Description

Technical Field

[0001] The utility model relates to the technical field of rubber testing, in particular to a frost removal tool for an ice grip testing machine. Background Art

[0002] Before tires are finalized, ice grip tests are required to test the grip performance of car tires on icy roads. When the LAT100 test machine conducts ice grip tests, it can test the ice grip performance of samples at different ice surface temperatures; however, the test machine can only control the surface temperature of the ice tray, and cannot control the temperature and humidity of the test environment. Therefore, frost will form on the surface of the ice tray, and as the test time increases, the degree of frost on the surface of the ice tray will gradually increase. The frost phenomenon is particularly obvious when the humidity rises in summer, which seriously affects the repeatability and accuracy of the test results.

[0003] From the perspective of equipment modification, the equipment can be transformed into a temperature and humidity controlled environmental chamber to minimize humidity, but the cost is relatively high. Moreover, the LAT100 ice grab test is a short-term test that requires frequent sample replacement. Even if the modification is carried out, there will still be fluctuations in temperature and humidity, so the modification is of little significance. Utility Model Content
