Web01. jan 2024. · Nowadays, passive oleo-pneumatic shock absorbers are widely used in aircraft [3]. The inerter is a recently introduced mechanical element, in which the properties are that the applied force is proportional to the relative acceleration between its terminals [5]. With the usage of inerter, a complete analogy between mechanical and electrical ... Webenergy using an oleo-pneumatic shock absorber which essentially consists of an oil damper and a gas spring. An oil flow through an orifice builds up a high back pressure which can react against the moving piston and hence provide high resistance to motion. This creates the damper. The damper is ineffective at low speed since it is the rate of
