Abstract: The present invention belongs to the technical fields of novel structure design and lattice material design, and refers to structures, lattice materials, and lattice cylindrical shells with simultaneous stretch- and compression-expanding property. First, use the local tension-compression asymmetry in the tension modulus and compression modulus generated by the contact nonlinearity of the tension springs to construct a type of 2D structures and lattice materials with stretch- and compression-expanding property. Then by assembling the 2D structures in different directions, 3D structures and lattice materials can be constructed. Meanwhile, a lattice cylindrical shell can also be constructed by using the 2D stretch- and compression-expanding structures as the unit cell. The structures and lattice materials presented in this invention can be used as a specific functional material and has a promising application in the fields of energy absorption, vibration reduction, medical treatment, wave propagation, intelligent components, and so on.

Abstract: A wave energy thermal storage type seawater thermoelectric power generation device which comprises a buoy-type energy capture system, a platform system and a mooring system. A whole friction liquid heating, thermal storage and power generation device is arranged inside a platform, which improves the adaptability of the whole system to the external environment. A flywheel and liquid friction heating method is adopted to generate heat more efficiently. Inner ratchets and pawls are used to control the movement of a flywheel so that the flywheel always rotates in one direction, and when the rotating speed of the flywheel exceeds that of the inner ratchets, the external wave energy cannot be transferred to the flywheel through the movement of the inner ratchets so as to limit the upper limit of the rotating speed of the flywheel and protect the safety of the flywheel system.

Abstract: A digital image measurement device and method for the surface deformation of specimen based on sub-pixel corner detection is disclosed. This digital image measurement device is composed of a new type of image pressure cell, a complementary metal-oxide-semiconductor (CMOS) camera, a camera bracket, a flexible lens hood, a computer and matching measurement software. This method discretizes the specimen into several four-node finite elements by printing grids on the specimen and takes corners of the grids as the nodes of the finite elements; tracks the deformation of the feature points in real time by edge detection and corner detection based on sub-pixel; captures the deformation of the whole surface of the specimen by the two flat mirrors which are at an 120° angle behind the specimen; achieves the observation of the deformation of the whole surface by conducting splicing and error correction on the three images.
