Abstract Tire performance over soft soil is of interest for automotive and geotechnical engineers; the automotive engineers are mainly interested in tire tractive performance, and geotechnical engineers are concerned with the effects of the traffic brought by the tire to the soil. This two-part paper documents a series of tire and soil tests (Part I) and the application of their test data to the study of tire tractive performance over soft soil (characterized by drawbar pull) and to the model parameterization (Part II). Part I of this paper details the series of tests that are comprised of static tire deflection tests, static tire-soil tests, soil properties tests, and dynamic tire-soil tests, and describes the influence of tire inflation pressure or soil compaction level on the test data. The experimental approach presented herein produces parameterization and validation data that can be used in tire off-road traction dynamics modeling and terramechanics modeling.

在软土上研究轮胎牵引性能的系统测试：第一部分 - 实验数据收集

摘要 软土上的轮胎性能是汽车和岩土工程师感兴趣的。汽车工程师主要对轮胎的牵引性能感兴趣，而岩土工程师则关心轮胎对土壤带来的交通影响。这篇由两部分组成的论文记录了一系列轮胎和土壤测试（第一部分）及其测试数据在软土地上轮胎牵引性能研究（以牵引杆拉力为特征）和模型参数化（第二部​​分）中的应用。本文的第一部分详细介绍了由静态轮胎挠度测试、静态轮胎土壤测试、土壤特性测试和动态轮胎土壤测试组成的系列测试，并描述了轮胎充气压力或土壤压实水平对轮胎的影响。测试数据。
