【摘要】：随着科学技术的不断进步以及国民经济的快速发展,车辆的使用已经遍及到军事、农业、林业等各个领域,为了提供一个舒适安全的驾驶环境,车辆的地面安全可通过性能更是越来越多的受到人们的关注。人们希望能有一系列的安全评价标准或者是评价系统来指导他们快速无伤害的通过各种平坦或者是非平坦路面。为了满足大众需求,车辆的地面可通过性研究便成为一个国内外研究学者普遍研究的热点问题。研究车辆的地面可通过性不仅能够帮助我们提前感知车辆对未知路面的可通过性能,而且还可以帮助我们根据已知的地面参数特性来选择最佳的行驶方案。本论文从研究车辆的力学性能以及其他车辆行驶状态参数两方面入手设计与车辆地面通过性测试系统相应的软硬件模块来获取测试数据并对这些数据进行采集、显示、存储以及建模分析。系统硬件设计主要包括各个模块所需传感器的设计及选型、数据的发射及接收。系统软件设计主要包括数据的采集与控制以及数据的去噪、显示和存储等。为了更精确的表达各系统参数之间的内在规律性,本文决定对采集到的与通过性有关的系统参数进行数学建模来分析这些参数与通过性的内在联系。为了验证车辆地面通过性测试系统的可靠性,本文对该测试系统进行了实车试验,并将通过试验得到的与通过性相关的系统参数使用MATLAB软件进行数学建模分析,经过试验及分析,进一步证明该车辆地面通过性测试系统的可行性。
[Abstract]:With the continuous progress of science and technology and the rapid development of the national economy, the use of vehicles has spread throughout the military, agriculture, forestry and other fields, in order to provide a comfortable and safe driving environment, More and more attention has been paid to the safety performance of vehicles. People hope to have a series of safety evaluation criteria or evaluation systems to guide them to quickly and harmlessly pass through a variety of flat or uneven roads. In order to meet the needs of the public, the research on the ground transmissivity of vehicles has become a hot topic for domestic and foreign researchers. The study of the transmissivity of vehicles on the ground can not only help us to perceive the transmissivity of vehicles to unknown pavement ahead of time, but also help us to select the best driving scheme according to the characteristics of known ground parameters. In this paper, the mechanical properties of the vehicle and other vehicle driving state parameters are studied to design the software and hardware modules corresponding to the vehicle ground pass test system to obtain the test data and to collect and display the data. Storage and modeling analysis. The hardware design of the system mainly includes the design and selection of the sensors needed by each module, the transmission and reception of data. The system software design includes data acquisition and control, data denoising, display and storage. In order to more accurately express the inherent regularity between the system parameters, this paper decides to analyze the intrinsic relationship between these parameters and the transmissivity by mathematical modeling of the collected system parameters related to transmissivity. In order to verify the reliability of the vehicle ground pass test system, a real vehicle test is carried out in this paper, and the system parameters related to the passing property obtained through the test are modeled and analyzed by MATLAB software. Through the test and analysis, the feasibility of the vehicle ground pass test system is further proved.
