Muttulingam OctoberĢ ANSYS Rigid Body Dynamics & Simplorer Why RBD? 2ģ Agenda Intro to Rigid Body Dynamics (RBD) System level analysis using Simplorer RBD co simulation Advanced user control using command snippets 3Ĥ History & Motive 15 years ago, most of the simulations were done on single part models Automatic contact detection and easy contact modeling Assemblies are now a common phenomenon for analysts Contact detection on an engine assembly Contact is not always what you need Some abstraction could be more efficient Kinematics description better for some cases 4ĥ Contact Based Kinematics Example of contact misuse Frictionless: Ear to Base, Pin to Base Bonded: Ear to Pin Pin Base Ear Solution time: 160 seconds 5Ħ Joint Based Kinematics Joints are a very elegant solution to this problem Developed for Rigid Body Solver, now also available in ANSYS Mechanical Revolute Joint: Ear to Base, Pin to Base Fixed Joint: Ear to Pin Pin Base Ear Solution time: 40 seconds 6ħ Joint Types Spherical Revolute Cylindrical Planar Universal Translational Slot 7Ĩ Where can I use Joints? Joints are available for most analyses Static, Modal, Transient, Harmonic, Random Vibration. 1 ANSYS Rigid Body Dynamics & Simplorer Mayuran S.
