MetaModel is a method to make table data of gearforce and use it for dynamic analysis. There are 6 variables (Rotational Angle, Penetration, Distance Error, Axial Offset, Twist, Tilt) with which we can define gear pair geometry. User can define data points for each variable and then consist of gear force table data for all data points of selected variables in binary file having gmm extension. From the geometry of the gear pair at a specific time, RecurDyn solver performs dynamic analysis by calculating the value of 6 variables and then obtaning gear force from the table data of *.gmm file using computed value of 6 variables. For information about 6 variables, click here.
