In order to accurately track the movement of heavy objects falling into the water, this paper,based on a mathematical model of mechanics,uses optimization theory to solve the model as well as comparing the results with the test.The results show that the weight of the sinking from numerical simulation and test track there is a certain gap.To this end,this paper presents an improved model,that is,to improve the original model by adding noise. The modle,fitted with a noise,is in good agreement with the experimental values obtained. Moreover,it verifies the reliability and accuracy of the model,which can be applied to the actual breach closure of the numerical simulation of heavy movement.
