Grashof mechanism
WebGrashof’s criteria for four-bar mechanism: If we distinguish the lengths in a 4-bar mechanism as follow: s: the length of the shortest link l: the length of the longest link p, q: the length of the other two links The following relationship (Grashof’s criteria) must … WebJan 1, 1985 · Grashof [l] classified four-bar mechanisms into three types which he named double-cranks, rocker- cranks and double rockers. He provided a set of rules to identify …
