Bay Systems Limited: Proof of Concept of a wireless sensor to measure Tyre Cavity Temperatures

Bay Systems有限公司正在开发一种无线轮胎腔温度传感器的概念验证，这种传感器可以很容易地安装，足够小，可以安装在轮胎内部，并且足够坚固，可以在轮胎旋转时工作。准确的内部温度测量将提高轮胎设计的精度，因为在轮胎腔内的直接测量将不依赖于建模假设。概念验证需要设计传感器和电子设备，包装和测量方法，以便在轮胎和轮辋之间非常有限的可用空间内实现可靠的操作。这些传感器需要小巧，无线，能够承受巨大的力量和不可避免的粗暴处理，因为轮胎在测试条件下安装，拆除和驱动。对于轮胎和汽车制造商来说，创建这种传感器非常重要，因为他们需要了解现实世界条件下复杂的轮胎材料行为。这需要精确测量轮胎的物理参数，如轮胎在现实条件下旋转时的内部温度，无论是在实验室还是在道路上。一个强大的，可重复使用的传感器，易于使用，将使这种内部测量成本有效地包括在重建制度。改进车辆轮胎的设计可以对提高车辆的乘坐质量、耐久性、能耗、噪音和颗粒物排放做出关键贡献。

Bay Systems Limited are developing a proof of concept of a wireless Tyre CavityTemperature sensor which can be easily fitted, is small enough to fit inside the tyre and robustenough to work whilst the tyre rotates. Accurate internal temperature measurements willimprove tyre design accuracy since direct measurements within the tyre cavity will not bereliant on modelling assumptions.The proof of concept requires the design of sensor and electronics, packaging andmeasurement approaches to enable reliable operation in the very constrained space availablebetween tyre and rim. These sensors need to be compact, wireless and able to withstand thelarge forces and unavoidable rough handling as tyres are fitted, removed and driven in testconditions.Creating this sensor is important to tyre and vehicle manufacturers who need to understandthe complex tyre material behaviours in real world conditions. This requires accuratemeasurements of physical tyre parameters such as temperature inside the tyre as it rotatesunder realistic conditions, whether in the lab or on the road. A robust, reusable sensor that iseasy to use will enable this internal measurement to be cost effectively included in the tyredevelopment regime. Improving the design of vehicle tyres can make a critical contribution toimproving vehicle ride quality, durability, energy consumption, noise and particulate matteremissions.
