基于等效原则、相似理论,考虑三维地震动作用下振动台试验中原型结构隔震层的简化,并对模型结构隔震层进行系统研究。针对不同高宽比隔震结构,提出完全等效简化方法和部分等效简化方法,包括隔震垫等效、模型支座参数及坐标确定、相似关系确定等。利用不同高宽比隔震结构振动台试验,结合有限元数值模拟,进行方法验证。理论推导与数值模拟证明简化方法具有良好的准确性,且在误差允许范围内,简化后的隔震层所获得的加速度、速度、位移等动力特性与简化前相同,可以用于振动台试验模型设计。 相似文献

2021 年新修订《种子法》虽然确立了实质性派生品种制度,但缺乏本土化配套制度建构。规范系统上应以《国际植物新品种保护公约》和相关域外立法例为体,从本土制度汲取营养以为用。研究发现:实质性派生品种与演绎作品都是处理创造与衍生创造关系的实例制度,具有较高的法律关系相似度。通过借鉴我国《著作权法》中的演绎作品制度,可以建构适用于我国实质性派生品种的制度模式。对经济作物与粮食作物分别设置双重许可制度和法定许可制度并实施收益共享机制,以此构建出我国实质性派生品种的本土化制度。 相似文献

基于QFD和TRIZ集成的油辣椒灌装机创新设计 总被引:2,自引:0,他引:2
针对概念设计阶段质量功能展开(QFD)与发明问题的解决理论(TRIZ)作用特点的不同,提出了一种集成QFD与TRIZ理论的产品创新模型。首先运用QFD的质量屋分析用户需求,确定设计冲突,然后结合TRIZ理论进行描述,得出问题的解决方案,并对模型中多目标问题的求解做了一定的改进研究。最后将该模型用于油辣椒灌装机的创新设计,较好地解决了普通灌装机存在的不足,验证了模型对设计过程指导的有效性。 相似文献

Aimed at the limitations of total fluctuating wind-induced response with combination of background and resonant components using Square Root of the Sum of Squares (SRSS) method, the theoretical combination formulas of fluctuating wind-induced responses and ESWLs are derived based on structural dynamics and random vibration theory. Meanwhile, the refined analysis method is firstly presented by four components formula to compensate the coupling component between background and resonant modes. The proposed procedure avoids the integration process of calculating elastic restoring force and completely considers the modal coupling effects, which can be used to calculate the ESWL for any complex structures. Taking the steel grid roof structure of a large museum as an example, the new method was used to calculate its wind-induced response. Compared with results of complete quadratic combination (CQC), the effectiveness and accuracy of the present approach has been revealed. 相似文献

在总结分析了几种常用综合评价方法的基础上, 提出了一种反映观察值与理论值之间相似性的新算法--符合度。该算法就评价信息个体(观察值)与标准值(期望值)的马氏距离, 再由马氏距离转化为评价对象与标准的接近程度, 即符合度(r)。首先进行指标数(p)、相似度(r)与马氏距离(d)的模拟试验, 再通过曲面拟合的方法找出它们之间的关系模型。通过大量抽样试验, 验证符合度的次数分布与原先设定的符合度的良好对应关系, 说明模型的可行性与可靠性。以小麦RVA性状为指标, 利用该算法分析扬麦系统若干品种之间的接近程度, 并评价多变数复杂效应回归分析模拟试验的结果。符合度算法不需要数据标准化处理, 直接利用原始数据, 减少了计算工作量, 降低了因数据标准化处理方法不同而引起的评价结果差异, 同时由于不需要赋权, 排除了主观性的影响, 保证了信息的完整性以及评价结果的可靠性。 相似文献

Thermal performance of the green roof is an important basis for energy-efficient design and evaluation. However, the current studies on the thermal performance of the green roof seldom involve thermal inertia of the green roof. Based on a long-term experiment of an extensive green roof in natural ventilation state and a five-month ongoing measured data in summer, thermal inertia of the extensive green roof was studied by statistical analysis method. The results show that thermal decay to outdoor climate effect through green roof was increased by more than 100% and delay time of thermal response to outdoor climate on internal surface of the green roof was reduced in comparison with that of the bare roof. 相似文献

利用2017年7月28日—2018年9月18日青海省海北牧试站架设的DZN2型自动土壤水分观测仪与人工烘干法平行对比观测土壤水分资料数据,通过对比差值、计算差值概率等相关统计方法,对10~50 cm土壤质量含水率进行逐层分析。结果表明:在研究时段内,海北牧试站自动与人工观测取得的数据随时间的变化趋势基本一致。自动站观测的土壤质量含水率较人工观测值偏低,其中30~50 cm差值相对较小,10~20 cm差值相对较大。根据自动站与人工观测的数据对各层土壤质量含水率进行订正,绝对误差均小于3%,表明海北牧试站自动观测的土壤水分资料基本能代替人工观测,进而为推进农业气象的自动化监测提供一定的技术支撑和理论依据。 相似文献

An atypical dynamic phenomenon of mines, including its action forms and definition, were put forward, based on the mining accident at the Furong Mining Group Company in Sichuan, P. R. China. The mechanism of the atypical dynamic phenomenon was revealed by analyzing rock stress distribution, calculating the first and cycle broken distance of each thick and hard roof, and analyzing the balance structure of broken rock based on the three dimensional finite element software. The first stratum of the bent, sunken, aged strip was influenced by the geological conformation and the coal mining activity. This created the first break of the key stratum and led to the atypical dynamic phenomenon. We show that the key factors affecting the phenomena are the roof and floor structures, surrounding rock, and initial stress and rock burst tendency of the key stratum. 相似文献

A method for designing the auxiliary ventilation system for long
drivages with multiple fans spaced in series in long duels is proposed based on the criterion that no recirculation takes place between the air flowing in the duct line and the surrounding air, A recurrence method is also given to calculat the leakage and the resistance lose of the duct taking into account of the relationship among the pressure, resistance and the leakage of the duct. The calculating results show that the present method is belter than the other methods. 相似文献

On the basis of investigating wooden arch gallery bridges in China,perspectives of researchers studying wooden arch gallery bridges in northeast Fujian Province were reviewed,and the innovativeness of researches from the perspectives of cultural geography and significance of wooden arch gallery bridge for the locals’behaviors was proposed.Youxi Village in Qinyang Town,Shouning County,known as the Village of Gallery Bridge,was taken for example to analyze physical,spiritual and social properties of its wooden arch gallery bridge spaces.Wooden arch gallery bridge is an effective boundary point of settlement space,constituting natural ecological spaces and man-made physical spaces of rural settlements.And as a type of building space,wooden arch gallery bridge expands settlement spaces,contributes to settlement cultures,and enriches spiritual connotations of regional cultures.In northeast Fujian,wooden arch gallery bridge is an important social space for the locals’daily life by carrying on living,production and spiritual functions. 相似文献
