轮辋宽度对轮胎不平衡量解算的影响
Research on the Impacts of Rim Width on the Tire Dynamic Unbalance

不同规格的轮胎混装在线检测的需要使得多级轮辋应运而生。针对该方式下忽略轮辋宽度影响造成的不同厂家设备检测结果的差异，考虑轮辋宽度的影响，改进完善轮胎动平衡试验机的动力学模型。笔者探讨动平衡试验机的量标定算法，基于最小二乘复影响系数法求解标定系数，推导出不同轮辋层和不同轮辋宽度下不平衡量的等效算法。同时，根据轮胎规格参数设计机械锁紧装置，采用精密伺服控制技术实现了轮辋宽度的在线调节。实验结果和工程应用验证了该算法的可行性、有效性和适用性，也为不同厂家设备检测结果的一致性奠定了基础。
The online dynamic balance detection of various tires calls for the multi rim combination method. In light of measurement differences, the dynamic model of the test machine was improved considering the rim width. The common calibration algorithm based on the least squares complex number influence coefficient calibration method was analyzed. The unbalance equivalent algorithms under different rim diameters and widths were derived. The mechanical locking device was designed according to the tire specification parameters. In addition, the servo system realized the online rim width adjustment. The experimental results and engineering applications verify the feasibility and validity of the algorithm.
