Dynamic Analysis of Open Loop Mechanisms. Part II.

Abstract

The report contains the analysis performed to derive the differential equations of motion for a general, open loop, spatial mechanism using the Lagrangian energy approach. The derivation uses closed loop (4x4) transformation matrix methods which are modified so they can be used in the analysis of open loop mechanisms. The report (and the analysis) is divided into two parts. In Part 1, the equations necessary to analyze the motion of a mechanism, which can have only force inputs, are derived. Part 2 adds to this analysis provisions for including motion inputs in a mechanism. This is done by transforming the motion input problem into a force input problem, analyzed in part 1, with an unknown dynamic force. The equations resulting from part 2 can be used to perform dynamic force analysis of mechanisms. (Modified author abstract)
