Train Dynamic Load Table

▒ Overview

Create a train dynamic load and apply it to the analysis model.

The train dynamic load can be created in the same was as Dynamic Analysis > Tools > Create Dynamic Load Data Generator > Train Dynamic Load.

The created load judges the train velocity and spacing between nodes and automatically applies it to the analysis model as a dynamic nodal.

▒ Methodology

Auto generation and application of a train dynamic load

[Object] : Select the edge or node the train dynamic load passes through, and select the start and end nodes.

[Name]: Define the train type name.

[Train Type] : Select the type of train. 6 basic DB (Mugunghwa Train, 2 diesel cars, Korea), [Saemaeul Train, 8 cars, Korea), [KTX, 20 cars, Korea), [EL-18 Standard, 6 cars, Korea), [EL-18 Standard, 8 cars, Korea), [EL-18 Standard, 10 cars, Korea) are provided and the user can directly input the length/force depending on the number of wheels.

[Number of Wheels] : Stands for the number of wheels on the train. It is the same as the added number on the table.

[Train Velocity] : Input the velocity of the train.

[Time] : Input the time the train dynamic load is applied.

[Direction] : Input the direction in which the train dynamic load is applied. It is generally applied in the gravitational direction and thus the user can specify it in the same direction as the gravitational direction of the 3D model.

[Dynamic Load Set] : Input the name that will be registered on the load set.
