Abstract

The elapsing time to launch a new shock absorber to the market is usually conditioned by the adjustment or tuning of the internal valves to obtain the desired velocity-force curve, which is a tedious work that requires a deep knowledge of the particular characteristics of the shock absorber to be tuned. The goal of the present work is to make this procedure in a completely automated way. For that purpose, a numerical model implemented in a software tool, HIDROLIP, is presented.

Two underlying numerical analyzers form the basis of this software:

- The evaluation module. In few seconds gives an accurate estimation of the characteristic shock absorber curve. It can be used as an standalone tool for manual optimization.

- The optimization module. By means of repetitive calls to the evaluator, the best configuration of the internal valves (piston and compression valve) is calculated. The program also gives the chance of choosing between other quasi-optimal configurations, which could be preferable due to simplicity reasons.
