Computer-aided analysis of the mechanical quality of a metal coating of an injection molded vehicle component

摘要

A computer-aided method of analyzing a mechanical quality of a metal coating of a vehicle component which is an injection molded vehicle component made of plastic, e.g. An inside door handle, comprising the steps of: step a) providing a first computer model that models the vehicle component, the first computer model being determined by at least the shape of the vehicle component and at least one component thermal expansion coefficient of at least one material of the vehicle component; Step b) providing a second computer model that models the metal coating, wherein the second computer model is determined by at least one thickness of the metal coating and at least one coefficient of thermal expansion of at least one material of the metal coating; Step c) computer simulating one or more mechanical stresses and / or strains occurring due to a temperature change of the metal coating and / or the vehicle component using the first and second computer models, wherein the simulating is for one or more locations in the metal coating and / or the vehicle component takes place; Step d) includes step d1) determining a mechanical weak point as a function of the one or more mechanical stresses and / or strains at the one or more locations and / or including step d2) computer-aided visualization of the one or more mechanical stresses and / or strains A method for improving the shape of the vehicle component, comprising a method according to the invention for predicting a mechanical weak point. Method for improving the metal coating of the vehicle component, including a method according to the invention for predicting a mechanical weak point. Computer program, computer program code on a storage medium, metal-coated vehicle component and vehicle door.
