摘      要：The purpose of this paper is to present a novel topology optimization approach to control precisely the output loads under static loads and harmonic *** introduce the Artificial Bar Element(ABE)at the designated output positions,where the output loads are equivalently measured and constrained with the nodal displacements of *** model is then formulated considering the output load constraints as well as the minimization of strain energy and dynamic displacement responses respectively under the static and dynamic *** influences of the ABEs stiffness,different material usages of the design domain,widths of the output loads constraint intervals and variation ratios of output loads are discussed in *** proposed method is verified with several numerical examples with clear and reasonable load transfer paths.
