This paper explores the use of compliant mechanisms or flexible beams in vehicle suspension systems. An example of a compliant suspension mechanism is the leaf spring suspension commonly found on trucks. New concepts are developed through rigid-body replacement synthesis and other methods with the objective of improving wheel control. The compliant A-arm is discussed and shown to be a promising concept for further research based on FEA results and other comparisons. The A-Arm concept performs well in controlling wheel deflections and has low stress values in response to control forces when compared to other compliant concepts considered and leaf spring configurations. The A-Arm uses less space than than the other compliant concepts considered and the potential cost of manufacture and assembly is potentially equal to current leaf spring congifurations.
