Objective
2
Little research has been conducted on the rational parameter setting of micro harmonic reducers. To improve the force condition and transmission performance of micro harmonic flexsplines
a neural network-based parameter optimization method was proposed.
Methods
2
Firstly
a flexspline simulation model was established
and optimization parameters were screened using local sensitivity analysis method. Then
the artificial neural network was optimized by the genetic algorithm
and a mapping model between the optimization parameters and flexspline stress as well as flexspline stiffness was constructed. Finally
through model analysis
the global sensitivity of the optimization parameters was obtained
and the relation between the optimization parameters and flexspline stress as well as flexspline stiffness was revealed.
Results
2
The calculation results show that the optimization of flexspline structural parameters based on neural network-based global sensitivity analysis can effectively alleviate the stress concentration of the flexspline
the stiffness of the flexspline is improved
and the transmission performance of the harmonic reducer is enhanced.
