CompLUTMCK¶

CompLUTMCK can be used to include components into the simulation, whose rpm-dependent M-, C-, and K-matrices (e.g. bearings) are known from Look-Up-Tables.

class +AMrotorSIM.+Components.@CompLUTMCK.CompLUTMCK(arg)¶

Bases: AMrotorSIM.Components.Component

CompLUTMCK class for variable (e.g variable over rpm) mass, damping, stiffness matrices from Look-Up-Table

CompLUTMCK(arg)¶

Constructor

Parameters: arg (struct) – cnfg_component substruct of cnfg-struct
Returns: CompLUTMCK object

+AMrotorSIM.+Components.@CompLUTMCK.create_ele_loc_matrix(self)¶

+AMrotorSIM.+Components.@CompLUTMCK.LookUpTable(self, rpmTable, inputCell, rpmCurrent)¶

Includes parameters (M, C, K) from LUT into CompLUTMCK object with interpolation

Parameters

rpmTable (vector) – Rpm values of LUT
inputCell (cell) – Corresponding values of interest (M, C or K)
rpmCurrent (double) – Rotation speed of interest (for interpolation)

Returns

Desired ouput matrix (M, C or K)

+AMrotorSIM.+Components.@CompLUTMCK.print(obj)¶

Displays the object name in the Command Window

Parameters: obj (object) – Objects of type Component
Returns: Notification of object name

+AMrotorSIM.+Components.@CompLUTMCK.warn_for_non_integrable_component(self)¶

Displays a warning message and asks for further action

Returns: Warning message
