Abstract

This study presents a novel nonlinear multibody approach for the structural modeling of helicopter blades. Unlike the conventional approach of using beam elements to represent the rotor blade, the present analysis utilizes a plate element, which assumes a nonlinear strain measure and rotation, as well as transverse shear deformation. The principle of virtual work is used to derive the equations of motion. Kinematic joints are modeled by a set of constraint equations, which are invoked in the formulation through the coordinate partitioning method. The capability of the present analysis is demonstrated by considering the structural dynamics response of a composite helicopter blade with a trailing edge flap.
