Ansys Motion
Multibody Dynamics Simulation
Robust Multibody Dynamic System Design with Ansys Motion
Ansys Motion is a completely integrated simulation environment for both component and system modelling.
It provides fast and accurate analysis for both rigid and flexible bodies, simultaneously, all from a single solver. System motion performance, stress-safety analysis, heat transfer, vibration and fatigue are integral.
Ansys Motion is the most robust and advanced simulation solution for multibody dynamic system design.
Ansys Motion Toolkits
Ansys Motion Car
Vehicle systems with many parts and interactions can be easily and conveniently modelled using the Car Toolkit. With this toolkit, it is possible to model various templates and subsystems used for vehicle ride and handling analyses, such as the suspension system, steering system and brakes. The Car Toolkit also contains libraries for tires.
Application areas:
- Characterisation of the suspension and steering system of a vehicle.
- Identification of vehicle ride and handling characteristics and feedback to the steering wheel.
- Analysis of the complete vehicle or individual subsystems.
Ansys Motion Drivetrain
Drivetrain is a toolkit that constructs power transmission devices including gears, bearings, shafts and housings. In particular, by calculating the gear excitation force under fluctuating speed/load conditions, vibration characteristics can be analysed accurately under the same conditions as the actual driving conditions. Drivetrain allows you to configure the gear pair model by entering the specifications required for the gear design and analyse the transmission errors for each gear (backlash). It provides catalogues from major bearing manufacturers to improve your modelling experience and allows gear geometry to be created from parametric sketches.
Application areas:
- Whine and rattle analysis of electric car speed reducer.
- Whine and rattle analysis of transmission systems including epicyclic gear trains.
- Rattle analysis and noise analysis of steering systems.
- Transmission error analysis for gear design.
Ansys Motion Links
Many mechanical systems contain flexible power transmission features like chains, tracks and belts. Connections between the individual links and contact between the links and the sprockets, pulleys and rollers mean that many hundreds of thousands of elements need to be set up and have their contact defined. The Chain/Track Toolkit provides an automated method for quickly setting up these systems and post-processing them in an easy manner.
Application areas:
- Track system in all tracked vehicles such as excavators and armored vehicles.
- Chain systems within various machines.
- All kinds of pulley, belt systems.
- Material conveying systems.
- Timing belts of engines.
Ansys Motion EasyFlex
The EasyFlex toolkit provides an automated mesh-free solver capability within Ansys Motion. It can be used to calculate the stress and deformation of flexible parts without the need for any knowledge of mesh generation technology and techniques. This leaves the Ansys Motion user free to focus their time on solving the engineering problems at hand.
Application areas:
- Automated mesh-free modelling of flexible components within multibody systems.
Unparalleled Capabilities to Analyze Systems and Mechanisms
Ansys Motion uses four tightly integrated solving schemes: rigid body, flexible body, modal and meshfree EasyFlex. This gives you unparalleled capabilities to analyse systems and mechanisms in any combination you want. Large assemblies with many millions of degrees of freedom can be studied with the effects of flexibility and contact included. Standard connections and joints then allow these systems to be connected together and loaded.
In addition to the basic package, Ansys Motion offers additional toolkits so users working in areas with specific multibody dynamic needs can work faster and more efficiently.
