pyslvs-ui 22.7.0

Description:

pyslvsui 22.7.0

Pyslvs-UI
A GUI-based (PyQt5) tool used to design 2D linkage mechanism.


Planar Linkages Simulation

Python-Solvespace: Kernel from Solvespace with Cython bundle.
Pyslvs: Kernel from Sketch Solve with Cython.


Mechanical Synthesis

Number Synthesis: Combine the attributes of mechanism.
Structural Synthesis: Cython algorithm used to find out structural possibilities of the mechanism.
Dimensional Synthesis: Kernel from the three Cython algorithms (rewrite).


Websites

Getting Started
Executables
Download portable executable file of your platform.
PyPI
pip install pyslvs-ui

Source
Branch master is in development, use stable branch to install stable dependencies directly.
git checkout stable
pip install -e .

There are more detailed instructions in the documentation.
Libraries
Pyslvs has a solver backend that can works without the GUI:
from pyslvs import example_list, parse_vpoints, t_config, expr_solving

# Get example with name
expr, inputs = example_list("Jansen's linkage (Single)")
# Parse the mechanism expression into a list of joint data
vpoints = parse_vpoints(expr)
# Config joint data and control data for the solver
exprs = t_config(vpoints, inputs)
# Solve the position
result = expr_solving(exprs, vpoints, {pair: 0. for pair in inputs})
# Get the result from joint 7
x, y = result[7]
print(x, y) # -43.170055 -91.753226
