ENGINEERING AND KNOW-HOW

KNOW-HOW

Like all springs, spring washers are calculated by applying classical theories of material strength. Calculations are used to determine the value of forces and stresses as per deformations.

Provided that the starting hypotheses are properly chosen, these calculations are accurate and correspond closely with experimentally controlled measurements.

Borrelly's engineers bring all their know-how to bear by studying problematic issues on a case-by-case basis, and propose customized solutions based on studies of linear or non-linear static behaviours with large finite-element displacements.
