This paper presents the sequential kinematic design of a suspension system based on Axiomatic Design (AD). AD is also used to compare the current design configurations of typical suspension systems and design modifications based on the AD is proposed. Functional requirements (FRs) are defined from three independent suspension geometries (toe, camber and wheelbase) and two independent steering geometries (kingpin offset and caster). In addition, the corresponding design parameters (DPs) are selected using suspension hardpoints. Since the number of DPs is generally more than that of FRs, the method of grouping the DPs is presented. From the design equations, the multilink suspension results in a decoupled design, which is considered a good design compared with the other two types (McPherson strut and double wishbone). However, although the McPherson strut suspension is a cross-coupled design, a decoupled design can be achieved by replacing the coupled DPs with new DPs. Suspension kinematic design has a specific order, because the design matrix is triangular. Design sequences can be classified into two groups: the cross-coupled case and the decoupled case. However, the sequences of the two groups have a common point: that is, the order of wheelbase is different, but the rest are identical. Although this paper has presented the kinematic design of a suspension system, this methodology can be applied to kinematic design of general mechanical systems.
