Unformatted text preview: he center of mass of an aluminum block due to the forces FX and FY shown. Figure 196.1 Counter-Balanced Loads on a Block Problem Sketch Material Properties E = 70 x 109 N/m2 ρ = 2712 kg/m3 Geometric Properties h=3m =2m d = 300 m Loading FX = -2000 N FY = 3000 N Analysis Assumptions and Modeling Notes The problem is solved in two different ways: • using 3-D solid elements (SOLID45) • using 3-D solid elements (SOLID185) ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–444 VM196 The block must be constrained such that no rigid body motions occur. In a 3-D structure, six DOF must be constrained to prevent free-body motion by translation or rotation. The inertia relief algorithm is used to calculate accelerations to counterbalance the applied loads resulting in net zero values for the sum of the reaction forces. Results Comparison Target ANSYS Ratio MX (N-m) -909000 -909000 1.000 MY (N-m) -606000 -606000 1.000 -5000 -5000 1.000 Rotational accelerationsx (rad/sec ) -0.12...
