The present invention relates to a method for optimally designing a hub and a drum of a vehicle brake system using finite element analysis. More specifically, the present invention relates to a method for optimally designing a hub and a drum of a vehicle brake system using finite element analysis, wherein main components such as a drum, a hub, a tie rod, a spindle arm, and an I-beam constituting a structure of a vehicle axle are selected so as to enable a physical property value of each of the components to be applied, and a stress value applied to the drum and the hub is calculated by substituting a driving condition, a load condition, and a restraint condition generated during driving so as to calculate the highest stress and a position thereof.;COPYRIGHT KIPO 2018
