| 摘 要： | 针对汽车曲线行驶状态轴距差检测仪校准方法的问题,研究了曲线行驶时轴距差的检测模型,提出了一种带有模拟并计量前轮转角功能进而实现汽车定轴距差曲线行驶的校准方法。该方法采用轴销的中心作为前轮回转中心,有效避免了由于前轮转动导致的校准装置轴距改变。研发了汽车曲线行驶状态轴距差检测仪的校准装置,完成了校准点分别为0、1、3、5、10、20mm时光敏式轴距差检测仪的校准试验,证明了汽车曲线行驶状态轴距差检测仪校准方法的可行性和准确性。

| Abstract: | Focus on the problem of calibration method of wheelbase difference tester while vehicle is driven in a curve,the detection method was studied for a vehicle with curve driving status.A calibration method with the feature of simulating and measuring the front wheel turning angle was presented to realizing the calibration method for a vehicle with curve driving status.The method adopted shaft center as the rotation center of the front wheel,which avoided the wheelbase displacement alteration of calibration apparatus caused by front wheel turning.The calibration apparatus of wheelbase difference tester for curve driving vehicle was developed.The calibration experiments of photosensitive wheelbase difference tester was performed on a with the calibration points of 0、1、3、5、10 and 20 mm,respectively.The feasibility and accuracy of the calibration method of wheelbase difference tester method for curve driving vehicle are inspected. |
