一、问题的提出自行车前叉是自行车中的重要部件之一,其成品件的精度要求如图1所示。为达到此要求,目前国内自行车行业中,都在浴焊、机械加工后安排人工校正工序。使用这种方法存在着三个缺点:其一,工人劳动强度大;其二,校正后易引起“恢复”变形;其三,校正质量受操作者水平和工装质量的影响。为此,我们提出了衰减振动校正法,从 First, the question raised Bicycle front fork is one of the important parts of the bicycle, the precision of its finished parts as shown in Figure 1. In order to meet this requirement, at present, in the bicycle industry in China, the procedures of manual correction are arranged after bath welding and machining. There are three drawbacks to using this method: first, workers are labor-intensive; second, they tend to cause “recovery” deformation after correction; and third, the quality of calibration is affected by the level of the operator and the quality of the tooling. To this end, we propose a method of attenuation vibration correction, from
