HLrainflow

A simple and efficient implementation of the Rainflow counting algorithm for fatigue analysis in Python.

Features

• Rainflow cycle counting for fatigue analysis
• Lightweight and dependency-free
• Supports peak-valley sequences or raw time-series input
• Easy to test and extend

Installation

You can install the package via pip:

pip install HLrainflow

Usage

from HLrainflow import rainflow
Sample1=[-2,1,-3,5,-1,3,-4,4,-2]
peak=Sample1
hl=rainflow.HL()
hl.SetPeak(peak)
halfR,halfM=hl.hloop()
print('half range=',halfR)
print('half mean=',halfM)  

Example Output

half range= [4.0, 4.0, 3.0, 4.0, 8.0, 9.0, 8.0, 6.0]
half mean= [1.0, 1.0, -0.5, -1.0, 1.0, 0.5, 0.0, 1.0]
