Manipulating large numbers of a variety of particles/wires is essential for many lab-on-a-chip technologies. Here we generate a planar array of optofluidic vortices with photothermal gradients from an easy-fabricated graphene oxide (GO) heater to achieve high-throughput and multiform manipulation at low excitation power and low loss. As a tweezer, each vortex can rapidly capture and confine particles...
The dynamic model of a multi-axis synchronous gantry machining center VX32-60 is developed based on the finite element method. Both the numerical simulation and the modal experiment are studied. The nature frequencies and mode shapes are obtained by theoretical analysis and experimental results. The effects of material parameters and section parameters on the dynamic characteristics of multi-axis...
A flexible dynamic model of a multi-axis synchronous gantry machining center was developed with a finite element analysis software SAMCEF Mecano. The dynamic solution was obtained with implicit Non linear method and HHT recurrence algorithm based on modified Newmark algorithm. The position error and velocity were analyzed. The influence of elastic deformation on position error was developed contrast...
