How can you optimize tire design to reduce vehicle noise and vibration?

由人工智能和领英社区提供技术支持

Vehicle noise and vibration are common issues that affect the comfort and safety of drivers and passengers. One of the main sources of these problems is the tire, which interacts with the road surface and transmits forces and sounds to the vehicle body. How can you optimize tire design to reduce vehicle noise and vibration? In this article, you will learn about some of the factors that influence tire performance and some of the methods that engineers use to improve it.

1 Tire structure

The tire is composed of several layers of materials, such as rubber, steel, and nylon, that give it strength, flexibility, and durability. The tire structure affects how it deforms and recovers when it rolls over the road, which in turn affects the noise and vibration it generates. For example, a stiffer tire may produce less rolling resistance and better fuel efficiency, but also more noise and harshness. A softer tire may provide more comfort and grip, but also more heat and wear. Engineers have to balance these trade-offs and find the optimal tire structure for different driving conditions and vehicle types.

2 Tire tread

The tire tread is the part of the tire that contacts the road and provides traction and handling. The tread pattern, shape, and depth influence the noise and vibration that the tire produces. For example, a smooth tread may reduce noise, but also reduce grip and increase hydroplaning risk. A grooved tread may improve drainage and stability, but also create more air pumping and friction noise. Engineers have to design the tread to minimize noise and vibration while maintaining adequate performance and safety.

Pour réduire le bruit de roulement et les vibrations , certains constructeurs utilisent une bande de mousse collée à l’intérieur de la bande de roulement.

3 Tire pressure

The tire pressure is the amount of air inside the tire that supports the vehicle load and maintains the tire shape. The tire pressure affects the noise and vibration that the tire transmits to the vehicle. For example, a low tire pressure may reduce noise and increase comfort, but also increase rolling resistance and tire wear. A high tire pressure may improve fuel efficiency and handling, but also increase noise and harshness. Engineers have to recommend the optimal tire pressure for different vehicle models and driving scenarios.

4 Tire modeling

The tire modeling is the process of creating mathematical and computational representations of the tire behavior and performance. The tire modeling helps engineers to understand and predict how the tire interacts with the road and the vehicle, and how it affects the noise and vibration levels. For example, a tire model can simulate the dynamic response of the tire to different road surfaces, speeds, loads, and temperatures, and calculate the noise and vibration spectra and modes. Engineers can use tire models to evaluate and compare different tire designs and optimize them for noise and vibration reduction.

It just depends on the type of tire you’re running. You could have a drag or race car and you don’t give a stink. A road car depends on the rim and tire size. I think you’re putting far too much thought into tire design. That’s been on going for 100+ years. I think with the EV vehicles that may be a concern to some people. Don’t always trust your models or analysis. I’d rather have my tires grip well and have long life. I don’t care about the sound.

5 Tire testing

The tire testing is the process of measuring and validating the tire performance and quality. The tire testing involves both laboratory and field experiments that expose the tire to various conditions and stimuli. The tire testing helps engineers to verify and improve the tire design and identify and solve any problems or defects. For example, a tire test can measure the noise and vibration levels of the tire under different road textures, frequencies, amplitudes, and directions, and compare them with the standards and specifications. Engineers can use tire tests to refine and optimize the tire design and ensure its reliability and durability.

6 Tire optimization

The tire optimization is the process of finding the best tire design that meets the desired objectives and constraints. The tire optimization involves both analytical and numerical methods that search for the optimal solutions among a large number of possible alternatives. The tire optimization helps engineers to achieve the highest performance and quality of the tire while reducing the noise and vibration. For example, a tire optimization can use optimization algorithms and criteria to find the optimal tire structure, tread, and pressure that minimize the noise and vibration levels while maximizing the fuel efficiency, comfort, and safety. Engineers can use tire optimization to create and implement the best tire design for different applications and markets.
