Description
Technical field
The present invention relates to the acting force measurement mechanism that a kind of pile for outstanding liquid level streams test.
Background technology
While walking around orthogonally the object such as the various gate piers of giving prominence to liquid level and pile when liquid stream as current, object will be subject to streamwise stream resistance and perpendicular to the horizontal lift effect of flow direction.When pile tilts or liquid stream during with the pile oblique, the acting force acted on pile shows as: the acting force of streamwise, perpendicular to pile axially with come the transverse force of flow path direction and the acting force axial along pile.Can be decomposed into accordingly pile detour flow power: streamwise and perpendicular to pile stream resistance, perpendicular to carrying out the axial horizontal lift of flow path direction and pile and the axial power along pile.Due to pile Characteristics of Flow Around complexity, also be difficult at present directly calculate and solve theoretically.The research that pile streams is mostly still by means of numerical simulation and physical experiments, the accurate measurement of streaming resistance, lift and axial force that when wherein tilting pile or liquid stream is with the pile oblique, pile is subject to, stream physical model test for the pile of giving prominence to liquid level particularly important.
When measuring the pile detour flow power of outstanding liquid level, need to guarantee that measurement mechanism can not disturb fluid to flow.The acting force measurement mechanism that the vertical pile of current existing outstanding liquid level streams test mainly contains three kinds: the first is that the pile top is connected with buoyancy aid, utilize the buoyancy of buoyancy aid to make to leave little gap at the bottom of pile and canal, and a power transmission rigid frame is installed on pile, detour flow power is passed to dynameter, measured the size of this power by dynameter.Buoyancy aid in this device is prone to fluctuation under non-uniform flow and unsteady flow condition, harsher to Test Condition Requirements, and can only record the resistance that streams on vertical pile horizontal direction, and can't record the oblique fluid, act on acting force and the mobile detour flow power of non-constant fluid on the vertical direction on pile.The second is to leave one section groove at the bottom of canal, the pile installation component is placed in to groove, the pile installation panel flushes with bottom land, pile is arranged on panel, and liquid stream passes to by the power transmission rigid frame member more than liquid level the dynameter that is placed in whole framework front or back to the impact forces of pile.This device needs bottom land to reserve groove, and there is frictional resistance in panel when operation bottom land, and the size of friction force changes with the variation of different flow and the depth of water, and the impact of friction force is difficult to quantize.This device can't be measured acting force and the mobile detour flow power of non-constant fluid on the vertical direction that pile is subject to equally.The third is meet the stream side and carry on the back the stream side pressure transducer respectively is installed symmetrically at pile to be measured, to measure the resistance that streams of streamwise that vertical pile is subject to, at Vertical Pile capital end, a tension-compression sensor is installed, is flowed to oblique fluid in plane with measurement liquid stream and act on the acting force on the vertical direction on pile.The force signals that sensor records is inputted registering instrument after amplifier amplifies, and can obtain by registering instrument liquid stream that pile is subject to and flow in plane the dynamic changing process of liquid stream acting force on level and vertical direction.The vertical pile that this device can be used for measuring outstanding liquid level horizontal incoming flow or with the oblique crossing liquid stream of pile and the detour flow power of non-constant liquid stream.And above-mentioned three kinds of measurement mechanisms all can not stream resistance and pile axial action force measurement in level or the oblique pile that flows down for tilting pile.
Yet, the problems such as acting force that while for the overfall dam dam facing, baffle pier being set, current are subject to the effect of hydraulic structure and the cylinder on ponding slope, city and step or pedestrian current in the effect of baffle pier, slope rivers and canals, cylinder (or other by streamed object) is not vertically but in tilting state, and in these cases, liquid flows to toward being unsteady flow, and the acting force measurement of the test that current existing measurement mechanism streams at level or the oblique liquid stream flowed down for tilting cylinder (or other is streamed object) is restricted.
