A regenerative circuit is an amplifier circuit that employs positive feedback (also known as regeneration or reaction). [ 1 ] [ 2 ] Some of the output of the amplifying device is applied back to its input to add to the input signal, increasing the amplification. [ 3 ]
A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.
A hydraulic circuit is a system comprising an interconnected set of discrete components that transport liquid. The purpose of this system may be to control where fluid flows (as in a network of tubes of coolant in a thermodynamic system) or to control fluid pressure (as in hydraulic amplifiers).
Regenerative braking has a similar energy equation to the equation for the mechanical flywheel. Regenerative braking is a two-step process involving the motor/generator and the battery. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery.
The HLA system is called a parallel hydraulic hybrid. In parallel systems the original vehicle drive-line remains, allowing the vehicle to operate normally when the HLA system is disengaged. When the HLA is engaged, energy is captured during deceleration and released during acceleration, in contrast to series hydraulic hybrid systems which ...
This system was developed with front-wheel-drive cars' suspension design to maintain better control and stability during a system failure. A triangular split system was introduced on the Volvo 140 series from MY 1967, where the front disc brakes have a four-cylinder arrangement, and both circuits act on each front wheel and on one of the rear ...
A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.
A system developed at MIT uses hydraulic pistons to force fluid through a turbine coupled to a generator.The system is controlled by active electronics which optimize damping, which the inventors claim also results in a smoother ride compared to a conventional suspension.
