can anbody tell me about nodal analysis of chassis?
This is not the answer to the question. only recommended.
If you want help.
You should give some more details, screenshot, file, information about what you have done so far .....
Someone who has experience with the analysis can only help.
Thank you. But i am starting this nodal analysis from scratch so I have no idea about it. So i want anybody to guide me or to give me reports on nodal analysis.
Do you mean Modal analysis?
No, its nodal analysis which is done on each node of chassis separately.
You start with a free body diagram of the frame with lines representing the members and typically this is pin jointed to make it solvable, then you solve for for all the axial forces (as they are two force members) and then you make sure that non of the compressive loads can cause failure (buckling) or you can compute the section modulus to avoid buckling with margin). The force reactions can then be used to stress any of the members and size the connection details. Its pretty basic and pretty old school to do it by hand but that is the analysis as I recall. If you have lots of members not in a regular pattern (like say a lattice member) it might be a lot less work to use an FEA program or a matrix solver of some sort.
Is this for school? Otherwise yikes!
