Abstract:
1. A performance evaluation method of a vehicle member, comprising: an information acquiring process which acquires full vehicle information calculated by a full vehicle CAE model; a member selecting process which selects a vehicle member to be evaluated based on the full vehicle information that has been acquired; a CAE model design process which designs a partial structure CAE model consisting of the vehicle member that has been selected; a first calculation process which calculates a collision performance evaluation parameter based on the partial structure CAE model that has been designed; a first storing process which stores the value of the collision performance evaluation parameter that has been calculated in the first calculation process; a second calculation process which calculates the collision performance evaluation parameter based on the full vehicle CAE model; a second storing process which stores the value of the collision performance evaluation parameter that has been calculated in the second calculation process; a boundary condition adjusting process which adjusts a boundary condition of the partial structure CAE model so that a deviation between the collision performance evaluation parameter calculated in the first calculation process and the collision performance evaluation parameter calculated in the second calculation process is not more than a predetermined value; a third storing process which stores the boundary condition of the partial structure CAE model that has been obtained in the boundary condition adjusting process; a boundary condition determining process which determines a boundary condition of a partial structure collision test device based on the boundary condition of the partial structure CAE model stored in the third storing process; a fourth storing process which stores the boundary condition of the partial structure collision test device that has been determined in the boundary condition determining process; and a test process which conducts a collision test using a physical instance of the partial structure collision test device and a physical instance of the member, based on the boundary condition of the partial structure collision test device stored in the fourth storing process.
