摘要

摘要: 为保证滚动阻力测试数据的精度,需对影响设备测试性能的关键因素进行评估预测.基于检测设备的测试原理,建立了轮胎滚动阻力的数值仿真模型,通过对采集的传感器输出物理量进行算法处理,模拟多工况下滚动阻力的测试特性.改变转鼓和轮轴中心线的相对基准位置,在对测试数据差异性分析的基础上,采用一次正交回归算法对采集的数据进行误差修正.与实验室的实测数据进行对比验证,趋势性试验表明该测试模型能够正确反映滚动阻力与控制条件之间的响应关系,表明该测试模型具有较高的可靠性;重复性试验表明滚动阻力修正模型能够减小设备的系统误差,提高现有设备的测试精度.仿真结果为相关设备的研发提供了实践依据.

Abstract: To ensure test data precision for rolling resistance, the key factors affecting equipment performance were assessed and predicted. Based on the equipment measuring principle, numerical simulation model for tire rolling resistance was established. Physical output quantity of sensor was collected and processed. Furthermore, rolling resistance test properties were obtained by finite element analysis. The difference in test data was contrasted by changing the relative reference position between the drum and the axle. Linear regression orthogonal was adopted for error-correction. Compared with the laboratory data, trend test shows that the test model can reflect the response relationship between rolling resistance and controlling parameters, so the test model has high reliability. The replicate test shows that the error-correction model for rolling resistance can reduce the equipment system error and improve the measurement accuracy. The simulation results provide practical basis for equipment development.
