Embodiment
The technical solution of the present invention will be further described below with reference to the accompanying drawings.
As shown in Fig. 1 ~ Fig. 4, novel tire Constrained mode test device of the invention includes stand 1, jack 2, rigidity Rope 3, force snesor 4 and acceleration transducer 5.
Stand 1 is used for the tire 100 for placing test, and stand 1 includes support 11 and is fixedly installed on the top of support 11 Work top 12.
Jack 2 is used to apply load to tire 100, and jack 2 is provided with handle 21, can be to wheel by operating handle 21 Tire 100 applies load.Rigidity rope 3 is used to fix tire 100, and the load that jack 2 applies is delivered into wheel from rigidity rope 3 On tire 100, and the direction of load born of tire 100 and the bearing of trend of the central axis of tire 100 are perpendicular.
Specifically, the center of tire 100 has axis hole 101, rigidity rope 3 is consolidated through its both ends after the axis hole 101 tension It is scheduled on jack 2, so, so that it may the fixation of tire 100 is realized by rigidity rope 3, will not on rigidity rope 3 in the state Pretightning force is produced, jack 2 is in minimum stroke opening position.When operating the handle 21 of jack 2, jack 2 will be made Stroke increase, and make the tensioning of rigidity rope 3, so as to apply pressure to tire 100.
Jack 2 is fixed on work top 12.In the present embodiment, jack 2 is located at the lower section of work top 12, and it is pushed up Portion is fixedly installed on work top 12, and its bottom is fixedly connected with rigidity rope 3.
Force snesor 4 is used to test stressing conditions of the tire 100 after jack 2 applies load, and in the present embodiment, power passes Sensor 4 is fixedly installed on work top 12, and positioned at the top of work top 12, the novel tire Constrained mode test device Also include pallet 6, force snesor 4 is supported on the lower section of pallet 6, and tire 100 is arranged on pallet 6.
In the present embodiment, force snesor 4 is provided with four, and four force snesors 4 are located at four angles of pallet 6 respectively, and four The summation of the individual measured forces of sensor 4 is the size for the power that the tire 100 is born.
The novel tire Constrained mode test device also includes the display for being used for the size for the power that display of tyre 100 is born Device 7, display 7 are fixedly installed on work top 12.
The neck 61 being engaged with tire 100 is provided with the middle part of pallet 6, tire 100 is fastened in the neck 61, so It can prevent rigidity rope 3 from occurring the phenomenon of the lateral deviation of tire 100 in cinching process.
A through hole is respectively equipped with the work top 12 of the both sides of tire 100, the through hole is used to wear rigidity rope 3, The through hole can also position to rigidity rope 3 simultaneously.
Acceleration transducer 5 is used to testing the mode signals of tire vibration, and in the present embodiment, acceleration transducer 5 uses Three-dimensional acceleration transducer, the three-dimensional acceleration transducer be provided with it is multiple, tire 100 includes wheel hub and tyre bead, and multiple three-dimensionals add Velocity sensor is separately positioned on the outer surface of wheel hub, tyre bead.When the size and tire 100 of the power that tire 100 is born are real Border using when the power size born it is identical when, hammered into shape using power and tap the specified location of tire 100 and can pass through acceleration transducer 5 Obtain the Mode Shape of tire 100.
The detailed process of Mode Shape using novel tire Constrained mode test device test tire is:
(1)Force snesor 4 is arranged on work top 12, pallet 6 is placed on force snesor 4, is then set the card of tire 100 In the neck 61 of pallet 6, the top of jack 2 is fixed on to the lower section of work top 12, rigidity rope 3 is passed through into tire 100 Axis hole after be fixed on the bottom of jack 2, now rigidity rope 3 in the state being tightened up but not produces pretightning force, and thousand Jin top 2 is in minimum stroke opening position;
(2)The handle 21 of jack 2 is operated, rigidity restricts 3 pretensions so as to have a downward pulling force, force snesor 4 to tire 100 Monitor the value of thrust and shown by display 7, ongoing operation handle 21 loads to tire 100, until tire 100 is held The size for the pulling force received is equal with real vehicle state;
(3)Jack 2 keeps final stress state, after arranging acceleration transducer 5 on the outer surface of wheel hub and tyre bead, makes Firmly hammer taps any given position of tire 100, and the Mode Shape of tire 100 can be obtained by acceleration transducer 5.
The novel tire Constrained mode test device can accurately simulate tire 100 under real vehicle state institute's stress it is big It is small, it is ensured that the mode accuracy of the tire 100 under test restrained condition, and solve and limited and can not be surveyed on real vehicle by space The problem of trying the mode of tire 100, can match with vehicle for the exploitation of the tire 100 of early stage and provide important evidence.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art's energy Solution present disclosure much of that is simultaneously carried out, and it is not intended to limit the scope of the present invention, all according to spirit of the invention The equivalent change or modification that essence is made, it should all cover within the scope of the present invention.
