Earthworm-like robots have received great attention due to their prominent locomotion abilities in various environments. In this research, by exploiting the extraordinary three-dimensional (3D) deformability of Yoshimura-origami structure, state art earthworm-like is significantly advanced enhancing capability from 2D 3D. Specifically, introducing into virtual creases, kinematics non-rigid-foldable Yoshimura-ori structure systematically analyzed. addition exhibiting large axial deformation,...
Origami-based mechanical metamaterials and metastructure have been demonstrated to exhibit unique properties originating from their intricate geometries of folding. This research aims extend the current investigation level quasistatics dynamics. In detail, this focuses on wave dynamics a composed stacked Miura-origami (SMO) units. The SMO unit could possess two stable configurations, endowing with rich possibilities in layout its periodic repeating cell. Through linear dispersion analyses...
232Th/233U fuel cycle is an alternate candidate for future nuclear energy. Neutron-induced fission cross section of 232Th one the important data if using thorium as in future. 232Th(n, f) sections from 1 to 300 MeV were measured at China Spallation Neutron Source (CSNS) Back-streaming neutron facility (Back-n) relative 235U(n, and n-p scattering. A fast ionization chamber measurement (FIXM) a proton recoil telescope (PRT) used perform measurement. The energy this reaches up which supposed be...
Herein, this study contributes significantly to the advancement of continuum manipulators in two main aspects. First, a modularization concept and hybrid actuation scheme create novel origami manipulator with exceptional deformability are introduced. Second, an accurate model framework for forward inverse kinematic analysis proposed. Specifically, each module can achieve axial extension bending deformation by coordinated shape memory alloy (SMA) pneumatic muscles, manipulator's end is...
Modal identification aims at identifying the dynamic properties including natural frequency, damping ratio, and mode shape, which is an important step in further structural damage detection, finite element model updating, condition assessment. This paper presents work on investigation of characteristics a long-span cable-stayed bridge-Sutong Bridge by Bayesian modal method. Sutong second longest bridge world, situated Yangtze River Jiangsu Province, China, with total length 2 088[Formula:...
Phase structure, microstructure, and microwave dielectric properties of Ba 0.4 Sr 0.6 TiO 3 –Mg B 2 O 6 composite ceramics fabricated by solid‐state reaction were investigated. The results show that the sintered at only 1100°C exhibited promising properties. constant can be adjusted in range from 326 to 90, while maintaining a relatively high tunability 21% 11% under direct current electric field 60 kV/cm Q values more than 200 gigahertz frequency region.
The origami-based meta-structure has wide application in areas such as energy and wave transmission. Existing research demonstrated the occurrence of supra-transmission origami meta-structures revealed its underlying mechanism. However, studies on how to regulate phenomenon are still very limited. In this work, we choose composed stacked-Miura ori (SMO) subject. SMO unit possesses two topologically distinct stable configurations, enabling possess a rich variety periodic layouts. Based...

Integrated health monitoring (HM) systems have been designed and installed in some long-span bridges around the world. One of fundamental objectives a bridge HM system is to gain comprehensive knowledge structural condition, usually it required that early-stage damage detected within monitored information. Yet performance technology has not evaluated practice. The focus this paper investigate applicability current for abnormality alarming. deterioration defects found from 16 cable-stayed are...
Precast buildings have been becoming popular in China these 5 years since they many merits such as effectiveness, safety, high quality, and environmental friendliness. In some cities of China, it is required to make the proportion precast account for 30% newly built construction areas. Following rapid development, their vibration behaviors are attracting more attention may be quite different from cast-in-situ building. To investigate difference, this paper studies modal properties two kinds...
