Embodiment Construction

[0053] Using the present invention to measure the cornering characteristics of 205 / 60R16 semi-steel radial tires in different regions, the following is a specific embodiment process.

[0054] 1. Select a 205 / 60R16 semi-steel radial tire as a test tire.

[0055] 2. Install the test tire on the 6J×16 rim and inflate it to an air pressure of 250kPa, then place it in the laboratory (room temperature controlled at 24±3°C) for 3 hours to achieve the temperature balance inside and outside the tire , and in preparation for preload with the tire inflated.

[0056]3. Install the inflated and parked test tires on the MTS flat-trac CT model testing machine, set the required tire pressure to 250kPa, the road speed to 60kph, the vertical load to 5000N, the roll angle to zero degrees, and the side deflection The angle was set to 0° and the run was run for 10 minutes. Then set the side slip angle to dynamic loading, from 0°→10°→-10°→0° (the side slip angle loading rate is set to 10° / s), and...

Abstract

The invention belongs to the field of lateral mechanical property testing and dynamic modeling of car tires, and particularly relates to a tire lateral deviation characteristic measurement and data processing method and device and a computer readable carrier medium. According to the invention, the slip angle measurement range is divided into a linear region, a non-linear region under the condition of small slip angle and a non-linear region under the condition of large slip angle. Through independent measurement of a linear region, the influence caused by tire tread abrasion and friction heat generation is eliminated; according to non-linear area measurement, the test temperature rise of the tire can be controlled within a reasonable range by adjusting the slip angle loading rate and cooperating with a standing cooling mode. According to the tire lateral deviation characteristic data measured based on a partition measurement mode, the influence of heat generated by friction on a linear region of the lateral deviation characteristic is eliminated, meanwhile, the real tire working state can be accurately reflected in a nonlinear region, and the quality of lateral modeling test data of a stable tire model can be improved.

Description

technical field [0001] The invention belongs to the field of lateral mechanical characteristic testing and dynamic modeling of car tires, and in particular relates to a tire lateral characteristic measurement and data processing method, device and computer-readable carrier medium. Background technique [0002] Vehicle dynamics simulation technology has become an important means of automobile research and development. From the performance target design before mule car manufacturing to the performance adjustment of the whole vehicle before pre-production, the application of dynamic simulation runs through almost every stage of automobile research and development. The tire model is a necessary input for vehicle dynamics simulation. A high-precision tire model can more realistically express the physical tire performance. Commonly used tire models include PAC2002 tire model, FTire tire model and CDTire tire model. Among them, the tire model suitable for vehicle stability simulati...
