摘要
目前四轮定位仪的测量由于只能依靠空间几何模型推得的近似线性公式间接测量,而线性公式并不符合车轮实际运动轨迹,因此会产生一定的理论误差。本文对四轮定位测量的误差进行了分析,提出了减少误差的新的测量方法,为生产企业提供了设计参考,为保证汽车维修质量必将起到积极作用。
Recently, the measurement of four-wheel alignment can be achieved indirectly only by the approximate linear formulas deduced from space geometry, model, which is inconsistent with actual moving tracking of wheels and produces theoretical error. This paper analyzes the errors of the measurement of four-wheel alignment and gives a new method to reduce the errors, which supplies a design reference basis for enterprises and plays an active role in ensuring the quality of vehicle maintenance.
