重型货车轮胎接地压力分布实测

Measuring Tire Ground Pressure Distribution of Heavy Vehicle

目前路面力学大部分相关研究都把轮胎接地压力简化为圆形均匀分布,这与实际有很大的差别.轮胎接地压力分布随着轮胎的胎压、负荷、花纹甚至使用年限的不同而有很大不同,且呈明显的非均匀分布.为此利用自主开发的轮胎接地压力测试仪,进行了重型货车不同花纹轮胎在不同轮胎胎压和不同负荷作用下的接地压力分布测量.

Currently, it is very different from actual conditions that in the most research of pavement mechanics,the mode of tire ground pressure is simplified as circular and uniform distribution. In fact the tire ground pressure distribution is not-uniform. Actually it varies with the variety of loads, tire air pressures, tread patterns and the age of tires. In this paper, a measuring device has been developed and used to measure the tire ground pressure distribution of light vehicles of different tread patterns with different tire air pressures and different tire loads.
