Structure optimization techniques under static load conditions have been widely used in
automotive industry for lightweight and performance improvement of modern cars. However, these static
load conditions could not represent all the severe situations of automobile parts which subjected to complex
loads varying with time, especially for lower control arm of front suspension. In this study, dynamic
optimization of lower control arm was performed by combing traditional static load optimization
techniques and multi-body dynamics by Equivalent Static Load (ESL). And the best draw-bead distribution
of the stamped lower control arm was attained. Comparing the MBD analysis results of the new design
derived from dynamic optimization and original structure, results show that the strength and stiffness was
increased significantly while the mass was almost unchanged.
Key words: Double-wishbone suspension , dynamic optimization, equivalent static load, lower control arm, , ,
