Abstract: A method for optimizing construction of a car body includes selecting body element(s) and obtaining first deformation values therefor from a fully-trimmed model of a first car body construction based on measured dynamic values or simulated dynamic data in a dynamic load simulation during a time period; determining force(s) to be applied to a reduced model of the first car body construction in an equivalent static load simulation model to achieve second deformation values of the element(s) for the reduced model, the second values correspond to the first values for the same element(s); applying in the equivalent static load simulation model, the determined force(s) to a reduced model of an alternative car body construction to achieve third deformation values of the element(s) for the reduced model of the second car body construction; determining if the third values are within a predetermined deformation range for the second car body construction.
