FPS Abrasion Tester AB-2012

OUTLINE

AB-2012 FPS Abrasion Tester can perform
tests by controlling tangential force
between the test piece and the abrasive whee
in addition to the conventionalcontrol of slip
ratio, aiming more correlation to the real tires.

A Lambourn abrasion tester or conventional FPS tester, which is used for abrasion tests of high polymer material for such products like tire and belt, controls slip ratio or speed difference between test piece and abrasive wheel while doing an abrasion test. AB-2012 FPS Abrasion Tester can perform tests by controlling tangential force between the test piece and the abrasive wheel in addition to the conventional control of slip ratio, aiming more correlation to the real tires. It was necessary to repeat tests with different conditions in order to evaluate abrasion vs friction energy, which is deemed to have more correlation to the real tire. The FPS abrasion tester enables to reproduce conditions of real tire more precisely by directly controlling the friction force.

TEST ITEMS

Slip ratio regulation test
Friction force regulation test

FEATURES

Friction force regulation tests which were not available with conventional abrasion testers.

Real-time measurement of test piece diameter for feed-back of the circumferential speed.
Control of abrasive wheel temperature without using a slip ring. (optional)
Simplified test piece transport system using the swing arm.
Improved test piece clamping system with a ratchet.
Use of the accurately controlled talc feeding system for adhesion preventing. (Japan patent no. 4559617)
High repeatability of test conditions with Safety Walk used as abrasive.
Fully automatic tests of 64 (10-mm thick) or 32 (20-mm thick) test pieces.
Two brushes clean the surface of the abrasive wheel to keep the conditions constant.
Friction energy analysis available with the exclusive software.

APPLICATIONS

Abrasion tests of rubber materials for tire, belt, roller, etc.

ISO and JIS describes abrasion testers for rubber. However, difference of specimen shapes, abrasives and methods may give different results because of the different wear mode. An optimum tester must be selected for the final product of the material and its usage conditions. The FPS abrasion tester is specially designed to get material abrasion result best correlated to that of automobile tires.

Transportation System

The hand picks up a specimen on the turret and
set it in the test section as shown.
After a test is complete, it will send back
the specimen to the turret and pick up
the next one for testing.
