Calculation of arcuate thin leaf spring
2020/12/06 categories:Mechanical design| tags:Mechanical design|
This is a calculation form for arc-shaped thin leaf springs. Enter the modulus of lateral elasticity from the linear and click the Calculate button to calculate the values in the following rows.
| Item | Formula | Value | Unit |
|---|---|---|---|
| Width | $ b $ | $ mm $ | |
| Thickness | $ h $ | $ mm $ | |
| Radius | $ R $ | $ $ | |
| Angle | $ \alpha $ | $ ° $ | |
| YYoung’s modulus | $ E $ | $ N/mm^2 $ | |
| Poisson’s ratio | $ \nu $ | $ $ | |
| Flexural rigidity of thin plate | $ B = \frac{bh^3E}{12(1-\nu)} $ | $ $ | |
| Load | $ P $ | $ N $ | |
| Calculate deflection from load | $ \delta=(\frac{PR^3}{B}) \{ (\pi-\alpha)(1+2cos^2\alpha)+1.5sin2\alpha \} $ | $ mm $ | |
| Deflection | $ \delta $ | $ mm $ | |
| Calculate the load from the deflection | $ P=\frac{\delta \cdot B}{ \{ (\pi-\alpha)(1+2cos^2\alpha)+1.5sin2\alpha \} R^3 } $ | $ N $ |
