Abstract
The utility model relates to a tired endurance test device of balanced inertial force, including bottom plate, sliding guide, slide bracket and actuating mechanism, sliding guide establishes on the bottom plate, and slide bracket establishes on sliding guide, and actuating mechanism and slide bracket are connected, and actuating mechanism includes the buncher of adjustable frequency and can change the crank connecting rod of length that slide bracket sets up slide bracket 0 along the both ends of direction of motion in pairs. Compared with the prior art, the utility model discloses a set up extension spring in pairs as elastic buffering mechanism at slide bracket, balanced inertial force reduces the inertial force effect, eliminates inertial force and to measuring the harmful effects that produce, reaches the steady of slide bracket motion, take the dull and stereotyped conduct slide bracket of the light fretwork of quality simultaneously, further reduce inertial force, guarantee that the device operates steadily, device simple structure, strong adaptability changes swiftly, is convenient for implement.
Description
Technical field
The utility model is related to a kind of fatigue endurance system safety testing device, more particularly, to a kind of the tired resistance to of balance inertial force
Long system safety testing device.
Background technology
Parts on automobile or other equipment are required for certain fatigue durability requirement, and parts endurance quality is tested
It is necessary, test is generally carried out by test-bed.It is as parts specification is more, test request differs, rack-mounted to testing stand
Put, also need reliable and stable running, it is ensured that test is smoothed out.Existing measurement dress
The subject matter for putting presence be sliding platform when moving reciprocatingly, can produce inertia force effect, inertia force cyclically-varying,
Test-bed device will be caused to produce forced vibration, inertia force is bigger, and the vibration of generation is bigger, affect the stable fortune of test-bed
Row and the accuracy tested, even resulting in device cannot run.
Utility model content
The purpose of this utility model is exactly to provide a kind of fatigue durability of balance inertial force to solve the above problems
Test device.
The purpose of this utility model is achieved through the following technical solutions：
A kind of fatigue endurance system safety testing device of balance inertial force, including base plate, rail plate, sliding platform and driving
Mechanism, described rail plate are located on base plate, and described sliding platform is located on rail plate, described drive mechanism and cunning
Moving platform connects, and described drive mechanism includes the buncher of adjustable frequency and can change the crank connecting link of length, institute
The sliding platform stated is arranged in pairs elastic buffering mechanism along the two ends of the direction of motion.
Described elastic buffering mechanism adopts elastic adjustable extension spring.
Described extension spring one end is fixed on base plate, and the other end is fixed on sliding platform.
Described crank connecting link one end is fixed on sliding platform, and the other end is connected with buncher.
Hollow out flat board of the described sliding platform using light weight, sliding platform are slided along the direction of motion on rail plate
It is dynamic.
Base plate when in use, is fixed in exemplar one end by this device, and the other end is fixed on sliding platform, in motor and song
In the presence of handle connecting rod, sliding platform moves reciprocatingly, and realizes that exemplar two ends produce relative motion, reaches the test of exemplar endurance
Require；By in pairs plus putting extension spring and being used as elastic buffering mechanism at sliding platform two ends, under the balance of mechanical spring force,
There is reaction force to inertia force, sliding platform inertia force is balanced, reduce inertia force effect, eliminate the bad shadow of inertia force
Ring, reach sliding platform and operate steadily.
Spring Selection follows hooke theorem f=k.t, and it is spring deformation length, spring t and cunning that k is the elastic coefficient, t
Moving platform stroke is synchronous all the time equal, the direction of acting force of the spring f and in opposite direction, i.e., the motion side with slide unit of inertia force F
To contrary.By selecting suitable spring specification to meet inertia force F.By adjusting the speed-frequency and crank of buncher
The length of connecting rod, meets the parameter needed for measurement.
Compared with prior art, the utility model by sliding platform direction of motion both sides in pairs use extension spring,
With spring force come balance inertial force, inertia force effect is reduced, the harmful effect that inertia force is produced to test is eliminated, slip is reached flat
It is steady that platform is moved；Take the hollow out flat board of light weight as sliding platform simultaneously, further reduce inertia force, it is ensured that device is transported
Row is steady.This apparatus structure is simple, strong adaptability, changes quick, convenient to carry out, time saving and energy saving；Spring is adjustable, and specification is more, choosing
Type is convenient, and installs solid and reliable.
