ABSTRACT:
A vehicular frame assembly is manufactured by initially providing a vehicular frame assembly that is formed from a plurality of structural members, each having an inherent torsional rigidity. Then, a desired inherent torsional rigidity can be determined for at least one of the plurality of structural members. Lastly, the at least one of the plurality of structural members can be deformed to achieve the desired inherent torsional rigidity. Alternatively, the vehicular frame assembly can be manufactured by initially providing a plurality of structural members, each having an inherent torsional rigidity. A desired inherent torsional rigidity can be determined for at least one of the plurality of structural members, and the at least one of the plurality of structural members is deformed to achieve the desired inherent torsional rigidity. Lastly, the plurality of structural members can be assembled to form the vehicular frame assembly.
