多轴车辆轮荷计算方法研究
|
摘要
针对以往多轴车辆设计中只计算轴荷的情况,提出了计算多轴车辆轮荷的计算方法。通过分析多轴车辆空间受力情况并作适当假设,建立了多轴车辆轮荷计算模型,利用二维变形协调方程推导了轮荷计算公式。将由该公式计算的某多轴车辆轮荷与实际称重结果进行了对比,结果表明,所建立的轮荷计算公式能够较好地反映每个车轮实际的承载情况,可用于多轴车辆的整车设计、校核和优化。
In the last, only the axle load was calculated in the design of the multi-axle vehicles. In this paper, the method of calculating the wheel load for multi-axle vehicles is proposed. The model of wheel load calculation is established after making spatial force analysis of multi-axle vehicles, and the formula for calculating the wheel load is deduced with 2D deformation compatibility equation. Comparing the result from the formula with the real load of a multiaxle vehicle, which shows that the established wheel load calculation formula truly reflects real load bearing condition of each wheel, and this formula can be applied to design, check and optimization of multi-axle vehicles.
