In order to make the quadruped robot walk stably with trotting gait, this paper analyzed the animal's motion to get the rule-based gait sequences and used the half wave functions and cosine functions to plan the functions of every joint combining cyclical motion. Also, on the basis of the obtained gait, the virtual prototype of a bionic quadruped robot was established and kinematic and dynamic simulations were done. The simulation results show that the motion functions can make virtual prototype of the quadruped robot walk stably and the rule-based gait planning method is accurate and reasonable.

With the applied development of Cam mechanism in modern civilization, the running speed of cam mechanisms is increasingly high , the inertial force of system follower raced up.Dynamic analysis and dynamic design must be considered when analyzing high-speed cam mechanism. This article takes combustion engine high-speed Valve cam for example, adopt cyclical motion rule when calculating , follower system would be equaled to Single freedom dynamic model and movement equation would be established. Meanwhile, establishing the movement equation . Use MATLAB to work dynamic response change curve to obtains the different period ratio to push the regulation sector principal oscillation response and ttop the secto sor hangover response far the influence, thus makes the explanation to the period ratio reasonable choice.

The coating and encapsulating of particles presents many applications in the chemical, pharmaceutical, food and agricultural products industries. Among the many applications of seeds coating, the enlargement of small seeds is included in order to facilitate the planting, the addition of herbicides, fungicides, fertilizers, micronutrients and inoculation. The spouted bed has often been used in studies related to the coating of particles, due to the cyclical motion of the material, which promotes a fast axial mixture of particles and an excellent gas-particle contact. In this work, the coating of soybean seeds with inoculum and micronutrients in spouted bed has been studied. The different flow regimes were investigated using the pressure fluctuations and power spectrum. The results of the present work showed that it was possible to identify the main flow regimes and to analyze the influence of the coating in the stability of those regimes.

A model is suggested for the continuous description of cyclical motion. The model is an application of the sinus equation and derives from the selection of a representative point of a bodily part for which movement is to be described, the identification of a reference axis, and the continuous representation of time. Although restricted to cyclical motion, the model seems useful for describing many behaviors of quite different species by means of the same descriptive elements.
