It is necessity to take an impact test for FOPS in laboratory in order to install falling object protective structures at engineering vehicle and check its dependability.

为了对工程车辆的落物保护装置进行可靠性试验提供理论依据，采用冲击动力学的塑性波两侧的动量平衡理论对工程车辆FOPS受冲击时落锤的动态响应进行了研究，建立了锤头变形的基本方程，绘制了方程相应曲线；建立了锤头在冲击过程中任一瞬时变形长度和非变形长度的数学模型，找到了工程应变和冲击速度之间的曲线对于塑性大变形的突变点及影响落锤变形的各个因素和控制变形的依据。

This problem is that research rolling over and falling objects protective structure of bulldozer by learning research condition of rops / fops and relative lay down international standard .

Methods:(1) Dissoluble PGN and CpG DNA were immobilized onto the surface of biotin cuvette for establishing target. Another effective tracking approach was established by immobilizing Escherichia lipid A F583 onto the surface of Non-derivatised cuvett. The biosensor technology was applied to screen anti-inflammatory TCM targeting on three key molecules.(2) The active compositions were isolated by AB-8 macroreticular resin from lycium bark. After the activities of compositions were evaluated, the most effective compositions was confirmed. In vitro, the affinities of different concentrations composition E binding with PGN, CpG DNA and lipid A were measured separately. The effect of composition E on vigor of RAW264.7 cells were tested by MTT and CCK-8, and its inhibition on TNF-α, which was released from RAW264.7 cells induced by PGN, CpG DNA and LPS, was also tested by ELISA. In vivo, murine sepsis models were made by intravenously heat-killed E.coli and heat-killed S.aureus, then protection of composition E on mice sepsis model were observed.

(1)将PGN及CpG DNA包被于生物素样品池，将lipid A包被于非衍生样品池，分别建立以PGN、CpG DNA及lipid A为靶点的技术平台，对114种抗炎中药水提物进行筛选、评价其活性物质含量，并评估出针对上述三种病原分子均具有较高结合活性的中药；(2)利用生物传感器跟踪检测技术、大孔吸附树脂分离技术，从地骨皮中定向分离与PGN、CpG DNA及lipid A均具有较高亲和力的活性组分；在体外实验中，测定不同浓度活性组分与PGN、CpG DNA及lipid A亲和力；MTT法及CCK-8法检测活性组分对RAW264.7细胞活力的影响；ELISA法检测活性组分对PGN(2μg/ml)、CpG DNA(10μg/ml)及LPS(100ng/ml)刺激小鼠RAW264.7细胞分泌TNF-α的抑制作用；在体内实验中，采用尾静脉注射致死剂量热灭活大肠杆菌和热灭活金黄色葡萄球菌，建立细菌脓毒症小鼠模型，观察活性组分对脓毒症模型小鼠的保护作用。
