Tyre treads help in road grip and avoid accidents. Treat wear evaluation is the test to determine the effect on tyre treads due to long-running on different types of road conditions. The test includes real-life conditions to stimulate accurate tread wear. By creating the right conditions, the test provides results for city and highway driving treat wear.
Original equipment manufacturer validation is among the most important tests to be performed on tyres. OEM design validation includes competitive benchmarking, ice traction, and many others. The motive of this testing is to analyse the overall design quality of the tyre from the original manufacturer. Such tests are performed on all types of vehicle tyres.
Accelerated ageing is the method performed on the tyre to identify long term usage effects in a shorter time. Different factors and conditions are applied to the tyre to replicate the effects of daily usage on the tyre. The tyre undergoes chemical as well as mechanical ageing. The duration of the accelerated ageing tests depends on the type of vehicle including passenger car, trucks, and two-wheelers.
Tyre failure can occur due to poor manufacturing. Failure analysis and forensics perform several checks on the tyre development cycle to identify the true performance of the tyre. As tyre failure is among the last things that can happen to the tyre, it aids in finding the right tire forensics. Raw material specifications, tyre structural analyses, aircraft tyre analyses are among the factors that will be considered in this test.
Tyre burst testing is conducted to understand the shelf life as well as the durability of the tyre. This test is performed with the help of a hydraulic. The right pressure value is applied to the tyre through the hydraulic pump to perform the burst test. The same test is performed on all the different types of tyres but with different hydraulic pressure.
A footprint is a way how a tyre reacts when it comes to contact with the road. Footprint test helps in finding the reasons for tyre wear and how to reduce it. Ink measurements, multi-axis measurements of footprint stress, optical contact pressure measurement, and shape and void ratio are among some of the tests performed to achieve the goal. The tyre is rolled on several pins that determine the pressure and frictional energy created when the tyre contacts the road.
Understanding the performance of competitive products can help in finding significant details of your products. Competitive benchmarking is all about performing independent performance and material analysis on competitive products. The test includes a comparison of inter-company products, new and used products, and performance of products under several conditions. This test is pivotal to draw a comparison with the competitive products.
Dynamic models aid in finding the way how the vehicle responds to the road under different conditions and scenarios. With the right tyre model, the engineers can attain the right data required. However, creating a tyre model requires a lot of accurate measurements including stiffness, force, material properties, and transient response. The acquired data along with the measurements helps in getting the right results.
Tyres play a significant role in steering and controlling the vehicle. Force and moment data help in understanding several factors that help in vehicle control including handling, steering, and stopping distance. The test includes motions and stresses in tyre footprint lateral spring rates, force development and many others. It helps in collecting necessary data including slip ratio, rolling radius, camber, loaded radius, tyre treat temperature, and slip angle.
Treads are the most important parts of the tyre. Laser treat profilometry is the process to collect data that will help the manufacturer in designing the most effective tyre treads. The information helps in finding tread wear measurements, and tread loss. Not only that, but the data collected offers qualitative data of irregular tread wear pattern to create a treat profile that helps in better tyre design.
Vehicles tend to lose road grip while driving on snow. Snow and ice traction is the test to find out the snow grip performance of the tyre. The tyre undergoes several harsh snow and ice conditions to evaluate the necessary data. Depending on the tyre, the surface is customized to obtain accurate results so that they can be eligible for comparison.
Different people drive differently and all of them will leave different damage to the tyre. Subjective ride and handling are putting the tyre under different driving ways and design the model accordingly. The subject evaluation provides the right data for different types of tyres and offers the right opinion.
