Week 2 Railwheel and Track

Static structural analysis on Railwheel and track setup

Geometry imported

Railwheel - track - shaft

Material:

Contacts defined:-

1) between wheel and track

type - frictional

frictional co-efficient - 0.3

2) between shaft and wheel

type - frictionless

Joints applies:-

1) Fixed - ground to runningrail

2) translational - ground to shaft

3) Planar - ground to wheel

MESHING - Overall meshing has been done with 35mm element size , whereas contact surfaces has been given a element size of 20mm using face meshing.

following analysis setting has been applied

number of steps - 5

from step 2 to 5

auto time stepping - on

define by - time

minimum time step - 1e-3s

maximum time step - 0.1s

carry over time step - on

CASE 1 :

comparison between bearing load applied - 5e5 N against the gravity VS 1e5 against the gravity

Joint-displacement - in tabular form - 100mm per step

CASE2: for user defined result we have create a expression using inbuilt worksheet for total deformation , and found out similarity between both analysis
