Simulation environment for sensor-enhanced tires - SENSE

自动驾驶汽车和智能汽车在德国和中国都受到越来越多的关注，并形成了一种新的移动技术，这将改变行业生态系统和人类生活中的交通方式。轮胎是汽车和车辆的关键部件，通过建立汽车和道路之间的联系（车辆-轮胎-道路系统）。此外，智能轮胎在现代智能交通系统中发挥着关键作用，在该系统中，车辆-轮胎-道路系统将被监测和主动驱动。从智能轮胎的应用来看，由于配备传感器的轮胎（轮胎动力学）的真实的时间监测，而且还可能提高车辆底盘控制的性能，因此预期会带来好处。然而，智能轮胎的制造过程并不简单，因此需要对潜在的传感器位置和制造过程进行深入研究。中国是一个不断增长的轮胎制造市场。德国传统上拥有与提高质量和环境可持续性相结合的专业知识。因此，中国清华大学汽车工程系与德国德累斯顿工业大学结构分析研究所之间的联合研究方法似乎很有前途，并结合了双方的专业知识。在联合项目中，智能轮胎传感器系统得到了解决。调查的对象是智能轮胎的设计和仿真，结合现有的功能元件（轮胎：负载传输，机械部分;传感器：监测设备）。其旨在提供传感器获得的量与待监测的量（力、力矩、轮胎速度）之间的数学关系。为了识别轮胎设计中的潜在传感器位置，还解决了具有或不具有传感器的轮胎的制造。计划通过有限元方法从未固化到最终固化的轮胎进行热机械轮胎模制模拟，以揭示所制造的轮胎的初始状态（例如，由于制造过程中的几何形状变化和热作用而导致的帘线中的预应力），并评估制造期间放置在轮胎内的传感器装置的最终位置。进一步的研究课题将包括智能轮胎性能的设计和仿真、传感器的设计和选择、系统集成、传感器的电源及其与控制单元的通信。这里的问题是关于集成传感器的潜在位置和由此产生的耐用性问题。主要目的是提供一个模拟环境的传感器增强轮胎。

Autonomous cars and smart vehicles gain increasing attention across both Germany and China and form a new mobility technology, which will change the industry ecosystem and the way of transport in human life. Tires are a key part of cars and vehicles by establishing the link between car and road (vehicle-tire-road system). Furthermore, smart tires play a key role in the modern smart transportation system in which the vehicle-tire-road system will be monitored and actively actuated. From the application of smart tires, benefits are expected due to real time monitoring by sensor-equipped tires (tire dynamics), but also from the potential to enhance the performance of the vehicle chassis control. However, the manufacturing process of smart tires is not trivial and, in consequence, requires a profound study of potential sensor positions and manufacturing processes taking place.China is a growing market for tire manufacturing. Germany traditionally hosts expert knowledge in combination with enhancing quality and environmental sustainability. Therefore, a joint research approach between the Department of Automotive Engineering at the Tsinghua University in China and the Institute for Structural Analysis at the Technische Universität Dresden in Germany seems promising and combines pronounced expert knowledge from both sides.Within the joint project, the smart tire-sensor system is addressed. The object of investigation is the design and simulation of a smart tire by combining existing functional elements (tire: load transmission, mechanical part; sensor: monitoring equipment). It is intended to provide a mathematical relationship between the quantities obtained by the sensors and the quantities to be monitored (forces, moments, tire velocities). To identify potential sensor locations in the tire design, the manufacturing of tires with or without sensors is addressed as well. A thermo-mechanical tire moulding simulation by the finite element method from the uncured to the final cured tire is planned to reveal the initial state of the manufactured tire (e.g. pre-stress in cords due to geometry changes and action of heat during manufacturing process) and to evaluate the final location of sensor devices placed within the tire during manufacturing. Further research topics will cover the design and simulation of the smart tire performance, the sensor design and selection, the system integration, the power supply for the sensor and its communication with control units. Here the question is about the potential location of integrated sensors and resulting durability issues. The main objective is to provide a simulation environment for sensor-enhanced tires.
