摘　　要：介绍了一种新型磁悬浮静力光轮精碾压路机的结构及其工作原理,分析了该压路机压力控制油缸同步性对碾压位置和碾压力的影响,并以质量为250 kg、悬浮气隙为10 mm的磁悬浮碾轮为例,利用ANSYS分析软件分析了压力控制油缸同步性对其碾压力的影响。分析结果表明:当压力控制油缸同步性误差不超过0.80 mm时,实际碾压力与理论设计值的误差小于5%,对磁悬浮控制系统稳定性的影响较小,为磁悬浮静力光轮精碾压路机的结构优化提供了理论依据。The structure and operational principle of maglev static smooth-wheel precision roller was introduced. The influence of the hydro-cylinder synchronization on the rolling position accuracy and pressure were analyzed. The influence of the hydro-cylinder synchronization on the maglev roller′ s pressure was analyzed by ANSYS when the mass of maglev roller and the suspension air gap were 250 kg and 10 mm, respectively. The analytical result showed that the error between the actual grinding pressure and theoretical roller′ s pressure was below 5% when the hydro-cylinder synchronization error was no more than0.80 mm, and the hydro-cylinder synchronization on the maglev roller′s pressure precision was fewer. It provided a theoretical basis for the structural optimization of maglev static smooth-wheel precision roller.
