First of all, the paper carried out test study on four two - spanned model members of fsmrcwb, including three 1 / 2 - scaled two - storeyed models and one 1 / 3 - scaled three - storeyed model. the study considered such factors as span ratio - l1 / l2, height - span ratio - hb / l of the beam, and cavity etc. the paper analyzed the test results, including analysis on mechanical property of the composite wall beam under vertical loads, and failure mode, deformation capacity, aseismic performance under horizontal loads and constant vertical loads
首先，進行了三個兩跨兩層和一個兩跨三層的框支密肋復合墻梁的模型試件試驗研究，主要內容包括：框支密肋復合墻梁在豎向荷載作用下的受力性能，在豎向荷載與水平低周反復荷載共同作用下的受力性能、變形性能、滯回性能和破壞形態，並將框支密肋復合墻梁試驗與框支砌體墻梁試驗進行對比分析。 -
With the help of this program, this paper does research on the moved backwards of the slide surface, lengthening the anchor section, the soil nail ' s total force, gets conclusion about relations between the soil nail ' s length and the slope ' s grade, height, soil ' s mechanical parameter ; relations between soil nail ' s total force and coulomb soil pressure. with the help of the large multiuse finite element program ansys, this paper analyzes the soil nailing in one - step ' s slopes, in two - steps " slopes, puts the emphasis on the axis force ' s distributing along the soil nail at each rows, the effect of both the excavating mode and the original slope figure to the axis force of the soil nail, the one another effect between the upper - step slope and the nether - step slope in the soil nail ' s axis force, gets conclusion about the design of soil nail at the first low, different slope body is the same with different excavating mode, the original slope figure has more effect to some than others because of the slope body, the reasonably design of the step width in two - steps slopes, the two - steps excavating and retaining has more virtue than the one - step ' s. through soil pressure analysis this paper does research on the differences and the links between the coulomb soil pressure theory and the rankin ' s, the vertical pressure at the slope surface when the slope surface is inclined and the retaining wall is rough, the soil pressure ' s distributing behind the panel, gets conclusion about the effect of both the slope body inner stability and the slope surface local stability to the soil pressure
通過分析比較，論證了對數螺旋線型比圓弧形作為邊坡的假設滑裂面具有較多的工程優點，並為此編制了一個採用極限平衡法分析土釘支護的fortran語言程序，以此作工具對滑裂面的后移、土釘錨固段的超長、土釘總力的大小等方面作了研究，得出了有關土釘的長度與邊坡的坡角、坡高、土體力學參數的關系、土釘總力與庫侖土壓力間的關系等結論；採用大型通用有限元數值分析程序ansys分別對採用土釘支護的一階邊坡、二階邊坡進行分析，重點是研究各排土釘的軸力分佈規律、開挖方式及原始邊坡形態對土釘的軸力的影響、上下階邊坡在土釘軸力方面的相互作用，得出了有關第一排土釘的設計問題、不同類型的土體應適用於特定的開挖方式、原始開挖出的邊坡形態對一些類型坡體的邊坡土釘支護有較大的影響而對另外一些影響不大、二階邊坡臺階寬度的合理確定、二階開挖及支護比一階時具有較多的工程優點等結論；通過土壓力分析對朗肯、庫侖兩種經典土壓力理論的區別與聯系、坡面傾斜及墻背有摩擦時的坡面豎向應力分佈、面板背土壓力的分佈形態作了研究，得出了邊坡支擋土壓力受坡體內部穩定與坡面局部穩定兩個方面的影響、土釘支護面板背土體中卸荷拱的存在對面板受力有利等結論。 -
Fourth, the monitor and fault diagnosis of vehicle transmission system s vibration signal is researched. the mode testing and analysis of automobile s transmission system is achieved in the first step. the vibration amplitude testing and analysis on vertical direction about even, parts of automobile s transmission system is achieved then. the next testing and analysis of automobile s transmission system is considering the effect of different elasticity of absorber. at last item of this part, the dynamic intensity testing and analysis of automobile s transmission system is achieved. considering various affect factor. the conclusion is educed by synthesized analysis
第四，對車輛傳動系的振動信號進行了檢測分析與故障診斷。首先對汽車傳動系進行了模態測試與分析，然後對汽車傳動系各部分在垂直方向上的相對振動幅值進行了測試與分析。根據上述測試分析並綜合其它因素得出了結論。
