According to the principle and the basic concept of vortex-induced vibration, this paper deduces the vortex-induced vibration of cable vibration partial differential equation, the floating tunnel body section is simplified to the influence of parametric excitation generation into the equation. Then consider the tunnel - cable coupling model more realistic response are obtained. By changing the parameters,...
Aiming at the mechanism of enterprise production equipment accidents, the workshop equipment safety evaluation index structure system based on knowledge management was proposed. And a fuzzy comprehensive evaluation model for workshop equipment security forewarning method was established .The manpower, machine, materials, methods, information and environments in the workshop production site management...
