摘要针对非公路（OTR）和重型（HD）轮胎，开发了一种能够以合理的速度和准确性预测其使用性能的实验室切削和切屑测试方法。它使快速和低成本地调查许多复合因素成为可能。可以对直径5.08厘米，厚度1.27厘米，重约25克的圆盘形状的样品进行测试。测试样品可以从混合橡胶化合物中固化，测试用于评估复合变量或作为质量控制的工具。也可以从硫化OTR轮胎的凸耳中取出样品。切割和剥落已经被定义，并且对被认为与切割和剥落有关的因素进行了分析，因此可以制定必要的测试标准。实验装置简单、操作方便、快速、重复性好。测试结果对五种OTR化合物按现场经验排序。测试单一橡胶化合物的再现性。
Abstract A laboratory cutting and chipping test for off-the-road, (OTR) and heavy duty, (HD) tires has been developed that predicts service performance with reasonable speed and accuracy. It makes possible the investigation of many compounding factors quickly and inexpensively. A test can be made on a sample in the shape of a disc 5.08 cm diameter by 1.27 cm thickness weighing about 25 g. Test samples can be cured from the mixed rubber compound and the test used for evaluation of either compounding variables or as a tool for quality control. Samples may also be removed from the lugs of vulcanized OTR tires. Cutting and chipping has been defined, and an analysis of the factors thought to be involved in cutting and chipping has been attempted so the necessary criteria for a test could be developed. The resulting apparatus is simple, easily operated, and gives a quick and reproducible test. The test results rate five OTR compounds in order of field experience. Test reproducibility on a single rubber compound...
