摘要：The linea. sea. suspension is considered due to the low cost considera.ion therefore, the optima. linea. sea. suspension design method ca. be used for this purpose. In this pa.er, the design of a.pa.sive vehicle sea. suspension system wa. ha.dled in the fra.ework of linea. optimiza.ion. The va.ia.ce of the dyna.ic loa. resulting from the vibra.ing vehicle opera.ing a. a.consta.t speed wa. used a. the performa.ce mea.ure of a.suspension system. Using 4-DOF huma. body model developed by a.ba. et a.., with linea. sea. suspension a.d coupled with ha.f ca. model. a.genetic a.gorithm is a.plied to solve the linea. optimiza.ion problem. The optima. design pa.a.eters of the sea. suspension systems obta.ned a.e kse = 3 012.5 N/m a.d cse = 1 210.4 N.s/m, respectively.
