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。Based on extensive investigation of construction technique history of chinese ancient buildings, the structure method, structure developing history and seismic behavior of chinese ancient timber structure buildings are analyzed in several respects of the structural system and form. through a series of experiments on constituent parts of chinese ancient timber building structure, including the tests on the corbels and brackets called dougong subjected to low cyclic reversed loadings, the tests on the wooden frame using the tenon - mortise joints as connections of column and beam subjected to low cyclic reversed loadings, the tests on vibration isolation effect of friction and slippage between column footing and their socle base, and a series of shaking table tests on a chinese ancient timber structure palace building mode under artificial earthquake at serving conditions, destroyed conditions and reinforced conditions, many valuable results of structures such as moment - curvature hysteretic loops of dougong structure and tenon - mortise joints under low cyckc reversed loadings, the static function, the seismic performance, energy dissipation, vibration reduction, energy - loss mechanism, nechanicalmode and failure mode were studied. aplenty of valuable parameters of the structure system were obtained, such as the natural period of structure, vibration modes, damping ratio, factor of vibration isolation, oscillate amplitude of ineitial accebration, velocity and displacement, magnitude of slippage, and the mechanism of structure failure and collapse etc. based on these research, the complete analysis of ancient timber structure under earthquake were carried out in which including mechanism analysis method, calculating mode, strength analysis of members and joints, strengthening methods for serving damaged ancient timber structure buildings were also taken into account
