In this paper, we propose a force feedback scheme for Delta device to improve precision and stability in master-slave teleoperation. A simple and exact dynamical equation is created with principle of virtual work, which is easy to calculate in real-time. After analysing three items deep in dynamical equation, a reasonable strategy is designed to identify the mass of Delta mechanism. The identified...
This paper mainly analyzes the typical compliant flange system and introduces impedance control methods for force tracking. First of all, we establish a compHant system with the internal cylinder of flange, electronic pressure regulator as well as other components, and build the transfer function of the system and verify the stability of the system. Next, we discuss about the model of compliant system...
The influence of viscoelastic behavior of polybutylene terephthalate (PBT) on reliability of the thermal contact of a spotlight module is evaluated. The contact between a module and the heat sink is evaluated using non-linear finite element model. The viscoelastic behavior of PBT was obtained under multiple frequencies from single cantilever DMA experiments. The relevant viscoelastic parameters (i...
