Mechanics of solidsThe basic solution of two parallel mode-I permeable cracks in functionally graded piezoelectric materials was studied in this paper using the generalized Almansi's theorem. To make the analysis tractable, it was assumed that the shear modulus varies exponentially along the ...
Cable-driven parallel robot (CDPR) is a type of high-performance robot that integrates cable-driven kinematic chains and parallel mechanism theory. It inhe
First, from the perspective of bionics and mechanics, this paper adopts the parallel scheme of the horizontal layout of the driving end and the concepts of lightweight and modularization and designs a quadruped robot with low self-weight, simple structure, and high transmission performance. In the...
The sampling frequency used in the experiment was 640 Hz; therefore, it met the sampling theorem, and the collected signals were reliable. The time-domain curves of the excitation and vibration signals collected during the experiment are presented in Figure 9. Figure 9 Time domain curve of the...
We have developed an open-source software package, Open-source Seismic Wave Propagation Code (OpenSWPC), for parallel numerical simulations of seismic wave propagation in 3D and 2D (P-SV and SH) viscoelastic media based on the finite difference method in local-to-regional scales. This code is...
In structured light tweezers, it is a challenging technical issue to realize the complete circular motion of the trapped particles parallel to the optical axis. Herein, we propose and generate a novel optical skipping rope via combining beam shaping technology, Fourier shift theorem, and beam grafti...
To analyze the rigid–flexible coupling effects on the dynamic performance of a robot system, a dynamic model of a parallel robot with flexible spatial links is derived in detail using a floating frame of reference (FFR) formulation. Compared to the previous rigid–flexible coupling model where ...
