Due to size limits in the transverse direction, tensile testing is not appropriate to investigate the mechanical properties of elytra cuticle of the dung beetle (Copris ochus Motschulsky). However, nanoindentation testing can determine a material’s anisotropic properties through a single indentation. In the present study, nanoindentation stress–strain curves were used to characterize the complete mechanical behavior of dung beetle elytra cuticle. A differential constitutive equation has been developed with time-dependent spring constants k and viscosities η . To describe the complex viscoelastic behavior of dung beetle cuticle, a descriptive representation of the linear viscoelasticity law for the multilayer matrix has been formulated. A qualitative model for the relationship between cuticle structure and mechanical properties of elytra may help develop bionic composite materials for micro-aircraft, bionic tribology, bionic medical apparatus, and bionic organs (tissue engineering).

Aiming the case that vibrations and shocks of micro rescue robot parts caused by the unsmooth locomotion of micro rescue robot, in order to ensure the smoothness of the micro rescue robot trajectory and no collision, eventually to arrive the desired position and orientation, based on the basis of the kinematics and dynamics, according to the micro rescue robot joint movement characteristics, trajectory planning use the D-H method and the track is divided into acceleration, constant speed, and the deceleration three motion segments to discuss, this is of great significance to solve the smooth of micro rescue robot to work in different environments and real-time control and accuracy problems.

The “SG” is a large inertial confinement fusion (ICF) project that is building in china. Its essential working principium is stimulating the nuclear material in the target ball by shooting with laser, then the ICF will produce large numbers of fusion energy which is controllable. The laser is lead and transmited primary by mirror which is clamped by mirror frame in the shooting range system.For the needs of precision when shooting, there are some strict demands to the dynamic characteristics of the mirror frame. This paper designed a machine model of a array mirror frame which is quad intergrated, and simulation analysis on dynamic characteristics of the mirror frame .

Kinematics analysis of mechanism refers to analysis for pose、speed and acceleration of mechanism end manipulator. In this paper, the manipulator of MOTOMAN UP50 is firstly regarded as object, then setting up its pose equation by way of D-H, simulating its kinematics by software of Adams, the real time results of pose、speed and acceleration of robot in different conditions have been obtained. Therefore, it makes sense in kinematic performance of joint robot and prepares for further research of kinetic and controlling properties.

nanomechanical testing system in this paper has been applied to get elastic modulus and hardness of dragonfly wing, and showing their gradient changes along the wing, and also analyzing the mechanical properties in nanodimension. It is significant to make a further research for specific biological functions of dragonfly wing.
