Martin, Kinematics and Dynamics of Machines, 2nd Edition, McGraw-Hill Book Co., Inc., New York, NY, 1982, pp. 55-56, fig. 3-22. Analysis Type(s): Static Analysis (ANTYPE = 0) Element Type(s): Revolute Joint Elements (COMBIN7) 3-D Elastic Beam Elements (BEAM4) Spring-Damper Elements (COMBIN14) Linear Actuator Elements (LINK11) Input Listing: vm195.dat Test Case Determine the maximum force (Fmax) of a toggle mechanism acting upon a resisting spring. Figure 195.1 Toggle Mechanism Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–442 VM195 Material Properties E = 1 x 109 N/m2 Geometric Properties t = 0.1 m Ks = 166.67 N/m Ka = 100/d N/m α = 36.87° Loading Fa = 100 N Analysis Assumptions and Modeling Notes A linear actuator is used to apply a force, Fa, and move the toggle mechanism. The actuator force is increased by 2% to ensure complete mechanism motion. The actuator mu...
