It is proposed to use design and force diagram synthesis at preliminary designing of parts instead of (or parallel to) design methods using prototypes and analogues. As exemplified by fork of interaxle differential lock it is shown, that using of topological optimization method often allows to develop parts of higher strength and stiffness, and simultaneously to reduce parts mass without change of material.design and force diagramtopological optimizationfinite elements methodstrengthstiffnessdifferential lockwheeled vehicleконструкционно-силовая схематопологическая оптимизацияметод конечных элементовпрочностьжесткостьблокировка дифференциалаколесная машина[Bendsoe M.P., Kikuchi N.
