Drum Abrasion Test Panel for Studded Tire Wear Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining road surface abrasion caused by studded tires are time-consuming and expensive, and are limited by temperature and humidity conditions, leading to inaccurate measurements due to soft asphalt or inability to conduct tests year-round.
Innovation Solution
A drum test method where a conventional asphalt covering is applied to the inner surface, interrupted at one point with a locally positioned covering panel made of rock or gravel embedded in a matrix, which is weighed before and after a short test run, allowing for quick and controlled abrasion testing independent of external conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If local test surfaces are used on road surface with multiple rollovers, then abrasion measurement is achieved, but test duration and cost increase significantly
Solution Approach 1:
The test surface is segmented into a modular test plate that can be independently removed and replaced. This allows the test to be conducted on a single reusable plate rather than requiring multiple sequential tests on different road surface sections, dramatically reducing test duration while maintaining measurement precision through controlled abrasion conditions.
Solution Approach 2:
A standardized test plate serves as an intermediary between the tire and the road surface. This mediator provides a controlled, repeatable test surface that can be precisely measured before and after testing, enabling accurate abrasion measurement without requiring multiple rollovers on actual road surfaces.
2Measurement precision
If conventional road surface testing is conducted, then abrasion data is obtained, but testing is limited to specific temperature ranges (0°C to 15°C)
Solution Approach 1:
The test plate is pre-weighted and prepared before installation on the drum. This preliminary preparation allows the same plate to be used across different temperature conditions without requiring re calibration or adjustment, enabling versatile testing from -30°C to +50°C while maintaining measurement precision through consistent baseline measurements.
Solution Approach 2:
The testing system accommodates parameter changes in temperature by using a controlled environment chamber and selecting appropriate tire compounds for different temperature ranges. The test plate itself remains unchanged, providing consistent measurement reference across the expanded temperature range of -30°C to +50°C.
3Measurement precision
If complete drum lining with test covering is used, then comprehensive abrasion assessment is achieved, but device complexity and installation time increase
Solution Approach 1:
The essential test function is extracted from the complex complete drum lining and concentrated into a single removable test plate. This plate is installed in a specific position on the drum where it receives sufficient tire contact during rotation, providing comprehensive abrasion assessment without requiring the entire drum to be lined with test material.
Solution Approach 2:
Instead of uniformly lining the entire drum with test covering, the test plate is strategically positioned at a specific location on the drum inner surface. This localized approach provides sufficient tire contact for comprehensive abrasion assessment while dramatically reducing device complexity and installation requirements compared to complete drum lining.
4Adaptability or versatility
If multiple interchangeable cassettes are used for different road coverings, then test versatility is improved, but device complexity and cost increase
Solution Approach 1:
The test plate is designed with universal applicability through standardized mounting interfaces and the option to attach different tire compounds to the same plate. This multi-functional design allows testing of various road covering types and temperature conditions using a single plate rather than requiring multiple specialized cassettes, reducing device complexity while maintaining versatility.

AI summary
The abrasion determining method involves locally introducing a road surface (6) to be tested on an inner surface (8) of a drum (1) as a cover plate or cover panels in a removable manner, where the road surface is weighed before and after test run. The test run is carried out in an air-conditioned room, where the covering panels are used at one point of the inner surface of the drum. The inner surface of the drum is overlaid with bitumen. The slip angle or the overturn of a studded tire (5) is selectable and adjustable. An independent claim is included for a device for determining abrasion of a road surface using studded tire in a test run by over traveling the road surface to be tested.
