Rail Track Analysis Model Wizard
Modeling Option
Element Length : Unit length for modeling is entered. Based on the entered element length, the effective length of rails and the resistance of ballast in Multi-Linear elastic Link are determined.
Unit Setting : Element length units can be selected from kN/m and kips/in.
Value greater than 2m is not permitted as per UIC specification.
Analysis Model Option
Stress Check Model Option : Option that creates model files for additional stress check.
Simplified Separate Analysis Model : Creates model files for individual analysis.
xxx_Temp.mcb : model file that contains boundary conditions and a temperature load without train load.
xxx_Train.mcb : model file that contains boundary conditions and acceleration/braking/vertical loads as well as train load.
Complete Analysis : Creates model files for construction stages and complete state model file.
xxx_Complete.mcb : Model file that contains Unloaded stage (without train load) and Loaded stage (with train load)
Displacement Check Model Option : Option that creates model files for displacement check. For the case of Unloaded Condition of Ballast Bed, the resistance of ballast is different from that of Stress Check case. Displacement checks are only available in Simplified Sperate Analysis Model.
Relative Longitudinal Displacement Component due to Acceleration and Braking Alone : provides model files with individual analysis for longitudinal displacements between decks and rails due to acceleration and braking loads.
xxx_Add1_RelativeDisp.mcb : Displacement check file that contains acceleration/braking loads
Relative Longitudinal Displacement Component due to Vertical Effects : provides model files with individual analysis for longitudinal displacements due to vertical train loads.
xxx_Add2_RotationAngle.mcb : Displacement check file that contains vertical effects.
Relative Longitudinal Displacement Component at Rail Expansion Joints : provides model files considering rail expansion joint with individual analysis for longitudinal displacements. (Temperature load in both rail and deck must be entered.)
xxx_Add3_ExpansionJoint.mcb : Displacement check file that contains temperature loads (rail/bridge).
Rail Break Gap Size : Model file to check Rail Break Gap Size. In order to check the Rail Break Gap Size, the location of Rail Break needs to be entered.
xxx_Add4_RailBreakGapSize.mcb : Rail Break Gap Size check file.
When Moving Load Data is checked, files are added as many as the Number of Track Loading Locations input
