结构破损 meaning in English
structural failure
Examples
- In this thesis , an improved bp algorithms based on genetic algorithm ( ga ) - bp neural network combined technology has been proposed to solve the two problems mentioned above
针对bp网络的不足，本文提出了一种基于遗传算法( ga ) - bp网络的混合技术进行结构破损诊断的方法。 - Many structure damage detection methods have been developed based on atime - invariantdynamical systemthatisassumethestructuralphysicalparameters ( such as stiffness , damping coefficients ) are time - invariant
基于时不变系统已经提出了许多结构破损诊断的方法,认为结构参数不随时间改变。 - Three numerical simulations have showed that the gabp has a better stability , precision and robustness than the traditional bp neural network , and is the reliable and accurate methods in structural damage detection
对比遗传bp网络与传统bp网络对三个仿真算例的识别结果，遗传bp网络的稳定性更好，精度更高，对噪声有很强的鲁棒性，是一种准确有效的结构破损诊断方法。 - However , in fact , thephysical parameters and dynamical character of the structure duringthe occurrence ofdamage are time - varying , and the response signalbehaves a non - stationary character . thus , it is generally recognized that the linear time - varying ( ltv ) model is moreappropriate and better than linear time - invariant ( lti ) model to capture theinstantaneous dynamical behaviors
然而事实上,结构的损伤使得其物理参数和动态特性随着时间而变化,结构的响应具有非稳态的特征。因此,利用线性时变系统模型,获取系统的时变特征,才更有利于结构破损诊断,线性时变系统的参数识别也受到了越来越多的关注。 - Through the investigation research on practical damaged element , considering the effect of corrosion , high temperature , wet environment , damage ( crack ) on structural durability , bearing capacity . this paper established the reliability analysis method of large - scale industrial factory , and applied the fuzzy mathematics to establish the factor set and weight coefficient set on the basis of expert experience . an analyzed method for fuzzy evaluation of structural element and bent frame structure system reliability is put forward
