The requirements for Ansys Motion

Setting Up Multibody Dynamics Simulations

To begin, ensure your computer meets the software requirements for Ansys Motion. Open the application and navigate to the simulation interface for structural analysis.

Start by modeling components in the pre-processor. Treat components as separate part and mesh files for increased efficiency and data reuse. For complex 3D CAD models, utilize EasyFlex to streamline stress and strain calculations without traditional meshing challenges.

Create your multibody dynamics (MBD) model by defining your system. For rigid bodies, use MBD Pro from your base package. This tool employs parametric generalized coordinate systems to establish motion equations, linking rigid bodies through joints and constraints. Implement bushings, contacts, and user-defined functions as needed for your specific setup.

For flexible bodies, select the modal flexible body option for components without dynamic contact. This choice uses efficient computation via reduced modal coordinates. The seamless switch feature allows alternating between modal and nodal flexible bodies as required.

The drivetrain toolkit is beneficial for gear systems, offering Tooth Contact Pressure (TCP) and Deformation (TCD) calculations. These additions enhance gear performance insights, allowing examination of factors like stiffness and tolerance.

The solver combines MBD and finite element (FE) analysis, with specific connecting elements for various body interactions. Implicit integration methods provide smooth solutions without numerical noise.

For linked mechanisms, utilize the Links toolkit for chains and belts. Defined path and segment bodies transform into chain assemblies, with automatic track assembly selection. Proprietary geometries facilitate accurate modeling of real shapes.

MATLAB users can integrate mechanical models with MATLAB control models using the MATLAB/Simulink interface. For FMI users, co-simulation with other tools is possible, with Ansys Motion acting as a slave simulator.

Utilize guide messages for troubleshooting and Python support for defining motion and force magnitudes, automating processes, and improving efficiency.

Integration with Ansys Ecosystem

Connecting Ansys Motion to the wider Ansys ecosystem expands analytical capabilities. Ansys Mechanical enhances multibody dynamics simulations with insights into structural strengths and response characteristics. The familiar interface facilitates a smooth transition between mechanical and multibody dynamics analyses.

Ansys Fluent introduces comprehensive fluid dynamics to simulations. This integration allows analysis of fluid responses, interactions, and resulting forces, valuable for refining designs in scenarios like airfoil motion or marine systems in turbulent waters.

Incorporating both structural and fluid aspects in MBD simulations provides a complete analysis environment, accurately reflecting real-world dynamics. This integration explores how fluid dynamics and structural constraints affect system behaviors under various conditions.

The unified simulation environment improves workflow management by maintaining consistent models and data across platforms. Real-time feedback from Ansys Motion, combined with advanced plotting and visualization in Mechanical and Fluent, provides actionable insights for design decisions.

This integration optimizes tools rather than simply connecting them, resulting in a seamless analysis universe where simulations are interconnected parts of a well-mapped area, allowing designs to develop with precision and confidence.

Advanced Modeling and Solver Capabilities

Ansys Motion’s advanced modeling and solver capabilities enable precise and efficient large-scale simulations. The sophisticated solver technology manages complex kinematics and dynamics scenarios, efficiently handling simulations with millions of degrees of freedom. Utilizing shared memory parallel processing (SMP) and massive parallel processing (MPP) environments, simulations run quickly, meeting high-volume computational needs.

The software offers various flexible modeling options, allowing users to adapt simulations based on specific requirements. Switching between rigid and flexible body dynamics enables detailed adjustments based on the task, expanding simulation scope and improving result relevance.

Ansys Motion incorporates numerous constraints, joints, and connecting elements for advanced modeling. The parametric generalized coordinate system simulates dynamic interactions realistically, including flexibility and contact effects in large assemblies.

The software also simulates natural frequencies and modes of systems using eigenvalue and eigenvector solutions for finite element bodies. This analysis provides crucial insights into potential resonances that could affect design integrity, helping prevent structural failures and enhance system durability.

Solver mechanics support easy switching between modal and nodal flexible bodies, allowing smooth transitions between simulation detail levels. This feature balances computational costs and result accuracy, demonstrating Ansys Motion’s commitment to precision without sacrificing efficiency.

In multibody dynamics simulations, precision and efficiency are crucial. Ansys Motion offers comprehensive technologies that allow engineers to handle rigid and flexible body dynamics accurately. By integrating with the broader Ansys ecosystem, it simplifies complex simulations and improves predictive accuracy, ensuring that designs are practical solutions ready for real-world use.
