The following are terms in Autodesk Inventor simulation and analysis.
- acceleration
-
A vector quantity defined as the rate at which an object changes its velocity.
- analysis
-
In Autodesk Inventor, any form of real-world physical valuation. Valuations usually involve real materials, mass, densities, inertia, forces, and reactions. Included are rigid body motion studies, material stress studies, and frequency response.
- bearing load
-
It is the compressive load at the interface
- body load
-
The load applied to the entire part. Single entities such as a face, edge, or vertex are not valid selections.
- CAD edit
-
An edit of the model, such as a geometry feature, which affects the model directly. Thus, any regular consumer of the model, such as a parent assembly or a drawing, will witness the edit.
- CAE
-
Computer Aided Engineering (& Analysis). In practice, this term equates to software that assists with engineering analysis.
- contact
-
Defines how components interact with one another during the simulation.
- design constraint
-
A simulation output value.
- FEA
-
Finite Element Analysis. Currently the most common method to conduct many types of stress, frequency, thermal, and shock analyses. The term finite elements refer to refining the geometry into a series of small simple shapes, collectively called a mesh
- fixed constraint
-
Fixed constraint prevents the face, edge, or vertex from moving or deforming.
- force
-
A uniformly distributed load, when applied to a face or edge. A point load when applied to a vertex.
- frictionless constraint
-
Frictionless constraint prevents the surface from moving or deforming in the normal direction relative to the surface. The surface is free to rotate, move, or deform in a tangential direction to the applied frictionless constraint.
- gravity
-
Applies gravitational acceleration effect in the selected direction.
- limit
-
A bounding value for a result.
- override material
-
Material which overrides the assigned material during simulation. Use to evaluate different materials for the design solution.
- mesh
-
The collection of finite elements used to split up the body into discrete elements. The value you define for mesh divides the body in multiple elements for analysis.
- moment
-
The moment is calculated by multiplying the force by the perpendicular distance to the location at which the moments are about.
- normal
-
The load applied is in the direction perpendicular to the selected face.
- pin constraint
-
Applies a rotational constraint on the selected combination of cylindrical faces.
- pressure
-
Pressure when applied on a face is the force measured per unit area.
- reaction forces
-
The added force generated by the lack of motion when a force is applied on a part.
- reaction moments
-
The reaction generated by a load which generates a moment load.
- remote force
-
Load applied without modeling the source. For example, an engine is statically supported by three brackets. To analyze the brackets, use a remote force to represent the weight and location of the engine.
- rotational velocity
-
Rotational velocity is a quantitative expression of the amount of rotation that a spinning object undergoes per unit time. It is a vector quantity, consisting of an angular speed component and either of two defined directions or senses.
- simulation
-
In the context of Autodesk Inventor, the term Simulation has grown to be an equivalent term to analysis. Note, the Dynamic Simulation environment strictly refers to rigid body motion studies.
- stress analysis
-
An analysis showing that the model is statically and dynamically stable and free from divergence on application of external loads and frequencies.
