MEC626 (F11) Lab Project # 1: ANSYS for Plane and Space Truss Analysis Prepared by Dr. J. Cao 1 RYERSON UNIVERSITY Department of Mechanical and Industrial Engineering MEC626: Applied Finite Elements Lab Project #1: ANSYS for Plane and Space Truss Analysis Instructor: Dr. J. Cao Note: The lab report for this project should be submitted on time. Late report will receive no marks. For the following truss structures, use ANSYS to determine the deflection of each joint, the stress in each element, and the reaction forces. Problem 1 : 2-D Balcony Truss For the balcony truss shown below, all elements are made from Douglas-fir wood with a modulus of elasticity of 2 6 / 10 90 . 1 in lb E and a cross-sectional area of 2 8 in A , all supports are ball-and-socket joints. Solution (using ANSYS): I. We need to open the Ansys 11 application first. 1. Go to Start, type “MECHANICAL APDL (ANSYS)”, and hit Enter. Then, give the Simplified Version a Title. 1. In the Utility menu bar select File > Change Title : 2. To get the title to appear immediately, select Utility Menu > Plot > Replot

MEC626 (F11) Lab Project # 1: ANSYS for Plane and Space Truss Analysis Prepared by Dr. J. Cao 2 II. Now we can begin with the problem. 1. Enter Keypoints o From the 'ANSYS Main Menu' select: Preprocessor > Modeling > Create > Keypoints > In Active CS o To define the N0.1 keypoint which has the coordinates x = 0 and y = 0: Enter keypoint number 1 in the appropriate box, and enter the x,y coordinates: 0, 0 in their appropriate boxes Click 'Apply' to accept what you have typed. o Enter the remaining keypoints using the same method. o When entering the final data point, click on 'OK' to indicate that you are finished entering keypoints. Note: If you made a mistake in the location of a keypoint, go through: Preprocessor > Modeling > Delete > Keypoints. Select the keypoint and press “OK”. 1.1. Form Lines The keypoints must now be connected In the main menu select: Preprocessor > Modeling > Create > Lines > Lines > In Active Coord . o
