The Structural Design of Friction Energy Dissipation Interceptive Devices with Constant Resistance

Abstract:

In the fields of bridge anti-collision, it is always a headache to protect bridges from being damaged when it is collided by large-tonnage ships. This paper presents a kind of friction energy dissipation device with constant resistance which is equipped with two-way mechanism to exert force and take C/C composite material with high-temperature resistant as the base material of the friction plate which can bring large and constant (high temperature stability) friction force. Then consume the huge impact kinetic energy resulting from the ship’s deviation from the right channel when navigating by doing work of the friction force and transfer this huge kinetic energy into the product of force(friction) and the displacement that cable releases, exchanging energy for space and consuming the huge energy through expanding space, which can get the goal to protect the bridge. What’s more, we have modeled for the key part of the mechanism exerting two-way force and optimized by finite-element analysis method so that the structure of this mechanism is simple, stable and has long service life.
