Abstract
The utility model discloses a pier flexibility ship collision resistance experimental apparatus which comprises a closed inner steel surrounding part and a closed outer steel surrounding part which are sleeved outside a pier. A plurality of anticollision rings which are uniformly distributed are fixedly connected between the inner steel surrounding part and the outer steel surrounding part. The pier flexibility ship collision resistance experimental apparatus is characterized in that a force body is arranged on the outer steel surrounding part; a plurality of first force cells which are distributed in an array mode are respectively and fixedly arranged on the rear surface and the lower surface of the force body; the first force cells are fixedly connected with the outer steel surrounding part; and second force cells are fixedly arranged at the connecting ends of the anticollision rings and the inner steel surrounding part. The pier flexibility ship collision resistance experimental apparatus has the advantages that by the experimental apparatus, real ship collision data can be obtained so as to further correct a computational model, improve the simulation accuracy of a collision value and provide powerful basis and reference for designing and researching a flexibility anticollision device; the first force cells on the rear surface and the lower surface of the force body are distributed in an array mode, so that a large force measurement area is implemented and the requirement on the accuracy of an experimental ship collision position is reduced.
Description
Technical field
The utility model relates to the study if of the anti-ship collision device of bridge pier, relates in particular to the flexible anti-ship collision experimental provision of a kind of bridge pier.
Background technology
In the accident of ship collision bridge,,,, the safety of bridge is brought very big problem so the kinetic energy of ship collision bridge pier is very big because other vehicles of weight ratio of boats and ships want big many though the speed of wrecked ship is generally slow than other vehicles.And in order to prevent that the design ability to bear that surpasses bridge pier because of ship impact force from causing bridge to damage, the anti-ship collision device of various bridge piers constantly occurs.The flexible anti-ship collision device of bridge pier is a kind of novel pier anticollision facility, its crashproof theory be not only can absorption portion Impact energy, can also change the course of boats and ships, make boats and ships take away most kinetic energy, thereby reduce the impact of boats and ships greatly bridge pier.This flexible protective device can obtain fabulous crashproof effect usually, and its cost is also relatively low.Numerical simulation has also proved this analysis result to a certain extent.But; Because the uncertain factor in the collision process is a lot, presses for through real ship striking experiment and obtain real bump data, so that further corrected Calculation model; Improve the collision simulation precision, quicken applying of the flexible anti-ship collision technology of bridge pier.
Summary of the invention
The utility model technical matters to be solved is a kind ofly to obtain to clash into data really so that further revise the flexible anti-ship collision experimental provision of the bridge pier of design.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the flexible anti-ship collision experimental provision of a kind of bridge pier; Comprise that the airtight interior steel that is enclosed within outside the bridge pier encloses and outer steel encloses; Steel encloses and outer steel is fixedly connected with a plurality of equally distributed anti-collision rings between enclosing in described; Described outer steel is placed and is provided with beaer; Be set with a plurality of first force cells that are array distribution on the back surface of described beaer and the lower surface respectively, described beaer internal fixation is provided with latticed ribs, and the installation site of described first force cell is positioned at right-angled intersection place of described ribs corresponding end; Described first force cell encloses with described outer steel and is fixedly connected, and described anti-collision ring and described interior steel enclose and be set with second force cell on the link.
Steel encloses with outer steel and is filled with the high strength polyfoam respectively in enclosing in described, has guaranteed experimental provision after by multiple impact, leaks and can not sink just in case break.
The material of described anti-collision ring is a rubber.
The principle of work of this experimental provision is: when testing the front surface of ship collision beaer; Steel was placed in impact was delivered to through the anti-collision ring that connects inside and outside steel and enclose; And finally be delivered to impact on the bridge pier; Flexible anti-ship collision device transmits, disperses impact in knockout process, and dials and change direction of ship travel.And in this knockout process; Be decomposed into horizontal Fx to ship impact force and note with first force cell on the lower surface on surface behind the beaer by the vertical coordinate system arranged in arrays with vertical Fz component form; And through making a concerted effort formula:
can calculate the impact of boats and ships; Simultaneously the second force cell energy measurement on the anti-collision ring goes out its stressed time-history curves, for the Change In Design of anti-collision ring provides foundation.
Compared with prior art; The utility model has the advantages that through this experimental provision and can obtain real ship collision data; So that further the corrected Calculation model improves the collision simulation precision, for the research of flexible protection Design of device provides strong foundation and reference; And the back surface of beaer and the employing of first force cell on lower surface array distribution, realized big dynamometry area, reduced requirement to experiment boats and ships impingement position precision.
