DANST-PC
Dynamic Analysis of Spur Gear Transmissions
|
 |
|
SOURCE CODE AVAILABLE
|
|
DANST-PC is a program for static and dynamic analysis of spur gear systems. It can be used for parametric studies to predict the static transmission error, dynamic load,
tooth bending stress, and other properties of a pair of external spur gears as they are influenced by operating speed, torque, stiffness, damping, inertia, and tooth profile.
DANST-PC performs geometric modeling and dynamic analysis for low- or high-contact-ratio spur gears. It can simulate gear systems with contact ratios ranging from one
to three.
DANST-PC is based on a four-degree-of-freedom, lumped-mass model of a gear transmission. The model includes driving and driven gears, connecting shafts, motor, and
load. The equations of motion were derived from basic gear geometry and elementary vibration principles. The dynamic solution is found by integrating the equations of
motion. The user is provided with many options, including:
- materials, basic gear geometry, and operating conditions,
- various combinations of tooth profiles
(including three standard forms of tip relief or user-digitized profile modifications),
- static and dynamic analysis, and
- various printed and plotted outputs.
DANST-PC carries the NASA case number LEW-16575. It was originally released as part of the COSMIC collection.
