The method was used in the preliminary design Received in revised form 22 September 2014 to size a compression spring implemented in a linear vehicle suspension system. Compared to Accepted 26 September 2014 conventional design methods, our design method avoids the passing through two stages of sizing Available online 8 November 2014 (static and dynamic). Using the numeric CSP approach, static and dynamic requirements can be coupled in the same step of sizing. It also avoids the falling on the loop “design–simulate–back Keywords: to the initial step in case of failure”, as the design parameter values of the compression spring gen- I
