Description
Technical field
The utility model is related to road engineering studying technological domain, more particularly to a kind of tire and road surface contact
Test device and measuring system.
Background technology
Tyre contact pressure is always Tire production industry and traffic department focus of interest.Initial stage, traffic loading
It is relatively light, tire size and the reason such as material is relatively soft in addition, tire-contact area is in approximate circle, pavement structure mechanics
It is simplified mathematical model during analysis, tire ground connection load is usually reduced to uniform equivalent circle load, and adopted extensively
With.
With the progress of entire society, either Tire production industry or Pavement Structure Design person notice heavy duty
Under traffic, large scale tire, wheel load high (more than 0.7MPa), the improvement of the improvement even tire material of tyre tread are all led
Tire-contact area area, pressure is caused all to be clearly distinguishable from the understanding of early stage, therefore contact interface area and pressure distribution is effective
Detection technique just seems very crucial.
In automobile tire manufacturing, it usually needs carry out ground contact pressure distribution experiment to automobile tire to evaluate tire
Performance and endurance quality, conventional loading equipemtn has tyre last drum tester and static loading testing machine, main

The indoor measurement apparatus of touch pressure, reduce the empirical risk of engineering site and reduce unnecessary environmental factor and do to greatest extent
Disturb, improve test efficiency and certainty of measurement.
Existing tyre contact pressure method of testing mainly has pressure plare method, pressure sensor method, pressure-sensitive embrane method and light to inhale
Receipts method etc., the method for current more common also comparative maturity is resistance strain type pressure sensor method.Resistance-strain type pressure is passed
Sensor method of testing is mainly multi-point sampler method, and certainty of measurement is relatively low, due to the distribution of sensor dot matrix, between existing between sensor
Gap so that real contact area during test with tire is reduced, and the measurement result for obtaining can be bigger than normal, further, since resistance-strain
Formula pressure sensor is not amenable to HTHP, and bituminous concrete shaping need to be by HTHP, therefore must be in pitch coagulation
The position of good sensor is reserved before soil casting, after sensor is inserted again after concrete formation, will necessarily road pavement cause brokenly
It is bad, influence the true measurement on road surface.
In sum, how a kind of measurement system of the contact that can accurately, truly measure tire and road surface is provided
System is the technical problem of those skilled in the art's urgent need to resolve.
