  • Method and apparatus for design and optimization for simulation of motion of mechanical linkages
    Patent number: 5297057
    Abstract: A method and apparatus for performing kinematic analysis of linkages using generalized mechanisms selected from a catalog of mechanisms. From an initial selection of mechanisms, the one most closely matching a desired behavior is chosen and an optimization procedure is conducted. The method may be preceded by a qualitative kinematic analysis or the qualitative analysis may be used in lieu of a catalog selection. An improved optimization technique and a closed form kinematic analysis method is described.
    Type: Grant
    Filed: November 13, 1991
    Date of Patent: March 22, 1994
    Assignee: Schlumberger Technologies, Inc.
    Inventors: Glenn A. Kramer, Harry G. Barrow, Patrick R. Turner, Michael E. Bodner, Jeffrey G. Cooper
  • Closed-form kinematics
    Patent number: 5043929
    Abstract: A method and apparatus for performing kinematic analysis of linkages is disclosed. Generalized mechanisms are selected from a catalog of mechanisms. From an initial selection of mechanisms, the one most closely matching a desired behavior is chosen and an optimization procedure is conducted. The method may be preceded by a qualitative kinematic analysis or the qualitative analysis may be used in lieu of a catalog selection. An improved optimization technique is disclosed, along with a closed form kinematic analysis method.
