Simulation of contact spring

(for EATON Gdańsk - now DELPHI AUTOMOTIVE SYSTEMS)

Simulation of the manufacturing process of a spring in a car light switch was carried out with the use of ANSYS FEM code. Computation took into account elasticity effects. The deflection of the switch spring during manufacturing process has an influence on the force exerted by the spring in the switch, as well as tolerances of the spring. Influence of manufacturing tolerances and material properties variation on the force exerted by the spring was investigated. Results show, that variation of material properties has lower influence on the spring constant than working tolerances. As a conclusion a spring deflection in manufacturing process and manufacturing tolerances required to obtain a desired spring characteristic were specified.
