I am thinking of designing a thin flat spring.
I am posting to ask for your feedback on whether the calculations were correct. Details are as follows.
A flat spring with a thickness of 0.2, width of 3 and length of 25 and it is cantilevered. The material is SUS304CSP. It needs to support a weight of 15 g. In operation, the load disappears for about 1 minute every 60 minutes.
We are looking for the amount of deflection that does not cause plastic deformation. I think that the limit is 1.98mm after doing some research. Is it correct?
Your question is bout the design calculation of thin flat springs, right?
In the case of flat springs, the deflection under load varies greatly depending on the positions of the fulcrum and the point of use.
In this case, could you send us a drawing or just a sketch showing how you use it? We can send you the design calculation afterwards.
I forgot to attach the attachment to the question above. The flat springs under consideration are for sports prostheses with this shape.
Dear Spring Newbie, flat springs for artificial legs, I got it!
Although we have no experience in designing and manufacturing artificial legs, it is thought that the formulas of U-shaped flat springs can be used. However, determining the point of use (how to apply load) becomes complicated in designing artificial legs.
In this case, normally a meeting to discuss the details is required. For reference, the calculation formulas are described in here.
Please contact us from here so we can discuss the specific design.
