Assignment
Double Pendulum
This is a PyQt Application simulating the motion of double pendulums. This application uses Runge-Kutta fourth-order numerical solution method to calculate pendulums' position.
-
Instruction :
In this application, the user can adjust the pendulum mass, the cycloid length, the initial phase (theta), and the initial angular velocity of the two pendulums by adjusting the slider bar or by typing a value on the left side of the interface, and can adjust the magnitude of the gravitational acceleration.- Press "Default" to restore the default values
- Press "Start" to start the simulation
- Press "Pause" to pause the simulation
- Press "Resume" to resume the simulation
- Press "Stop" to stop the simulation and the pendulums return to the initial states
-
Physical Quantities :
All physical quantities are in use of International System of Units (SI) and angular dimensions are in use of degrees ($^{\circ}$ ).- Range of pendulum mass is
$0.01-10.00$ kg - Cycloid length is
$0.01-2.00$ m - Initial phase is
$-180.0-180.0^{\circ}$ - Initial angular velocity is
$-200.0-200.0^{\circ}$ /s
( the phase is$0$ in the vertical downward direction, and increases in the clockwise direction ) - Range of gravitational acceleration is
$1.00-20.00$ m/s$^{2}$ - Default pendulum mass, cycloid length, initial phase and initial angular velocity is
$1.00$ kg ,$1.00$ m ,$90.0^{\circ}$ ,$0.0^{\circ}$ /s , respectively. Default gravitational acceleration is$9.80$ m/s$^{2}$.
- Range of pendulum mass is
