武汉地铁11号线列车转向架。因为本线路供电制式为轨道供电,所以转向架还附带受流器。
轉向架(英文:Bogie),又称台车(来自日文),是铁道车辆上最重要的部件之一,它直接承载车体自重和载重,引导车辆沿铁路轨道运行,保证车辆顺利通过曲线,并具有减缓来自车辆运行时带来震动和冲击的作用,因此转向架的设计也直接决定了车辆的稳定性和车辆乘坐的舒适性。
簡述
每組轉向架多擁有2或3條車軸,並常安裝在列車車廂前後部。當列車經過彎道時,前後兩組轉向架會順著軌道之曲線轉動,使列車能靈活通過彎道。如果是電力/柴油電力鐵路機車或者是動力分散式車輛的動力車卡,轉向架的每條車軸則設有電動機。
法国TGV高速列車使用的轉向架,採用關節式轉向架,即每組轉向架置於兩節客車車廂之間。
三軸轉向架多出現於鐵路機車及貨車上,其好處是牽引力高及黏著力強,但這種設計會降低通過急彎的靈活性,且對輪對的磨耗也較高。為增加這類機車的靈活性,因此出現了「徑向轉向架」,即單一架子的前後車軸可以轉向。

1 I having trouble getting my ResourceDictionary.MergedDictionaries to load from app.xaml. My WPF app has a static class with a Main defined and startup object set to it. Within Main I created an instance of App and run it. The override OnStartup fires and the mainwindow.cs InitializeComponent gives the error "Message "Cannot find resource named 'MaterialDesignFloatingActionMiniAccentButton'. If I put the resources in the mainwindow.xaml everything is fine, but I wanted them to load at the app level so I they are not in each page. Any help appreciated. public partial class App protected override void OnStartup(StartupEventArgs e) base.OnStartup(e); var app = new MainWindow(); var context = new MainWindowViewModel(); app.DataContext = context; app.Show(); from the Main.. var app = new App(); app.Run(); app.xaml.. <Application x:Class="GS.Server.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:...
up vote 2 down vote favorite There is a clear pattern that show for two separate subsets (set of columns); If one value is missing in a column, values of other columns in the same subset are missing for any row. Here is a visualization of missing data My tries up until now, I used ycimpute library to learn from other values, and applied Iterforest. I noted, score of Logistic regression is so weak (0.6) and thought Iterforest might not learn enough or anyway, except from outer subset which might not be enough? for example the subset with 11 columns might learn from the other columns but not from within it's members, and the same goes for the subset with four columns. This bar plot show better quantity of missings So of course, dealing with missings is better than dropping rows because It would affect my prediction which does contain the same missings quantity relatively. Any better way to deal with these ? [EDIT] The nullity pattern is confirmed: machine-learning cor...
