Vertical Tyre Axle Rate given Roll Rate of Suspension with Anti-Roll Bar Solution

Follow our step by step solution on how to calculate Vertical Tyre Axle Rate given Roll Rate of Suspension with Anti-Roll Bar?

FIRST Step Consider the formula

K w = \frac{\frac{K Φ \cdot K t \cdot \frac{{t R}^{2}}{2}}{K t \cdot \frac{{t R}^{2}}{2} - K Φ} - R arb}{\frac{{T s}^{2}}{2}}

Next Step Substitute values of Variables

∴

K w = \frac{\frac{10297.43Nm/rad \cdot 321300N/m \cdot \frac{{0.4m}^{2}}{2}}{321300N/m \cdot \frac{{0.4m}^{2}}{2} - 10297.43Nm/rad} - 4881.6Nm/rad}{\frac{{0.9m}^{2}}{2}}

Next Step Prepare to Evaluate

∴

K w = \frac{\frac{10297.43 \cdot 321300 \cdot \frac{{0.4}^{2}}{2}}{321300 \cdot \frac{{0.4}^{2}}{2} - 10297.43} - 4881.6}{\frac{{0.9}^{2}}{2}}

Next Step Evaluate

∴

K w = 30366.4627233706N/m

LAST Step Rounding Answer

∴

K w = 30366.4627N/m
