The "Mechanical Design Toolbox" concept has evolved. Modern instructors now rewrite Kim’s toolbox in using:
Covers 2D and 3D stress analysis using Mohr's circle, as well as static and fatigue failure theories (such as MSS and DE theories).
if n < 1.5 [new_diameter] = iterate_shaft_diameter(Se, Sut, sigma_a, sigma_m); fprintf('Increase diameter to %.2f mm\n', new_diameter); end The "Mechanical Design Toolbox" concept has evolved
% Check safety factor (Goodman) n = goodman(sigma_a, sigma_m, Se, Sut);
Developed by Dr. Kyu-Jung Kim at Cal Poly Pomona since the early 2000s, the Mechanical Design Toolbox (MDT) is a specialized simulation and calculation tool. It is specifically engineered to: Kyu-Jung Kim at Cal Poly Pomona since the
Here is a detailed report on by Kyu-Jung Kim.
% Calculate alternating and midrange stresses [sigma_a, sigma_m] = stress_state(M_bending, Torque, diameter, Kf_bend, Kf_torsion); The value of Kim's work lies in the
If you are using this for a class or research, focus on and inter-dependencies between shafts and bearings . The value of Kim's work lies in the automation of the feedback loop: changing a gear load instantly updates the bearing life calculation, which is the central theme of modern machine design.
