Description
Technical Field
The invention belongs to the field of tire production and manufacturing, and relates to a stability control tire, a rapid processing method, an application and a stability judging method; and (3) performing a high-temperature nitrogen-oxygen aging test under specific conditions on the control tire obtained by screening to quickly age the tire to a state with stable performance, and judging the stability of the cornering stiffness and the lateral adhesion coefficient of the control tire so as to be used for monitoring the state of a tire testing machine.
Background
The tire bench test machine typically performs sensor calibration once every 1-2 years to calibrate the equipment accuracy. The tire control method can be adopted for monitoring the daily use states of equipment such as the daily stability of the sensor in the calibration interval, the wearing condition of the test pavement and the like. The tire control method is to control tires to perform tire control tests under specific conditions on a test machine in a fixed period through a laboratory, obtain test data, extract characteristic indexes and judge the quality, so as to monitor the daily use state of test equipment. The control tire needs to ensure that the performance change is small enough in the service cycle so as to reduce the interference of the self-difference on the state index judgment of the tire testing machine. The tire aging phenomenon causes a large change in performance during the service period, which is enough to affect the equipment monitoring. Although the tire can reach a performance long-term stable state after aging under natural conditions, the tire takes years, is too long and inefficient, and is inconvenient to obtain a required control tire.
At present, the tire control method in the daily state monitoring of test equipment in the tire industry is rarely researched, and the stability problem of the control tire is not solved effectively.
For the above reasons, it is necessary to develop a fast processing method for realizing the stability of the control tire, so that the mechanical property of the control tire reaches a relatively stable state as soon as possible, and the interference of the difference of the control tire on the monitoring index value of the tire testing machine is reduced, so as to ensure that the method for controlling the state of the tire monitoring equipment is reliable and efficient.
Disclosure of Invention
In order to overcome the defect that the state of a tire testing machine is monitored by a tire control method, the invention aims to provide a rapid processing method of a stability control tire.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a method for rapid processing of a stability control tire, the method comprising the steps of: filling mixed gas of oxygen and nitrogen into the control tire, and then putting the control tire into an oven for heating, and performing constant-temperature aging; the ratio of the mixed gas of oxygen and nitrogen is 3:7-6:4, the pressure is 240-280kPa, the temperature of the oven is 50-80 ℃ and the time is 10-20 days.
Further, the invention installs the control tyre on the rim, leaks out the air in the tyre, fills the mixed gas of nitrogen and oxygen, and stands for at least 3 hours at room temperature to reach the state of inflation balance; then detecting the air pressure and the oxygen concentration, and adjusting the air pressure and the oxygen concentration to constant temperature ageing specified values.
Further, the control tire is taken out from the oven every 5-10 days in the constant temperature aging process, the tire is cooled to the room temperature, the gas in the tire is discharged, the nitrogen-oxygen mixed gas is refilled to the constant temperature aging appointed value, and the tire is put back into the oven for continuous aging.
Further, after the constant-temperature aging is finished, the control tire is taken out of the oven, the mixed gas of nitrogen and oxygen is discharged, and fresh air is filled; storing the controlled tyre in an indoor environment with constant temperature of 20-30 ℃ and humidity of 40-60%.
As a specific embodiment, the method of the present invention comprises the steps of:
1) Selecting and controlling tires according to the state monitoring requirements of the tire testing machine;
2) Mounting the control tire on a rim, discharging air in the tire, charging mixed gas of nitrogen and oxygen to 270-290kPa, and standing at room temperature for at least 3 hours to achieve an air balance state;
3) Then detecting the air pressure and the oxygen concentration, filling mixed gas of oxygen and nitrogen into the control tire, and then putting the control tire into an oven for heating, and performing constant-temperature aging; the ratio of the oxygen to the nitrogen mixed gas is 3:7-6:4, the pressure is 240-280kPa, the temperature of the oven is 50-80 ℃ and the time is 10-20 days;
4) Taking out the control tire from the oven every 5-10 days in the constant temperature aging process, waiting for the tire to cool to room temperature, discharging the gas in the tire, re-filling the nitrogen-oxygen mixed gas to a constant temperature aging appointed value, and putting the tire back into the oven for continuous aging;
5) Taking out the control tire from the oven after constant temperature aging is finished, discharging nitrogen-oxygen mixed gas, and charging fresh air to 240-260kPa; storing the controlled tyre in an indoor environment with constant temperature of 20-30 ℃ and humidity of 40-60%.
Preferably, the ratio of the oxygen gas to the nitrogen gas is 1:1, the pressure is 250kPa, the oven temperature is 65 ℃ and the time is 14 days. Of course, according to the invention, certain basic rubber materials can be generally and fixedly selected according to the control of the tread rubber of the tire, and the required oven temperature and aging time can be set according to the relation between the hardness or modulus change and the nitrogen-oxygen aging time, so as to perform constant-temperature aging.
