On the basis of analyzing the question about matching of rigidity and equip\|intensity design of the twin torsion bar, the method of designing the torsion bars is formed. By analyzing the diagram of control bars of double wishbone suspension with twin torsion bar, the geometry characteristic of control bars and calculating method of the suspension's rigidity are gotten. The question about matching of rigidity is analyzed to ensure suspension's load and rigidity, and the question about equip\|intensity design is analyzed to ensure the equal intensity of the torsion bars. The example proves that the method of matching of rigidity and equip\|intensity design of the twin torsion bar is practicable.
