calculation of gas spring
7 Design calculation 7.1 Overview The design calculation for a gas spring generally involves: force, force ratio, stroke and extended length, piston rod diameter, cylinder inner diameter and wall thickness. The design calculation for the gas spring is based on an ambient temperature of 20°C ± 2°C, and the influenceRead More…
Gas Spring Design calculation principle
6 Gas Spring Design calculation principle At constant ambient temperature, the working process of the gas spring can be regarded as an isothermal process, which should follow the gas state formula of Boyle’s law; see formula (1) or formula (2): PV=C………………(1) Or P1V1=P2V2 ………………(2) where P is the pressure (the pressure insideRead More…
