Stress Analysis Student Project

[ozgurakkas]

Hi All,

I am going to perform stress analysis on a helicopter landing gear. My job is to find one specific landing gear, study its design, analyze and through tools we learned in the strength of materials class, redesign the gear to improve it.

If you have knowledge of this sort of engineering analysis, can you suggest me some guide lines. For example, how do I increase strength in bearing the stress. Is it possible just by choosing another type material. How would I approach to this If there were financial constraints.

I am also trying to show the improvisation through a computer program. For example, landing gear stress and shear regions before and after. Can you suggest me a program, perhaps one easy-ier to figure out?

It s been a long post. Thank you for your patience and suggestions.

If you have a free choice about the type of landing gear, I suggest you choose a helicopter that has fixed skids for landing, not wheels. In a "strength of materials" type of course, you may not have studied all the things that are important to analyze and redesign wheeled landing gear.

If you have studied the dynamics of multi-degree-of-freedom systems including damping, and their response to impulsve loads, then you can ignore my advice, but I would guess that you haven't studied those things in a strength of materials course, as compared with an BS level Mech Eng dynamics course.

This was helpful. I will take your suggestion into consideration. Thank you.
