| With the development of animal husbandry,the grass feed processing machinery was developed vigorously. The straw cutter is one of the widely used machines . But it has the problem of power consumption oversized at present. The design of the cutterhead plays a decisive role to the power consumption, mobile blade is the key part in the cutterhead.Therefore, it is especially important of designing performance cutterhead.In order to solve this problem,Take the 9Z-480 flywheel-type cutterhead as the prototype. Through to exproment analysis for cutting process of the cutterhead, infer the equation of cutter curve or logarithmic spiral equation. In order to make the design more accurate , program in computer software of Matlab, draw up different angle cutter curve according to the equation. Parameter modelling and simulate was took in the cutterhead of the prototype by software of 3-D. The way has more flexibility and effectiveness,reduces the development cycle of product . Different angle cutter curve mobile blades are designed and produced to being selected.A orthogonal test was Completed in the prototype . And analysis datas,obtain the mathematical model,which power consumption is the minimum. And optimization was carried in this model. Obtain optimization result,which provide powerful reference for series design and the production. |
