Il Calcolatore della forza di smorzamento is a tool used to determine the force exerted by a damper in an oscillating system. It helps engineers, physicists, and researchers analyze the effect of damping in mechanical systems, ensuring stabilità and reducing excessive vibrations.
Damping force is crucial in mechanical and strutturale applications such as shock absorbers in vehicles, seismic dampers in buildings, and vibration control in machinery. By using this calculator, engineers can optimize damping mechanisms to enhance efficiency and safety.
This tool simplifies the calculation of damping force by incorporating peak velocity, frequenza angolare, and time, making it easier to analyze dynamic systems.
Formula for Damping Force Calculator
The damping force is calculated using the following formula:
Damping Force (N) = Damping Coefficient × Peak Velocity × sin(ωt)
Dove:
- Damping Force (N) = The force exerted by the damper in newtons
- Damping Coefficient (Ns/m) = Resistance force per unit velocity
- Peak Velocity (m/s) = Maximum velocity during oscillazione
- ω (rad/s) = Angular frequency, calculated as ω = 2π × Frequency
- t (seconds) = Time instant
This equation allows engineers to determine how much force a damper exerts at different points in time during an oscillation cycle.

Example of Damping Force Calculator
A mechanical system has the following properties:
- Coefficiente di smorzamento = 200 Ns/m
- Velocità di picco = 3 m/s
- Frequenza = 2 Hz
- Ora = 0.2 secondi
Step 1: Calculate the Angular Frequency
ω = 2π × Frequency
ω = 2 × 3.1416 × 2 = 12.57 rad / s
Step 2: Apply Values to the Formula
Damping Force = Damping Coefficient × Peak Velocity × sin(ωt)
Damping Force = 200 × 3 × sin(12.57 × 0.2) = 352.2 N
This means the damper exerts a force of 352.2 Newton at t = 0.2 secondi.
