Project - 2 - Meshing on the suspension Assembly
Project 2 - Rear Suspension system
Aim: To create surface meshing & then volume for it & for some parts mid surface & mashing. Then Creating connections & create symmetry of given model.
Procedure:
1. Imported model & checked properties & cons resolution.
2. Selected 1st property which is suspension assembly & started working on it firstly. Applyed Topo to attach surfaces & then checked geometrical errors.
3. Observed the geometry & took some measurents. Those portions/ parts below 5 mm used to extract mid surface & above direct surface meshing. Separated those surfaces & started working on Mid surface generation, for which used Offset tool & generated Mid surface at 1.5 mm. Next gave all quality parameters & Mesh parameters & moved to mesh generation using Best tool & cleared quality issues.
4. Then started working on non uniform surfaces for that gave quality criteria & Mesh parameters with Tria.
Here also used Best option to generate mesh . One by one attached surfaces meshed & simulteneously checked qualities.
5. Then represented suspension spring 1st created curve using Curves Middle then made COG point. Then in Nastran selected Element C BAR & selected Curve box then selected curve then middle click & selected COG. Then specified element lenght, then created new PID. While crating PID for it in that it automatically captured Area & MI. Then 1D bar created. Then in Quality criteria- Presentation parameters clicked on Line element as Solid & the 1D bar is represented as solid.
6. And here after proveded RBE2 connections.
7. After that moved to Tyre where need to do surface meshing. Changed quality & mesh parameters & did surface meshing with trias. checked quality.
8. Then selected PID of Rim with same quality & mesh parameters as tyre generated meshing & cleared quality issues.
9. In Volume Mesh used define to create volume mesh, it showed all volume/solid PID automatically. One by one edited to Tetra Rapid & remeshed by right clicking on that perticular PID.
10. By unselecting parent geometry gave remaining connection, also used Lock manager to remain in working area.
11. In in finale used Transform - Copy to make symmetry of meshed suspension assembly.
Outcomes & Difficulties occured during working:
It was really interesting hours working on it. Learned lots of new things like modelling spring, how to clear problems which occures during working, etc.
I got stuck during creating volume mesh because of some geometrical errors. Also still confused with connection but will clear it soon.
Some Quality issues was unable to clear. Also problems in surface defeaturing.
Conclusion:
It took more time. Need to practice more & clear some technical terms.
