子午线轮胎二次法成型过程仿真

为实现轮胎成型过程的可视化,利用ABAQUS软件模拟了12.00R20载重子午线轮胎的二次法成型过程。轮胎成型过程主要分为帘布筒部件贴合、一段鼓部件贴合、带束鼓部件贴合、生胎成型和硫化机内定型等5个工序。生胎成型过程采用轴对称模型模拟,运用ABAQUS/Standard隐式求解器求解;机内定型过程采用三维模型模拟,运用ABAQUS/Explicit显示求解器求解。将仿真轮胎和实际生产轮胎的材料分布图进行对比,结果表明,二者的材料分布具有良好的一致性。在此基础上,分析了机内定型过程中带束层帘线的帘线力分布和帘线角度变化。

New Method for Monitoring Tire Pressure of Cars Based on the Tire Radial Deformation

Monitoring tire pressure of cars and signaling abnormal conditions is an important means to prevent deadly accidents. Large achievements have been gained, especially in direct tire pressure monitoring system(TPMS). But there has been rarely research on indirect TPMS in the world. In China, the research on indirect TPMS is almost lacking. The international research on the indirect monitoring tire pressure method is mainly based on measuring and comparing the rotating speed of wheels. But it is very difficult to measure wheel rotating speed accurately because of the influence of many random factors. In this paper, the authors propose a new method in which the tire pressure can be monitored indirectly. This method can be used for tire calibration, wheel speed frequency standardization, wheel speed frequency comparison, and abnormal tire pressure determination. The pulse frequencies from wheel speed sensors of ABS are used to indicate tire deformation. Because the frequency has a relationship with tire deformation, the tire deformation reflects the tire pressure. Small sample statistics is used in the new method to increase the accuracy, and the experimental samples using the principle of the new method have been made and tested. The result of vehicle tests on road demonstrates that the method is efficient and accurate to monitor tire pressure. The research has positive potential for developing products.
