Nexen Tire has shared details of how it has used Artificial Intelligence (AI) and big data-driven methodology to help reduce tyre noise. The big data research for Noise, Vibration, and Harshness (NVH) was jointly conducted with Hyundai-Kia Automotive Group and Inha University in Korea. The results of the braking test performance on snow, hydroplaning, and wet surfaces showed internal and external noise generated by cars can be reduced by 1 dB (decibel) and 3 dB (decibel), respectively.
Many international manufacturers view a good EU tyre label result as a benchmark of product performance. At the end of 2018, Prinx Chengshan’s research and development centre in China began work on its ‘AA1’ project, with the aim of developing a product achieving the best label category for wet grip, rolling resistance and noise. The tyre maker reports that it’s achieved its goal.
Tyre noise can drain the pleasure out of driving and is often an issue when fitting low profile or wide tyres. Many manufacturers combat the problem, particularly when supplying OEM partners, by affixing sound-absorbing foam to the tyre’s inside. But now effective are such solutions? This is a question that Swedish motoring publication Vi Bilägare […]
Goodyear’s SoundComfort has been voted Product of the Year 2019 in a consumer research survey conducted by Nielsen in Belgium and the Netherlands. The noise reduction technology aims to address consumer and market needs as a result of the decreasing noise of car engines, especially since the arrival of electric and hybrid vehicles. With less noise coming from the engine, the noise caused by tyres is becoming more noticeable.
Homologations of Pirelli tyres equipped with the manufacturer’s Pirelli Noise Cancelling System (PNCS) technology numbered 78 by the end of 2017. One year later, the figure increased by 100 per cent, now making a total of more than 150.
Together with autonomous driving specialist ZMP Inc., Bridgestone Corporation has launched a development project to utilise automated driving technology in tyre noise tests. By removing the driver from the process, the Japanese firms aim to increase the accuracy and efficiency of this particular tyre test.
In recent years we’ve seen a number of tyre makers introduce noise reduction technologies that utilise foam insulation, with Continental, Hankook, Bridgestone, Sumitomo Rubber, Goodyear amongst those bringing their own version of the concept to market. Toyo Tire & Rubber Co. Ltd. has taken a different approach and sought instead to cut noise by modifying airflow within the tyre cavity. It calls its solution Toyo Silent Technology.
The Korean Ministry of Environment has announced that domestic and overseas tyre manufacturers will be obliged to indicate the noise level of their products from 2019. The policy announced in Korea on Monday follows the E.U. standards as well, the ministry said, and will be applied to tiyes on passenger vehicles starting in 2019, and […]
Goodyear has launched a new tyre designed to replace the much vaunted Eagle F1 GSD3, which scored top marks in almost every test going – including Auto Express, Autocar, Max Power, Evo and Which? But while the old tyre’s symmetrical tread design was key to the product’s success, Goodyear is expecting the new product to succeed exactly because it isn’t. In addition to an asymmetrical tread design, the Eagle F1 Asymmetric features an asymmetric casing construction designed to reinforce one side and squeeze more grip from the tyre. Goodyear representatives told Tyres & Accessories they were gearing up for more award success following the introduction of the ‘Active Cornergrip Technology’ into the design of its latest tyre.
