Abstract
A ship model inertia regualting frame is composed of supporting unit and swinging unit. Its connection manner is characterized by that both units are lap-jointed via the carriers of supporting unit and the blades of swinging unit. It can be used to regulate the gravity center position of ship model, measure its rotation inertia, and measure the rotation period.
Description
Technical field
What the present invention relates to is a kind of adjusting bracket, and particularly a kind of ship model inertia adjusting stand belongs to field of measuring technique.
Background technology
After ship model completes, need to regulate weight, center of gravity, the moment of inertia of ship model, the Sihe mass distribution is similar mutually to guarantee quality with actual boats and ships.The weight of ship model is debugged by the increase and decrease foundary weight according to the size of water discharge.Center of gravity and moment of inertia adopt suspension method to connect measurement in the ranks in that the ship model adjusting bracket is enterprising usually.The method of traditional measurement inertia is to utilize three string pendulums to measure, some frame measuring instruments are also arranged, and these survey instruments do not have the function that the integrated quality characteristic is regulated because size is less than normal, and the common measuring method and the systematic error of instrument are too big, so can not satisfy the needs that ship model is measured.Find by literature search, people such as Wu Bin are in " Shanghai space flight ", deliver " design of guided missile mass property measurement mechanism " literary composition on the 3rd phase of calendar year 2001, this article has been introduced the mass property of guided missile and has been measured a kind of integrated measurement mechanism that uses, but this device can not satisfy the Testing requirement of ship model mass property, be mainly reflected in the following aspects: (1) guided missile model and ship model are at volume and be not an order of magnitude qualitatively, the weight of ship model is between hundreds of kilogram to two ton, so need measurement mechanism to have enough physical strengths to support the weight of whole ship model, to keep the barycenter of total system lower simultaneously, to guarantee that enough stability is arranged, these require the measuring system of guided missile to satisfy.(2) content of the mass property of the mass property of ship model and guided missile is different, the moment of inertia of moment of inertia in the mass property of guided missile and ship model mass property around the axle different.(3) the ship model inertia survey instrument requires not only can measure, and can on this survey instrument, regulate, make the mass property of ship model meet experimental requirements, and the mass property measurement mechanism of guided missile only is to measure fixing guided missile mass property.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and defective, a kind of ship model inertia adjusting stand is provided, make several functions such as measurement of its disposable integrated adjusting of centre of gravity place, moment of inertia, the problem of physical strength aspect can not appear in whole device when bearing large-scale ship model, maintainable good, convenient disassembly.The present invention is achieved by the following technical solutions, and the present invention is made up of support section, swing part two parts, and its connected mode is: support section and swing part are by the knife rest of support section and the edge of a knife lifting overlap joint of swing part.
Support section comprises: anchor post, pitching pillar, knife rest, base, rolling pillar, its connected mode is: each is provided with pitching pillar, anchor post, rolling pillar by the centre successively to two ends the both sides of base, top at the pitching pillar is provided with knife rest, and the support section of whole adjusting bracket is symmetry all around.Swing part comprises: the edge of a knife and cradle, and its connected mode is: cradle is provided with the edge of a knife, and cradle is arranged on the knife rest of pitching pillar.
Base is used to bear the weight of total, because the weight of base self is bigger, so can keep integrally-built weight center on lower position, is beneficial to the stability that keeps whole.Knife rest is placed on the top of pitching pillar, is used for Adjustable supporter when measuring vertical inertia.Knife rest contacts with the edge of a knife, damping minimum when cradle is swung on the edge of a knife.Pitching pillar when the rolling support function is equal to pitching.Cradle is used to hold ship model.The edge of a knife can reduce damping as the link of cradle and support section with the edge of a knife, and is beneficial to the loading and unloading of cradle.Anchor post prevents the adjusting bracket swing when mobile foundary weight.
During use, ship model weight is carried out the weight adjusting according to the size of water discharge by the foundary weight of placing in the increase and decrease ship model, and everything carries out on weighbridge.After ship model weight is regulated and finished, the edge of a knife of the cradle of adjusting bracket aligning is placed on the knife rest of pitching pillar, utilizes anchor post that cradle is fixed and do not make its pitching, ship model is hung in cradle with gantry crane.After placement was finished, the longitudinal center of gravity of the ship model of testing requirements was on the line of two edges of a knife, and anchor post rotation unsettled makes cradle can carry out pitching.Surveyor's staff is placed on the edge of cradle, regulates the position of the foundary weight in the ship model, cradle is up to the standard, this moment, the longitudinal center of gravity of ship model was desired position.Surveyor's staff is taken away, cradle and ship model are vertically freely rotated, measure cycle of its swing, regulate the vertical position of foundary weight in the ship model, make the requirement of Pass Test hunting period, then the position consistency of the vertical position of ship model center of gravity and testing requirements with stopwatch.All regulate in the process of foundary weight must with anchor post fixedly cradle in order to avoid rock.Can calculate the required amount of test with corresponding formulas according to the data of measuring.
The present invention has substantive distinguishing features and marked improvement, and the model that the present invention has overcome other survey instruments measurements is little, the defective that measure physical quantities is single.In addition, the support section of this adjusting bracket can separate with rotating part, helps the lifting of ship model, can adjust the ballast in the object and utilize anchor post that swing part is fixedly regulated in adjusting.The disposable integrated adjusting of centre of gravity place, several functions such as the measurement of moment of inertia, be mainly used in the adjusting of ship model moment of inertia in the Naval Architecture and Ocean Engineering experiment, ship model weight, the adjusting of center of gravity is with definite, the measurement of rotation period etc., also can be used for automobile, space flight, navigation, the rotation inerttia of the empirical model of war industry equipment and other mechanical engineering aspects, weight, the adjusting of center of gravity is with definite, the measurement of rotation period etc., the present invention has saved the cycle of experiment, improved the precision of experiment, save experiment fees, can obtain good scientific research and economic benefit.
