“…Within this construct, the expected formation of band gaps effectively inhibits wave propagation [10][11][12]. Exploiting these band gap characteristics allows for the deliberate design of novel phenomena, including negative refraction [13], advanced filtering mechanisms [14], and directional waveguides [15], combining both Bragg scattering [16][17][18][19] and local resonance [20][21][22][23] mechanisms in wave controlling metamaterials.…”

Strength and band gap are the two basic physical features of the cubic metamaterial. How to design band gap characteristics with high strength of structure is the key for the further industrial application in vibration control of the cubic metamaterial. Here a cubic metamaterial is designed by optimal selection of crystal orientation angle to obtain wide band gaps with high strength. The prototype samples were fabricated using advanced additive manufacturing technology to tensile-pressure experiments and sine frequency sweep experiment, thereby demonstrating the validity of the obtained results. Results indicated that the normalized bandwidth of SC metamaterials is 0.47 and the ultimate strength is 25.99 MPa. The normalized bandwidth is increased by 3.1 times and 47 times higher than that of the metamaterials of FCC and BCC. Its ultimate strength is increased by 3.5 times and 6.7 times. The static simulation results revealed that the maximum mises stress values of SC, FCC, and BCC metamaterials were 1.71MPa, 10.49MPa, and 31.40MPa respectively. The attenuation amplitude of the elastic wave measured by experiment is 80dB, which is consistent with the simulation results. The bandwidths of cubic metamaterials exhibit a positive correlation with their strength. The variation in crystal orientation angles plays a crucial role in elucidating the underlying mechanism behind the positive correlation between the strength and the band gap. The further buckling analysis of SC metamaterial with high strength and wide bandgap characteristics reveals that the negative Poisson's ratio structure experiences a reduction in bandwidth and strength as buckling deformation intensifies.

“…Various topology optimization strategies have been used in phononic materials to maximize the band gap between two adjacent bands in the phononic band diagram, where the common design variables correspond to the material properties or geometrical characteristics of the struts used to create the lattice. Some of the optimization tools used include genetic algorithms (GA) (Gazonas et al, 2006;Bilal and Hussein, 2011;Liu et al, 2014), particle swarm optimization (PSO) (Guo and Zhang, 2022;Tikani, Ziaei-Rad, and Moosavi, 2023), bidirectional evolutionary structural optimization (BESO) (Fan et al, 2016), and gradient-based optimization algorithms (Yi et al, 2019;Quinteros et al, 2021a;Cool et al, 2024). Other investigations have implemented multiobjective optimization strategies for phononic materials, considering mass or stiffness restrictions (Dong et al, 2014), the topology of perforated plates (Hedayatrasa et al, 2016b), or phononic plates with tunable band gaps under equiaxial stretch (Hedayatrasa et al, 2016a).…”

Recent advancements in additive manufacturing technologies and topology optimization techniques have catalyzed a transformative shift in the design of architected materials, enabling increasingly complex and customized configurations. This study delves into the realm of engineered cellular materials, spotlighting their capacity to modulate the propagation of mechanical waves through the strategic creation of phononic band gaps. Focusing on the design of sandwich panels with cellular truss cores, we aim to harness these band gaps to achieve pronounced wave suppression within specific frequency ranges. Our methodology combines surrogate modeling with a comprehensive global optimization strategy, employing three machine learning algorithms—k-Nearest Neighbors (kNN), Random Forest Regression (RFR), and Artificial Neural Networks (ANN)—to construct predictive models from parameterized finite element (FE) analyses. These models, once trained, are integrated with Particle Swarm Optimization (PSO) to refine the panel designs. This approach not only facilitates the discovery of optimal truss core configurations for targeted phononic band gaps but also showcases a marked increase in computational efficiency over traditional optimization methods, particularly in the context of designing for diverse target frequencies.

“…Kang et al 17 reformulated the optimal layout design of the space vehicle structure, considering attitude control effort as a topology optimization problem for minimum compliance under constraints on mass moments of inertia. Guo and Zhang 18 connected the structural performance with the material properties and geometrical features in the design process to analyze the mass inertia moment of the zigzag beam-supported. Takezawa et al 19 took the spindle inertia as the design variable and proposed a new structural optimization method.…”

Assembly is an essential part of aero-engine manufacturing, and the assembly quality will affect the engine’s stability and service life. Spindle inertia is an essential factor affecting aero-engine dynamic performance. Assembly can affect the spindle inertia of the aircraft engine, which in turn affects the dynamic performance of the engine. This paper proposes a transfer model of spindle inertia based on machining error transmission, studying the variation law of spindle inertia of multi-stage rotors under the influence of assembly, providing an optimized assembly method with minimized spindle inertia. The influence law of machining errors on spindle inertia is analyzed through the simulation and probability density method. The assembly results of the designed rotors verify the effectiveness of the inertia transfer and assembly model. The results show that the spindle inertia of multi-stage rotors is affected by machining errors, and the spindle inertia can be adjusted by changing the assembly methods. This paper provides a new idea for the transmission and adjustment of spindle inertia of assembly rotors.
