摘要
针对很难精确计算多轴或整车振动模型的车轮静载荷,从而影响汽车行驶平顺性研究这一问题,提出利用计算结构力学中通过约束处理获得反力而给出汽车静止时只受自身重力作用条件下车轮静载荷的求解方法。实例求解验证结果表明,该求解方法不仅适用于求解1/4汽车模型和1/2双轴模型的车轮静载荷,更适用于求解复杂多轴汽车结构模型的车轮静载荷。
For it is difficult to precisely calculate static load of wheels for multi-axle or complete vehicle vibration model as to interfere with the study of ride comfort,this paper raises a solution of calculating static load of vehicle wheels when the vehicle is static and only bears self gravity by utilizing constraint disposal in computational structural mechanics to obtain reacting foree.The result by examples shows that the method is not only applied to the calculation of wheel static load for 1/4 vehicle model and 1/2 dual-axle model,but also for the complicated multi-axle vehicle model.
