can anbody tell me about nodal analysis of chassis?

can anbody tell me about nodal analysis of chassis?

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.

Hi, Saim

Welcome

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.
