Analyse Of Loads's Spectrum Of Continuous Miner's Cutting Drum And Fuzzy Optimization Design To Parameters

On the foundation of the theory which is about the single pick's average load, analyzed loads's probability distribution and relevance when a single pick cuts various coal rock, on this basis, Utilizing the stochastic process theory ,set up the mathematical model about the single pick's stochastic loads. Under the coordinate of Descartes, analyzed the loads of continuous mine's cutting drum,and set up the mathematical model about drum's stochastic strength and moment whicn include three direction. Regard MATLAB software as the platform, write each stochastic loads's simulation programme. Analyzed the spectrum of simulated load in frequency field,time field and amplitude field,studied load's density of probability distribution, since (or mutual) relevance,since (or mutual) density of the power spectrum. And analyzed each parameter's influence to base wave frequency and other main frequency of loads. Set up the fuzzy optimize models which regard reducing the loads fluctuation as the goal function,and regard assigned form of pick and blade, rotational speed of cutting drum,swing speed of rocker arm as designed variable,and optimized the parameters using corresponding optimize functiong in MTALBA's optimizationg toolbox.
