1. Check the material properties of the rail component and calculate the speed of sound in steel rail=_______

Material name= Steel

Density (ρ) (rho)= 0.0078 gm/mm3

Young's modulus(E)= 210000 Mpa

Speed of sound in rail (c)= root(E/rho)=root (210000/0.0078)=5188.75 mm/ms

2. The length of the rail is about 1000 mm.calculate the time takes for a shock wave to travel from one end of the rail to the other.

Length of rail= 1000mm

Speed of sound/ shock wave= 5188.75 mm/ms

Time taken for the shock wave to travel from one end to another end of rail ,t = 1000/5188.75=0.1927 ms

3) Time for sound to travel length of rail is = 0.1927ms

4.Edit the engine file so that the stress wave can be monitored, moving from one end of the rail to the other during impact -this will require a termination time equal to the time it takes for the sound to travel the length of the rail(set on/RUN card)

5.Set the frequency of animation output to a time that will give 20 animation steps(/ANIM/DT)

frequency=(l/c)*time
=(1/0.1927)*20
=104 Hz

6.Change /print -10.

7.3d meshing tetra mesh and hex mesh

Aim

Create 1D elements in the geometry.

Procedure

Created the surface for the geometry and mesh the component.Created the 1D element on both components rod, beam, spring, spot weld, seam weld, etc.

Conclusion

The necessary connections have been carried out.

Aim

To create the hexa mesh for the component

Procedure

One side of the surface mesh generated and using solid map, linear solid, solid mesh, element offset, spin, etc, has been used to create the hexa mesh for the component.
