摘要
橡胶履带轮用于更换轮式车辆的轮胎,以提高其越野性能。为避免脱带和履带过度拉伸,使履带周长与轮系相匹配,提出了一种基于轮系中各轮相对位置变化的橡胶履带周长建模方法。在多种地形条件下,使用多相机视频测量系统对轮系中各轮上标记点进行追踪,利用采集到的标记点坐标重构各轮轴线,并进一步采用该方法重建履带周长。在平整钢板上的试验结果表明,由于履带弯曲刚度不均匀,构建的履带平均周长为3 791.62 mm,标准差为3.51 mm,比履带实际周长3 812 mm略小,且略有波动。根据在多种地形条件下的测量结果构建的履带周长,其标准差与平整钢板上一致,均为3.5 mm左右。平均值在3 787.78~3 794.75 mm之间,基本与平整钢板上的履带平均周长一致。因此,橡胶履带周长建模方法能够在多种地形条件下评估履带周长,为履带轮设计提供依据。
