can be solved by using this modified design. The pitch control, gear box and yaw of the wind turbine basically focused for modification. Mainly the gear box for the rotor causes sluggish motion of the rotor during low wind speed. This paper explained the design of modified rotor control for the gear box in DFIG based (Type-III) wind turbine. Also in this paper how the modified rotor system can be helpful for reactive power control highlighted with comparison with existing models. For designing MATLAB Simulink platform is taken and validated using CFD mechanical design analysis. Using these types of modified drive trains maximum power for the wind turbines is enhanced by 40–60% of its reference value.

The paper presents optimization of the drive system in terms of adapting it to the characteristics of another engine. Powertrain parameters in a vehicle with an internal combustion engine were selected based on the following criteria: fuel consumption, engine dynamics, and emission standards for harmful substances. A light-duty passenger vehicle with gross vehicle weight rating (GVWR) of 3.5 tons was modified by replacing a spark-ignition engine with a diesel engine. The gear ratio in the powertrain had to be modified accordingly to optimize the engine’s performance, enhance engine dynamics, minimize fuel consumption and toxic emissions. The optimization of selected parameters of the vehicle driveline was performed based on the requirements of the standard NEDC and WLTC cycles.

The change in the shape of biconvex-concave teeth profile as a result of bevel gears teeth wear was established experimentally. The wear influence on the tooth curvature radiuses, the rolling and sliding velocities of mating profiles and the teeth contact stresses was examined. The characteristics, which affected the wear process, were determined. A three-dimensional picture of the teeth wear distribution was presented.

This paper presents an analytical and computer aided procedure for the multicriteria design optimisation of planetary gear trains. Geometric and operating constraints for internal and external gears and whole planetary gear trains are defined. For the defined multicriteria optimisation model of the planetary gear train, a computer program based on an interactive dialogue is developed. The results of the program are presented on an appropriate tables with Pareto-optimal solutions. A graphical illustration of the above problem is presented in terms of objective functions.
