In the mechanized harvest of vines, grape berries are detached through the vibration to the structure supporting the clusters. According to the kind of guide selected, the clusters require one or two vibration directions in the structure. For guiding in parral structures, vibration is necessary in two directions or planes: One perpendicular to the other. The guide branches producing the clusters develop in these planes, and the guiding is called H-guiding. Mechanism theory indicates that a mechanism has as many degrees of freedom as its actuators, and an actuator is needed to achieve a certain vibration. Having the smallest number of possible actuators is beneficial in reducing moving parts and achieving more compact and easily controllable mecha-nisms. In this case, a single degree-of-freedom mechanism is proposed. It is capable of generating vibrations on two planes: One perpendicular to the other. This mechanism is the sum of two link mechanisms on perpendicular planes with a common outlet located at the output rod of the mechanism where the actuator is found. As the distance between the soil and the elements containing the clusters is not constant, a system has been designed to measure the accelerations at the bars and the rocker to validate the acceleration values that detach the grape berries in a prototype in a lab experiment, to ensure that the acceleration needed for pulling the grape berries are produced at any contact point of the bar.

以淀粉基水性高分子异氰酸酯(API)胶合木胶接结构为研究对象,以胶接的压缩剪切强度为评估指标,通过加速湿热老化试验对胶接结构的破坏模式和失效机理进行了研究。结果表明:胶接结构的断裂性质为韧性断裂,且随着老化时间的增加,其破坏模式为由内聚破坏向内聚破坏+界面破坏转变。在湿热老化试验前期温度对压缩剪切试样性能起主要作用,在老化后期湿度起主要作用。
