Semi-active shock absorber |
摘要 |
<p>The suspension damper includes a full piston (2) which slides in an oil-filled upright cylinder (14) between a compression chamber (4) and an expansion chamber (5). Each chamber is connected to a common oleopneumatic accumulator (11) by an electrically operated valve (9, 10) by-passed by a non-return valve (8, 7). The piston rod (3) is equipped with a force transducer (12) and a relative speed sensor (13). In the direct control loop (19) the inverse model (15) determines a theoretical electric current (ith) for the electrohydraulic valves from the measured relative speed and a force set-point (Fc). The error (epsilon F) is applied (17) in production of a correction (delta i) for this current. <IMAGE></p> |
