Abstract

Japan has many active volcanoes, and a large eruption can cause ash fall over a wide area. The accumulation of volcanic ash on paved roads affects the driving of vehicles. Therefore, we collected data by driving over volcanic ash accumulated on paved surface with a vehicle equipped with devices that can measure the force applied to the running tires. Vehicle driving tests were conducted at constant speed, rapid acceleration, and rapid deceleration. Data were collected on flat straight roads as well as on roads with grades and curves. In addition to longitudinal, lateral, and vertical tire forces, camber angle, rotation speed, and ground speed were measured. This paper discusses the effects of volcanic ash covering paved roads on driving by processing the tire data obtained. The relationship between the sideslip angle and side force can be obtained by processing turning driving data, and these effects were modeled using a neural network and Gaussian process that can consider multiple variables such as tire sideslip angle, camber angle, and vertical force.

在铺有火山灰的沥青路面上行驶的轮胎特性分析
日本有许多活火山,大面积喷发会导致火山灰大面积降落。火山灰堆积在铺设好的道路上会影响车辆的行驶。因此,我们使用装有可测量行驶轮胎受力装置的车辆,在铺设路面上堆积的火山灰上行驶,收集数据。车辆驾驶测试在匀速、急加速和急减速的情况下进行。数据是在平坦的直线道路以及有坡度和弯道的道路上收集的。除了纵向、横向和垂直轮胎力之外,还测量了外倾角、旋转速度和地面速度。本文通过处理获得的轮胎数据,讨论了火山灰覆盖铺设道路对驾驶的影响。通过处理转弯驾驶数据,可获得侧倾角和侧向力之间的关系,并使用神经网络和高斯过程对这些影响进行建模,神经网络和高斯过程可考虑轮胎侧倾角、外倾角和垂直力等多个变量。

期刊介绍: The Journal of Terramechanics is primarily devoted to scientific articles concerned with research, design, and equipment utilization in the field of terramechanics. The Journal of Terramechanics is the leading international journal serving the multidisciplinary global off-road vehicle and soil working machinery industries, and related user community, governmental agencies and universities. The Journal of Terramechanics provides a forum for those involved in research, development, design, innovation, testing, application and utilization of off-road vehicles and soil working machinery, and their sub-systems and components. The Journal presents a cross-section of technical papers, reviews, comments and discussions, and serves as a medium for recording recent progress in the field.
