- W75276767 abstract "Explicit finite element analysis (FEA) simulations are widely used in the productdevelopment of cars to evaluate their crash safety. Thus helping save substantialamount of resources required if only physical testing was to be used. At present thereare several areas where simple modelling techniques are still used, primarily becauseof limited knowledge about the detailed behaviour of the system in a crash.One such area is engine suspension components, e.g. engine and gearbox mounts. Theobjective of this thesis work is to develop new and improved finite element (FE)models for engine suspension mounts to be used in full vehicle crash simulations.These components play an important role in both high-speed crashes wherein failureoccurs in the engine mount and in low speed crash where the dynamic properties ofthe engine mount are of interest in capturing the motion of the components in theengine bay. The new model should replace the usage of multi dimensional springelements currently used in the existing models at Volvo Car Corporation (VCC).The methodology used to achieve the objective was to perform component and subassembly level tests in Fall Rig and correlate the test results by conductingsimulations in the explicit solver LS-DYNA. Material models derived from thefracture curves are used to visualize the crack propagation in the aluminium casting.A detailed FE model for engine mount has been developed from the observationsmade during correlation of Fall Rig tests. The new model was incorporated in the fullvehicle crash simulations. The new model showed good agreement with the existingmodel for the engine mount and observations from actual crash tests." @default.
