Description
Technical field
The present invention relates to mould measurement experimental field, especially a kind of teaching is filled with the experimental teaching of plate mould measurement
It sets.
Background technique
Current each colleges and universities for offering automobile engineering speciality offer corresponding mode experiment course, all refer to
The mode of material measures knowledge.But rarely related matching used impart knowledge to students uses mode experiment measuring tool, institute on the market at present
The experiment of progress is some easy restraint devices of assembling mostly.This causes constraint condition and ideal constraint difference larger, experiment
The error of measurement result is not easy to control.Therefore, even if having opened up corresponding mould measurement experimental courses, also more difficult visual pattern
Student is enabled to understand the process of mode measurement.In order to solve existing suggestion mode experiment equipment it is too simple and cause experimental error compared with
Big status, the present invention provides a kind of plate mode experiment instructional device, the measurement which can not only be accurate is not
With the Free Modal and Constrained mode of plate, additionally it is possible to convenient to place experiment test plate.
Summary of the invention
Present invention is generally directed to propose a kind of teaching plate mode in the shortage for solving current mode experiment teaching equipment
The measurement of plate Free Modal and Constrained mode may be implemented in measurement experiment instructional device, the cart, and includes safety knot
Structure, constraint is accurate, portable construction, is easy to assemble and disassemble maintenance, long service life, safe and reliable.
In order to meet the above requirements, the technical solution that the present invention provides are as follows: the single layer chassis include crossbeam, stringer,
Hand and brake caster.Single layer Undercarriage structure is welded by two crossbeams and five stringers.Cart handle is welded on chassis side
On crossbeam.Brake caster is mounted below four angles of chassis by fixed device, using the side of rubber outer ring and metal wheel hub
Formula combination, has biggish bearing capacity is gentle to rush shock sucking function, is furnished with lockable mechanism thereon, can mode measurement experiment into
Cart is set to be in static stable state when row, to ensure the accuracy tested.
The bracket includes not equal diameter pillar and test board storage shelf, does not have the shaft shoulder on equal diameter pillar, with bearing
Stablize support, a L-type hook is also welded on pillar.Storage shelf is placed on chassis, and both ends are provided with incised groove,
In order to store test board.
The clamp mount includes stablizing support, Free Modal laboratory holder, Constrained mode laboratory holder and damping unit
Support, wherein stable support is divided into removable parting and two kinds of non-disconnectable parting.Non-disconnectable parting stablizes branch cover for seat in the pillar
At the shaft shoulder of the top, removable parting stablizes branch cover for seat at the shaft shoulder in the middle part of the pillar, is locked at branch by bolt and nut
On column, two kinds of stable supports have the dovetail groove of cooperation steady rest；The detachable set of damping unit support passes through spiral shell below pillar
Bolt nut check is on pillar；Free Modal laboratory holder is detachable, and is mounted on above the stable support of non-disconnectable parting and passes through
Bolt and nut is locked on pillar, and by the stable bearing support；Constrained mode laboratory holder is detachable, and is mounted on detachable
Type, which is stablized, to be locked on pillar above support by bolt and nut, and by the stable bearing support；Damping unit support is removable
Stablize the lower section of support in removable parting, and is locked on pillar by screw nut.
The steady rest includes four vertical poles and cross bar, is evenly arranged on stable support.Using upper layer and lower layer rock-steady structure, with
The rigidity that the stability and Constrained mode for improving the pillar constrain when testing.Upper layer rock-steady structure by two kinds of stabiliser bars with
Non-disconnectable parting is stablized support and is coupled, and lower layer's rock-steady structure is stablized support cooperation by two kinds of stabiliser bars and removable parting and pacified
Dress.Cross bar, vertical pole both ends have the tenon of dovetail, by way of tenon connection by the steady rest be installed to stablize branch
On the dovetail groove of seat.
The safe fagging assembly includes one piece of safe fagging, four damping units and four connecting suckers.Damping unit
It is in mating connection with the damping unit support that is mounted on the pillar；Four connecting suckers are evenly arranged on safe fagging,
And connect by shaft with damping unit, to support safe fagging.
The present invention has following advantages: the steady rest is divided into upper layer and lower layer, and installation site is close to the mode experiment
Fixture, with good stability and enough constraint rigidity.
The mode experiment fixture is spatially separated by, and Free Modal laboratory holder is arranged in the top of pillar, constrains mould
State laboratory holder is arranged in the middle part of pillar, avoids while cause when both modalities which measurement experiment Board Under Test, test to use
The interference of the equipment such as acceleration transducer, pickup wire.
The Free Modal laboratory holder has used pulley, and experimenter is facilitated to suspend tested test plate (panel) simultaneously using flexible strand
And adjustment is horizontal, flexible strand can be fastened directly on L-type hook.
The fixed tested test plate (panel) of bolt is tightened in the mode experiment fixture use, is adapted to certain thickness range plate,
To guarantee that constraint is reliable.
The safe fagging assembly can be adjusted within a certain range its height, so that it evades close to tested test plate (panel)
Be likely to occur when installing tested test plate (panel), cause test board to fall due to personnel's careless manipulation, and then injure the peace of personnel by a crashing object
Full hidden danger.
The present invention largely uses metal pipe material and sheet metal to be welded, and used fixture uses cast iron, cast aluminium
Material, therefore the gross mass of experimental teaching unit is light, conducive to the carrying of experiment equipment, simultaneous processing cost is reduced, and it is easy to use,
Maintenance is simple, is conducive to popularize in colleges and universities' mode measurement experiment teaching.
