摘要
考虑海水力的作用,建立深海钴结壳微地形的数学模型和采矿头截齿切削过程的数学模型,应用Matlab软件GUI工具编制相应的仿真程序,并通过实验验证仿真模型的正确性和仿真软件的工程有效性。在此基础上,随机生成200个典型海底地形,对采矿头截齿最大载荷的分布特性进行研究;应用置信度为0.95的柯尔莫哥洛夫-斯米尔诺夫(Kolmogorov-Smirnov)检验验证参数估计所得的正态总体与样本数据的一致性。仿真结果表明:截齿最大载荷的分布偏于正态分布;通过置信度为0.95的参数估计,得出最大载荷正态分布概率密度函数的参数μ和σ2及其置信区间;由3σ规则确定了截齿最大载荷以99.73%的概率落于区间[2.027 0 11.110 0],截齿最大载荷基本不超过11.11 kN。
Mathematic model of the tiny terrain covered cobalt-rich crust and the curing process of mining head＇s curing tooth were established by considering the force of sea water, and simulation software was developed by GUI tool of Matlab software to study the distributive properties of maximum load of the curing tooth. The validity of simulation results were tested by experiments. Through statistical analysis, the parameter （μ, σ^2） of normal distribution function of the maximum load, and tested uniformity of the normal population and the sample were obtained. The simulation results of 200 typical tiny terrain indicate that the distribution of maximum load is near normal distribution. The maximum load of curing tooth is from 2.027 0 to 11.110 0 by the probability of 99.73%, in other words, the maximum load of curing tooth is no more than 11.11 kN.
