Hi. First of all, I am not a student majoring in Mechanical Engineering. So please understand my ignorant.
I am simulating of radial spring with overhanging(?) beam like the first image.
For simulation, I used the equation below.
Factor N = (4 * E * δ * w * t^3 * 10^9) / (g * m * L^3)
Material = Ti-6Al-4V,
E (GPA) = 121 GPa: E
Length (mm) = 33.00: L
Thickness (mm) = 0.4 : t
Deflection (mm) = 1.0 mm: d
Total deflection δ = deflection d + thickness t = 1.4
Preload = (factor) x (weight of element)
mass of the lens g is 202.21 (g)
width of spring w is 9.0 (mm)
In my case, Factor N is 6.0, total force of center is 11.91N.
But like the second, third picture, Deflection of center is 1.33~1.34 mm.
So I modeled many cases like the fourth picture, also a triangle, trapezoid. But the result is not correct or failed to simulate because of large displacement.
Please help me to model the finest result. I really stuck at this simple simulation...
Thank you for reading this.
