40.2. Multi Mass Spring Type B

MMS Type B is a method for modeling Multi-Mass-Spring and this method is supplied by BMW AG. MMS Type B is composed of geometric spring shape and multi-mass bodies, which are connected with translational joints and axial force. The axial force represents nonlinear spring characteristic using interpolation of stiffness/damping splines
