Type Synthesis of Spatial Mechanisms

抄録

In this paper, a type synthesis system for production of prototype spatial multilink mechanisms constructed with multiple closed loops is investigated. This study was carried out to obtain optimum arrangements of links in the mechanisms. Consideration was given to the restrictive conditions of the mechanisms to be produced; i.e., closed loops in the mechanisms were constructed with some open chains, which are called open-chain elements in the present paper. Moreover, optimum conditions to satisfy the types of spatial mechanisms required were formulated using characteristics of the above-mentioned open chains, and a type synthesis system which determines the types of spatial multilink mechanisms was obtained. Applying the system, we synthesized a type of spatial six-link mechanism as a practical example.
