Abstract

Abstract: Airless tires are the best innovation for military tactical vehicles in carrying out the Army's main tasks for military tactical even peace support operations and war military operations. However, in its development there are still imperfections in the results, its fabrications in the adhesion between polyurethane and natural rubber. Therefore, the researchers aimed to develop the adhesion between polyurethane and natural rubber. In this research, a quantitative experimental method was used, namely by varying the hardness of natural rubber and polyurethane to determine the right hardness for airless tires for maximum adhesion. The problem that occurs is that the adhesive glue with the tire tread is problematic, resulting in a tire tread condition without air being released. In carrying out the research, a function test was carried out with a planned weight of 4,500 Kg. Based on the results of the tests that carried out, the correct result was obtained, namely the elongation at break of the most appropriate type of polyurethane L100, which was 9.287 MPa. In order to achieve the goal, namely the appropriate level of elasticity between polyurethane and natural rubber so as to be able to glue the spokes and tire treads, in the end the wheel rotation will rotate according to the desired elasticity.

聚氨酯和天然橡胶的硬度对无气轮胎附着力的影响

摘要:无气轮胎是军事战术车辆在遂行陆军军事战术乃至和平保障行动、战争军事行动等主要任务时的最佳创新。然而，在其发展的结果中还存在着不完善之处，其制造工艺在聚氨酯与天然橡胶之间的粘附性方面。因此，研究人员的目标是开发聚氨酯和天然橡胶之间的附着力。本研究采用定量实验的方法，即通过改变天然橡胶和聚氨酯的硬度来确定适合无气轮胎的硬度，以获得最大的附着力。出现的问题是轮胎胎面胶有问题，导致轮胎胎面状况不释放空气。在进行研究时，进行了计划重量为4,500 Kg的功能测试。根据所进行的试验结果，得到了正确的结果，即最合适型号的聚氨酯L100的断裂伸长率为9.287 MPa。为了达到目的，即聚氨酯和天然橡胶之间有适当的弹性水平，从而能够粘住辐条和轮胎胎面，最后车轮会根据期望的弹性旋转。
