Abstract

A method for optimizing the construction of a car body through determining deformations of one or more selected car body elements of the car body, the method comprising the steps: selecting the one ormore car body elements of the car body for which the deformations should be determined, obtaining a first set of deformation values of the selected car body elements from a fully trimmed model of a first car body construction, wherein the first set of deformation values are based on measured dynamic values or simulated dynamic data in a complete dynamic load simulation model during a specified time period; determining one or more forces to be applied to a reduced model of the first car body construction in an equivalent static load simulation model to achieve a second set of deformation values of the selected car body elements for the reduced model of the first car body construction, wherein 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 the equivalent static load simulation model, the one or more determined forces to a reduced model of a similar alternative second car body construction 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 deformation value range for meeting deformation demands of the second car body construction.

Description

technical field [0001] The present disclosure relates to a method for optimizing a vehicle body structure by determining deformations of one or more selected body elements of the vehicle body, wherein deformation values ​​of the selected body elements are calculated. Background technique [0002] During the construction and design of modern vehicles, mathematical models or computer models are used to simulate the body or body components to better understand the structural properties of the vehicle structure. There are many different computer simulation models available for different stages of the automotive design process. Real test vehicles may also be used, and many times both real vehicle test procedures and computer simulations of vehicle models are used during construction. When developing a new vehicle, a computer model of the vehicle is often used instead of a real vehicle model. Computer models reduce costs and development time. [0003] An important aspect in the...
