The formula to calculate the Brake Pedal Force (BPF) is:
\[ BPF = \frac{BDF}{BPR} \]
Where:
Let's say the brake disc force (BDF) is 500 lb-f and the brake pedal ratio (BPR) is 5. Using the formula:
\[ BPF = \frac{500}{5} = 100 \text{ lb-f} \]
So, the brake pedal force is 100 lb-f.
The brake pedal force is the amount measured in pounds or kilograms required for a driver to press the brake pedal to stop their vehicle. For example, if you were driving a car and your brake pedal force was 50 pounds, you would need to apply at least 50 pounds of pressure on your brake pedal to bring your vehicle to a stop.
Definition: The brake pedal ratio is the ratio of the distance from the pedal pivot point to the center of the pedal pad (A) to the distance from the pedal pivot point to the center of the master cylinder pushrod (B).
Formula: $$ \text{Pedal Ratio} = \frac{A}{B} $$
Example: $$ \text{Pedal Ratio} = \frac{12}{3} $$
Definition: This calculation helps determine the force required to bend sheet metal using a press brake.
Formula: $$ F = \frac{1.42 \times TS \times S^2 \times L}{1000 \times V} $$
Example: $$ F = \frac{1.42 \times 400 \times 4^2 \times 1000}{1000 \times 32} $$
Definition: The braking force is the force applied by the brakes to stop a vehicle.
Formula: $$ F = \frac{0.5 \times m \times v^2}{d} $$
Example: $$ F = \frac{0.5 \times 1500 \times 20^2}{50} $$
Definition: The brake pedal ratio is the ratio of the distance from the pedal pivot point to the center of the pedal pad (A) to the distance from the pedal pivot point to the center of the master cylinder pushrod (B).
Formula: $$ \text{Pedal Ratio} = \frac{A}{B} $$
Example: $$ \text{Pedal Ratio} = \frac{14}{2.3} $$
Definition: The braking force is the force applied by the brakes to stop a vehicle.
Formula: $$ F = m \times a $$
Example: $$ F = 1500 \times 9.8 $$
