Shape Table (SHP) Window

A Shape Table (SHP) file contains multiple shapes. Shapes can be displayed in animation directly from a Shape Table, on the structure model in a connected Structure window.

• A "shape" is defined as any data from two or more measurements made at different test points & directions on the machine, structure or acoustic surface.

• Common types of shapes are Operating Deflection Shapes (ODS's), mode shapes, acoustic shapes, and engineering data shapes.

• Each shape in a Shape Table has one or more shape components.

• Each shape component has a unique measurement number (M#).

A Shape Table (SHP) file is used in a variety of different ways;

1. Save it from a Data Block window during animation or curve fitting.

2. Save it from an SDM SDM is an acronym for Structural Dynamics Modification. SDM is an algorithm that uses the modes of an unmodified structure together with FEA Objects that model structural modifications, and calculates the modes of the modified structure. SDM is very fast and provides useful results even when a modal model has only a few modes in it., FEA FEA is an acronym for Finite Element Analysis. FEA involves creating an FEA model by adding FEA elements (called FEA Objects in ME'scope) to a structure model. The FEA model can be solved for its FEA modes, and also used for other analyses in ME'scope., or FEA Model Updating calculation.

3. Save it from a Forced Sinusoidal Response calculation in a Data Block or Shape Table window.

4. Import it from a third party disk file.

5. Create a new Shape Table, and Manually enter data into it.

Adding a Shape Table to a Project

There are several ways to add a Shape Table to a Project All work in ME'scope is done with data contained in a Project file. A Project file can contain one or more Structure, Data Block, Shape Table, Acquisition, Program, Report, or Added files. Only one Project file can be open at a time. All of the names of the data files in the currently open Project are displayed in the top (or left) pane of the Project Flyout panel.;

1. Execute File | Import | Shape Table, and import shapes from a third party data file.

2. Double click on a Shape Table (SHP) file in the (right or lower) pane of the Project Fly-out Panel.

3. Right click on a Shape Table (SHP) file in the (right or lower) pane of the Project Fly-out Panel, and select Open from the menu.

Creating a Shape Table

There are several ways to create a new Shape Table in a Project;

1. Execute File | New | Shape Table in the ME'scope window, and manually enter or paste data into its Shape and DOFs spreadsheets.

2. Execute Curve Fit | Shapes | Save Shapes to save mode shapes from FRF An FRF (Frequency Response Function) is a cross-channel frequency domain function that defines the dynamic properties of a structure between an excitation Force and the Response caused by that force. An FRF is defined as the ratio (Response DFT / Force DFT). The FRF is a special case of a Transfer Function, where the response is the numerator (Output) and the force is the denominator (Input).-based curve fitting in a Data Block.

3. Execute Tools | Save Shapes to save the ODS ODS is an acronym for Operating Deflection Shape. An ODS is the deformation of a structure at two or more locations and/or directions due to its own operational forces and/or other applied forces. A time domain ODS characterizes the structural deformation at a specific time. A frequency domain ODS characterizes the structural deformation at a specific frequency. An ODS is a summation of contributions of the mode shapes of all resonances being excited by the specific operating condition. at the cursor position in a Data Block or Acquisition window.

4. Press the Save Shape button in the Transform | MIMO | Sinusoidal ODS dialog box, opened from a Data Block.

5. Press the Save Shape button in the Tools | Sinusoidal ODS dialog box, opened from a Shape Table with mode shapes in it.
