Optimization of trammel pendulum model for simulating fluid sloshing in fuel transport vehicles tank

Authors

Abstract

In this paper, a mechanical model is used for simulating fluid sloshing. This method is based on trammel pendulum theory. Then result of overturning moment in the mechanical model compared to numerical analyses in different filling level such as 60%, 70%, 80% and 90% and trammel pendulum equations are corrected and its coefficients are optimized. Then an algorithm for optimizing elliptical tank cross-section based on minimizing overturning moment and fluid c.g. is proposed in the case that its rollover threshold is improved. Operators such as mutation rate and population number affect the accuracy and convergence speed of genetic algorithms. Mutation rate between 4% and 6% and minimum individual of 60 is proposed as the proper operators which lead to a suitable response.
