For the option: | Value Type | Do the following: |
|---|---|---|
Include Damping | Yes/No | Option to include damping. |
Plant State Name | Existing plant state name | Name of the Plant State already existing in the model to be used for Eigen analysis. |
Reference Marker | Existing marker | Reference marker for Eigen analysis. Based on the settings, the relative coordinates are created. Without RM all default linearization coordinates are global. Using RM all default coordinates are relative to the RM marker. The RM option is useful in linearizing helicopter blades, turbines and so on. If no RM option is used, the computed frequencies reflect a dependency on the rotation frequency, hiding the frequencies of interest. When the RM option is used, Adams Solver (C++) selects a subset x of the coordinates shown in the table above to perform the linearization. For more details see section Using the RM option. |
Compute Eigenvalues and Eigenvectors / compute Eigenvalues only | string | Specify if only eigenvalues are to be calculated or of both eigenvalues and eigenvectors should be calculated. |
Frequency Range /Mode Range | string | Specify if results should be output for only a subset of the system modes. Define the subset either as the set of modes which lie within a given frequency range (frequency range) or as a range of specific mode numbers (mode range). |
Energy Of Modes | Integer | Range i1[,i2] of mode energy distribution. If you do not specify the number of modes you want to compute, Adams Vibration automatically chooses a suitable number of modes based on the model size. This options shows only if F77 solver is selected. Range: i2 > i1 > 0 |
Coordinates Of Modes | Real/Integer | Range i1[,i2] of coordinates for modes/frequencies. Range: ■i2 > i1 > 0 when Mode Range is selected. ■r2 > r1 > 0.0 when Frequency Range is selected. |
Dissipative Energy | Real/Integer | Range i1[,i2] of dissipative energy distribution for modes/frequencies. Range: ■i2 > i1 > 0 when Mode Range is selected. ■r2 > r1 > 0.0 when Frequency Range is selected. |
Kinetic Energy | Real/Integer | Range i1[,i2] of kinetic energy distribution for modes/frequencies. Range: ■i2 > i1 > 0 when Mode Range is selected. ■r2 > r1 > 0.0 when Frequency Range is selected. |
Strain Energy | Real/Integer | Range i1[,i2] of strain energy distribution for modes/frequencies. Range: ■i2 > i1 > 0 when Mode Range is selected. ■r2 > r1 > 0.0 when Frequency Range is selected. |
Names | Yes/No | If selected, this will list the energy contribution results by Adams View object name instead of Adams Solver ID. This options shows only if C++ solver is selected. |
Table Precision | Integer | Specify the number of decimal places to be used in the energy table output. This options shows only if C++ solver is selected. |
