Crashworthiness Simulation of Lower Control Arm Impact Tests

摘要

Finite element models of cast aluminum and stamped steel lower control arms (LCAs) were created to simulate subsystem tests of LCA with bushings and brackets. Several modelling methods were used to simulate the dynamic responses of cast aluminum LCAs, and the advantages and disadvantages of each method are discussed. Factors that are essential for modelling stamped steel components found in previous studies including strain rate, forming, and welding effects are incorporated in the stamped steel LCA models. Difficulties in modelling LCAs subsystem, possible remedies, and further improvements are also discussed in this paper.
