In this paper, we propose a new component mode synthesis method by enhancing the Craig–Bampton (CB) method. To develop enhanced CB method, transformation matrix of is considering effect residual substructural modes and unknown eigenvalue in approximated using O'Callahan's approach Guyan reduction. Using newly defined matrix, original finite element models can be more accurately reduced models. For reason, accuracy significantly improved with low additional computational cost. We here present...
Abstract Ambient vibration energy is highly irregular in force and frequency. Triboelectric nanogenerators (TENG) can convert ambient mechanical into useable electricity. In order to effectively vibrations electricity, the TENG should be capable of reliably continuous operation despite variability input forces frequencies. this study, we propose a tandem triboelectric nanogenerator with cascade impact structure (CIT-TENG) for continuously scavenging broadband Based on resonance theory, four...
Component mode synthesis is a popular reduced-order modeling technique with substructuring strategy in structural dynamics. The ideal goal of component to construct compact reduced models adequate accuracy for specific intended applications. In this paper, five priori selection methods plus an posteriori method have been evaluated as applied several representative dynamics problems assess their relative merits. present evaluation offers guideline the informed use these methods, and it hoped...
As the smart mobile device market continues to grow and number of cameras per rapidly increases, demand for CMOS image sensors (CIS) also increases. Two major trends in are: (1) adopting smaller pixels that enable greater pixel count at similar optical format, (2) bigger higher quality. To be more specific, front-facing have a trend towards pixels, while rear main both pixels. The format is especially limited due existing bezel-less or border-less display designs, yet resolution still-shot...
Abstract Corrosion properties of three different Sn‐Ag lead free solder alloys have been investigated in 0.3 wt% Na 2 SO 4 solution as corrosive environment. As cast alloy was analyzed by X‐ray diffraction (XRD) and scanning electron microscopy (SEM). Volume fractions the Ag 3 Sn solders were determined image analysis technique. Pitting potential corrosion for potentiodynamic tests. Electrochemical impedance spectroscopy (EIS) carried out to measure film charge transfer resistance. Alloys...
Summary In this study, we propose an effective method to estimate the reliability of finite element models reduced by automated multi‐level substructuring (AMLS) method. The proposed error estimation can accurately predict relative eigenvalue errors in models. A new, enhanced transformation matrix for AMLS is derived from original properly considering contribution residual substructural modes. important prerequisite develop Adopting basic concept recently developed Craig–Bampton method,...
