This paper uses lumped parameter dynamic equations to model the mass flow, piston dynamics, and control volume behavior inside a free-piston Stirling engine. A new model for a Stirling engine thermal regenerator that incorporates a dynamically changing temperature gradient is presented. The use of graphite as a regenerator matrix material is justified despite its limited background by comparing...

In this article simulation studies have been carried out on the dynamic performance of a hydrostatic transmission (HST) system using two motor summation drive. In this respect a closed loop HST system that consists of a variable displacement swashplate controlled axial piston pump and bent axis piston motors is considered. Bondgraph simulation technique is used to model the hydrostatic drive sy...

A conceptual design of Stirling engine suitable for onboard aircraft application is the motivation behind this study. The aim to evaluate suitability system be integrated in as part energy contributor by recycling waste thermal energy. parametric evaluation an established Wobble-Yoke Engine state space model was performed determine a pre-compensator that able produce highest power output given ...

This paper describes one method to attain a robust positioning control of pneumatic driving system comprising a pneumatic cylinder and PCM digital control valves. A pneumatic driving system has become one of interests in the industrial fields, however, the control characteristics are inevitably affected by the friction force and parameter changes of plant due to air compressibility. The control...

The gas force due to the combustion in the cylinder of an IC engine will cause the piston to move with primary motion and secondary motion. The primary motion of the piston from TDC to BDC is linear in nature. This motion is desired for translation of motion of engine components. Secondary motion is due to the transverse motion of the piston while piston moving from TDC to BDC and vice-versa. T...
