The platform of a hexapod is a part of the structure whose six degrees of freedom are constrained by six linearly independent line constraints. The six line constraints are utilized for developing simply supported, ”joint less” connector configuration for the transmission of axial forces. Six beam transducers are utilized to serve as a base of a hexapod structure. The applied wrench information is obtained by measuring the six forces on the beam transducers at the fixed base. The idea of “joint less” structure and beam transducers resolve issues of precision and sensitivity in measuring a very small wrench. The validity of the design is proved by developing a prototype sensor as well as conducting various experiments. The results of the experiments are discussed in detail. 相似文献

In the conventional valve-controlled hydraulic elevator, when the cabin moves downwards, the entire potential energy of the cabin is wasted and converted into fluid heat by throttling. Thus, the energy consumption of a traditional hydraulic elevator is much higher than that of the traction elevator. To reduce the energy consumption and power installation requirements, the energy-regenerative hydraulic elevators have been developed since 1997. In this paper, different generations of the design are discussed for energy-regenerative system; in particular, a new generation is focused on in detail. Experimental studies of this new design are carried out to compare the energy consumption of different system designs of hydraulic elevator. Finally, a conclusion is drawn that the new generation of hydraulic elevator can achieve a significant energy-saving performance compared to the traditional elevators. 相似文献

In this paper, the design and development of a six degrees-of-freedom (DOF) reconfigurable gripper for implementation of robot based flexible fixtureless assembly (FFA) is described. FFA is a novel technique in which traditional fixtures used, for example, in automotive body assembly industries, are eliminated by the use of several robots, with multifinger grippers that are used to grasp and assemble parts. The objective of this work is to design, build, and test a reconfigurable gripper for the purpose of FFA. The gripper developed in this work is capable of precisely grasping parts of different geometries, rigidly holding the parts in space, and choosing different grasping points while allowing sufficient clearance for welding gun access. The overall design procedure, which is subdivided into the conceptual, configuration and parametric design, includes wrench system determination, kinematic and mechanism design. A novel three-finger gripper is developed. Each finger has two movable joints and two point-contacts with which to grasp the part. Finite element analysis is used to simulate deflections of the gripper components under load to determine critical design parameters. Finally, the workspace and the kinematic model of the reconfigurable gripper have been developed. The gripper was fabricated and tested in grasping experiments using several automotive body panels. The reconfigurable gripper is shown to achieve the objectives set out in this work. 相似文献
