摘要
针对钢带式轮胎试验台中钢带支撑刚度对道路试验结果的影响,设计一种气轴承支撑装置,并基于CFD数值仿真和正交试验,研究输入孔径、输入压强、钢带速度、楔形角度对轮胎试验台气轴承支撑装置承载压力的影响。仿真分析了承载压力随各个影响因子的变化规律,其结果显示钢带速度和楔形角度对承载压力影响较小,输入孔径和输入压力是承载压力的主要影响因素。在各个影响因子变化规律基础上,基于正交试验优化方法,以最小输入压强为目标函数,得到最优的支撑件结构。
Air bearing suspension support characteristics of suspension belt type road simulator are established.The model is simulated using FLUENT solver and orthogonal test.The load pressure′s effects of feed hole diameter,feed pres sure,steel belt speed and the angle of the wedge gap on the suspension support characteristics on the dynamic lubricat ing characteristic parameters are analyzed.It shows that feed hole diameter and high feed pressure increases the load pressure while the fluid bearing pressure changes with different influence factors.The sensitivity that various factors af fect the fluid bearing pressure is analyzed by doing the orthogonal test.The optimal supporting structure is obtained by the minimum feed pressure target function.
