Abstract
In this paper Visual Nastran software for the multibody simulation is used with the purpose of determining the solicitations in the vehicle body executing some characteristic manoeuvres on the road. The interaction between the tyre and the ground is determined using a linear analytical model that, with regard to Pacejka formulas, is more simple and able to give suitable results for a large field of variability. At the purpose a control program, written in Visual Basic, is elaborated to communicate with Visual Nastran by the Technology OLE Automation, that is a fundamental characteristic of the programming at objects for Visual Basic and for the programs operating in Microsoft Windows field. At the end the use of ANSYS Design Optimisation modulus permitted the structural optimisation of the steering plate, reducing considerably its weight with regard to original one.
