The influence of initial parameters of pneumatic accumulator on the dynamic characteristics of the actuator during braking back pressure

A pneumatic drive with back pressure braking is considered. The braking energy is recovered to the pneumatic accumulator. A schematic diagram of a regenerative pneumatic drive is given. The question of the influence of the initial parameters of the pneumatic accumulator on the dynamic characteristics of the pneumatic actuator is considered. The following initial parameters were set in the pneumatic accumulator: volume; pressure. The following were evaluated in a pneumatic drive: pressure in cavities before and after braking; output link speed. The energy consumption and speed of the pneumatic drive were determined critically. Graphic dependencies of the dynamic processes of the pneumatic drive are presented. The relationship of the initial parameters of the pneumatic accumulator with the criteria of energy consumption and speed is established.
