Interpolation multipoint constraints with selection criteria of degree of freedoms for flexible multibody dynamics

作者：

Highlights：

• A new method is presented to extend the DOFs selection in the interpolation MPCs.

• The derived formula for a matrix rank can allow a non-invertible constraint matrix.

• A stable FMBD model can be more freely constructed through the suggested method.
