The article discusses a research study on an approach in designing cellular truss-beams based on natural frequencies. Design complexities were lessened before solving the physical problems based on Axiomatic Design and in other cases, the use of the topology optimization tool for natural frequencies, the finite element method (FEM) for straight trusses free vibration analysis and the continuum modeling. The natural frequency for full truss structure was evaluated through FEM with the beam elements clamped together and the link elements pin-jointed to one another. Conclusions indicated the conversion of the system matrix to a lower triangle leading to decreased complexity of design through proper and systematic assumptions.
