Dynamic Simulation

Dynamic Simulation

With Inventor, users can use Dynamic Simulation to predict how a product will work under real-world conditions, without having to build costly, time-consuming physical prototypes or hiring expensive analytical specialists. Simply add the driving loads, friction characteristics and dynamic components. Then, run the simulation to validate the design. Seamless integration with stress analysis validates component design with actual load information, rather than estimates.

ENHANCED Simulation

Simulate the operation of mechanisms and motorised assemblies to make sure your designs will work, whilst reducing physical prototyping costs. Compute the dynamic operating conditions of the design throughout its full operating cycle and accurately size motors and actuators to sustain actual operating loads. Provide a complete analysis of the positions, velocities, accelerations and loads encountered by each component of the mechanism.

Microsoft Excel Output

Export XY plot data to Microsoft® Excel® worksheets, to analyse simulations and incorporate results in presentations and reports.

ENHANCED Output to FEA

Transfer reaction forces from discrete time steps to Autodesk Inventor Stress Analysis or ANSYS® Workbench to predict stress and deflection with accurate peak loads. Size components, such as pins and linkages, to minimise weight and material costs.

ENHANCED Constraint Translation

Quickly and easily set up dynamic simulations to represent the operating conditions of the design. The constraint reduction engine analyses assembly constraints to identify the relevant rigid bodies and generate the correct motion joints for simulation. Apply standard geometric constraints using the included library of motion joints. Then add springs and dampers to define the coefficient of friction that applies to each joint.

ENHANCED Load Definition

Apply different driving loads and torques as well as time-based force functions using the load profile editor. Use this tool to investigate the design's performance under a range of different load conditions.

ENHANCED Visualisation

Animated 3D visualization shows dynamic motion based on underlying physics models and the applied load conditions. As a result, users gain a better understanding of the behaviour and performance of the design.

ENHANCED Point Trace

Determine accurate component position for sufficient clearance between mechanisms and fixed structures. Select any point in the model and use the Trace option to display the selected point's location at each step in the simulation. Save simulation output, including path trace and assembly position, for use in part and assembly design.

Graphing (Dynamic Simulation)

Use the comprehensive graphing capability to quickly investigate how the dynamic characteristics of the design vary through the machine's operating cycle. Plot physical parameters-such as position, force and acceleration-versus time. Compare different properties at each point in the simulation cycle using multiple plots on the same graph.
