The formula to calculate the Dual Spring Rate (DSR) is:
\[ \text{DSR} = \frac{\text{T} \times \text{B}}{\text{T} + \text{B}} \]
Where:
The dual spring rate is the effective spring rate of two springs combined in parallel. It is calculated by dividing the product of the top spring rate and the bottom spring rate by the sum of these two rates. This calculation is useful in mechanical systems where springs are used to provide a specific stiffness or compliance.
Let's assume the following values:
Using the formula:
\[ \text{DSR} = \frac{100 \times 200}{100 + 200} = \frac{20000}{300} \approx 66.67 \]
The Dual Spring Rate (DSR) is approximately 66.67 N/m.
