In the course of working, , the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly
與單向犁相比,其優點在於:耕地無開、閉壟,地表平整,降低了耕后整地的能量消耗,減少了地頭的空行程,因而大大提高班次生產率。為了滿足犁體梭式作業的要求,我們採用了一隻小容積雙作用的液壓油缸;同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗,我們發現:該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重;主犁梁和油缸缸體的連接部分(即油缸底座)突然發生了斷裂,造成整個犁體無法正常工作。First of all, i summarize the forecast model category and estimate each model in detail, then, i adopt different model to forecast demand, supply, bdi of bulk shipping market. as to demand forecast, i mainly focus on the imitating precision of primitive data, adopt grey forecast model, self - suited filter model separately, and then compose these models as a better one. as to supply forecast, i use econometrics model to describe the complicated relationship of demand, supply, bdi, gnp etc. as to bdi, i try to draw into market integrated factor, describe the relationship of bdi, supply, capacity, speed, rate of oil, navigating capital etc. then finally, i make afterwards evaluation of these models and then analyze future bulk shipping market in detail
