High Duty Bolted Joint Analysis
The bolt analysis tool (BAT) is an input file based Python command line tool for multi-bolt analyses. It is designed primarily for the space industry (ESA), but of course it can be used for all kinds of high duty bolted joint analyses.
Standards implemented in BAT (current status includes concentric axially loaded joints only):
- ESA PSS-03-208 Issue 1 (December 1989)
- ECSS-E-HB-32-23A 16 April 2010
The user manual can be found here: BAT User-Manual
It supports Python 3.0+ and uses pyQT5, matplotlib and numpy.
- Download or clone the repository
https://github.com/misams/BAT.git. - Run the BAT software with the included test input file
input_test_1.inp.
$ python bat_main.py -i input_test_1.inp- After sucessfully running
bat_main.pyyou get the analysis result directly to your terminal and to the output fileoutput_test.outor you redefine the output file name.
$ python bat_main.py -i input_test_1.inp -o output_test_1.out- To show all available command line options - type the following.
$ python bat_main.py --help- Download or clone the repository
https://github.com/misams/BAT.git. - Run the BAT software with the GUI-option.
$ python bat_main.py --gui
