I need advice on designing frames/chassis
Hello,
I am fresh graduate from hybrid department, which includes mechanical engineering.
I am working on my first project.
In short, it’s a mobile machine that’s used to move light weight 100-250 kgs— you can think of it as a simple mobile crane.
I have started with the chassis/frame design, but unfortunately when I think about it, I can’t link it to anything I studied in uni in those statics or material strength courses.
I tried to use Solidworks simulation to get a sense on how different chassis design affects the overall strength of the frame, but again I am not sure.
I want to sharpen my mechanical design skills in that type of design as it’s very common and necessary, so by learning how to do hands calculations for such design. Thus, to summarise it up, firstly, I need some advice on the common design principles for frames/chasiss if such a thing exists (e.g. diagonal chassis is good for X, vertical beams chassis is bad for Y, weight distribution is dependent on X..)
Also, I need to learn the topic name or the course material that will help in designing such parts. I can learn very well from examples or books, but when I searched it up, I didn’t find anything straightforward.
Here are some pictures of the chassis and simulation results.
