Thermally boosted concept for improved energy storage capacity of a hydro-pneumatic accumulator... This is especially true for hydraulic hybrid vehicles which use a hydro-pneumatic accumulator as the energy storage device....
Gravitational potential energy recovery and recycle of rotary drilling rig... In order to improve the economic benefits of tunneling to rotary drilling rig,in this paper,the rotary drilling rig main winch hydraulic system was improved,by increasing an hydro pneumatic accumulator storage and releasing gravitational potential energy of kelly bar,as well as increasing reversing motor and the main winch motor to form a hydraulic transformer.So...
Modeling, simulation and design optimization of a series hydraulic hybrid vehicle... Series hydraulic hybrid system is a mechatronics system with two source of power (that includes prime mover and hydro-pneumatic accumulator) which drives the vehicle....
Modeling and simulation of a hydro-pneumatic accumulator system for hybrid air development... This paper laid the emphasis on the multi-domain modeling and simulation of a hydro-pneumatic accumulator system, and then continues to study its dynamic behavior of the compressed air and output performance of the pump/motor with simulation....
