Design workflow for load-bearing parts by the example of interaxle differential lock fork of a multiaxial wheeled vehicle

Technique of load-bearing parts design based on topological optimization method for solution of synthesis of design and force diagram of parts is considered. 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.
