Sumitomo Rubber has developed a new method for predicting noise generated by the mutual vibration between tires and vehicles. To develop this method, the company used a tire rolling simulation that assumes a tire in motion. By applying this method, both the tire manufacturer and the vehicle manufacturer can improve the quietness performance. Road noise, which is generated when road...
The Japan Automobile Tyre Manufacturers Association (JATMA) has established a voluntary industry standard for the testing and labeling of low-noise tires. This comes as part of JATMA’s efforts to promote the use of tires that minimize external noise, and will form the basis of a new labeling system set to begin operation in January 2023. JATMA hopes here to help...
The Japan Automobile Tyre Manufacturers Association (JATMA) has established a voluntary industry standard for the testing and labeling of low-noise tires. Part of JATMA’s efforts to promote the use of tires that minimize external noise, the labeling system for the new operational standard for test methods and labeling methods for low exterior noise tires is set to begin operation in...
Bridgestone Corp. (TYO:5108) recently announced that it has started a development project targeting the use of driverless vehicles in tire noise tests. Such tests are one of several types conducted using vehicles. By implementing tire noise tests that deploy a self-driving vehicle rather than rely on human skills and know-how, Bridgestone aims to improve the accuracy and efficiency of its...
