1 A Tutorial of Pro/MECHANICA Structure (Release 2001) Objectives Enhancing the Lecture on An Introduction to Pro/MECHANICA Structure Familiarizing Pro/MECHANICA Structure Menus Learning the Process of FEA Using Pro/M Pro/M user interface, windows, menus, mouse buttons Formation of A FEA Model: 1. Specification of part material 2. Specification of constraints 3. Specification of load conditions Mesh Generation FEA Analysis and Result Analysis Post-processing and Plotting Result Interpretation. Introduction Pro/MECHANICA is a powerful linear finite element analysis (FEA) package developed for design engineers. This tutorial serves as an introduction to the three main functions provided by Pro/MECHANICA. These are: structural, thermal, and motion analysis; design parameter sensitivity analysis; and design optimization. Pro/MECHANICA can work either as an independently FEA package, or as an integrated part of Pro/Engineering. This tutorial will outline its use in conjunction with Pro/E. The example part used in this tutorial will the same "base" part that we have used in the previous Pro/Engineer tutorial, as shown in Figure B (a). Assuming this part is part of a fixture for a milling machine. The part is tightened to the table of the mill through the center step hole using a bolt through the T slot. A block is pushed in horizontally to hold the part with the left arm of the dent. The left dent arm is then going to bear the holding force. The task of FEA is to calculate the maximum stress, verify the structural integrity, identify the week area and design the part with a minimum volume (weight) while satisfying the strength and deformation requirements. The FEA of the part is carried through the following process, illustrated in Figure A and discussed in the following.

3 Preparation of the Model 1. Copy the BASE.PRT, as shown in Figure B (a), to a new file for finite element analysis. Start Pro2001. Choose File -> Open, select BASE.PRT, then File -> Save As, enter the new name as BASE_FEM.PRT. Choose File -> Erase, Current to clear the window, then File -> Open, select BASE_FEM.PRT. 2. Create a groove at the intersection of the two plane surfaces When the base part is used as a fixture, the sharp corner will produce high stress concentration. A groove is usually created to reduce stress concentration. Given the previous experience in Pro/Engineer, you can create the feature without referring to the following description. Choose FEAT -> Create, FEAT CLASS -> Solid, SOLID -> Cut, SOLID OPTS -> Extrude, Solid, Done, ATTRIBUTES -> One Side, Done. SETUP SKPLN -> Setup New, SETUP PLANE -> Plane, GET SELECT -> Pick, click DTM3, DIRECTION -> Okay, SKET VIEW -> Right, SETUP PLANE -> Plane, GET SELECT -> Pick, left click DTM1.
