A Comprehensive Parameter Scan Dataset of Stable Islands in a Double Pendulum System
Listed in ScienceDB
This dataset systematically investigates the phase-space structure of a classical double pendulum system through large-scale numerical simulations across three rounds of scanning.
Description
Round 1 fixes the initial angle at 90° with 100 mass ratios (G1-G100) on a 32×32 grid. Round 2 covers 18 initial angles from 0° to 180°, each with 100 mass ratios on a 32×32 grid.
Round 3 performs high-resolution 128×128 scanning (G86.5-G87.5) targeting the stability island region near 60°. Each simulation records pendulum angle trajectories and statistical summaries at 20 temporal sampling points (10s-1800s), totaling approximately 1900 complete simulations. Data is provided in JSON format with an accompanying CSV summary table.
