3) radial development
径向展开
4) controlled radial bogie
可控径向转向架
1.
The mathematic model for the passenger car with controlled radial bogies is set up.
建立了可控径向转向架客车的数学模型。
2.
The simulation results show that,when a tilting train negotiates a curve at a speed 30% higher than a normal train,the application of forced steering bogies can effectively reduce the wheel-rail wear and improve the dynamics performance,the actively controlled radial bogie can have the similar effect as the forced steer.
可控径向转向架能方便地调整径向增益,且在作动器卸荷后具有与自导向径向转向架一样的性能。
