摘要： A method for optimizing the construction of a car body through simulations of deformations of one or more selected car body elements of the car body, the method comprising the steps: selecting the one or more car body elements of the car body for which the deformations should be determined, calculating a first set of deformation values of the selected car body elements through simulating a fully trimmed model of a first car body construction in a complete dynamic load simulation model during a specified time period; determining one or more forces that need to be applied in a reduced model of the first car body construction in an equivalent static load simulation model in order to achieve a second set of deformation values of the selected car body elements for the reduced model of the first car body construction, so that the second set of deformation values of the selected car body elements are corresponding to the first set of deformation values for the same selected car body elements; applying in an equivalent static load optimization simulation step, the one or more determined forces to a reduced model of a similar alternative second car body construction in the equivalent static load simulation model in order to achieve a third set of deformation values of the selected car body elements for the reduced model of the second car body construction; and determining if the third set of deformation values are within a predetermined desired deformation value range.
