Dynamic reliability under Littlewood-Paley wavelet is the biggest, dynamic reliability under modified meyerwavelet and harmonic wavelet are close. Analyzing the dynamic reliability of structure under odd exponent wavelet is very simple, it doesnt calculate Power Spectral Density function integral, it is only to calculate the square of displacement standard deviation and the square of velocity, then the dynamic reliability of structure can be concluded by max distribution. In addition the effects of upper limit is considered, when upper limit is smaller, the dynamic reliability of structure is less, that is, the damage possibility is bigger.
通过结构地震反应在小波基下的动力可靠性分析说明:无论是单自由度还是多自由度从理论上推导在这四种小波下的结构动力可靠性是可行的,而且考虑的结构地震反应都是非平稳的高斯过程,方法实现也比较容易;在Littlewood—Paley小波基下求得的结构的动力可靠度比较大,由改造的meyer小波和谐波小波求得的动力可靠度略有差异;单边指数小波下的结构动力可靠性分析非常简单,不用求功率谱函数来积分,只需求得结构地震反应的位移方差,速度方差,利用最大值分布公式就可得到结构的动力可靠时程;另外也考虑了超越界限对结构动力可靠度的影响,超越界限越小,结构的动力可靠度越小,即破坏概率越大。

Initially, assuming that the contact between cam and tappet is"dry contart", a dynamics model of Hertzin contact stiffness and impact damping is established. Next, with dynamic load on cam—tappet pair from the model, an analysis is made both to unsteady EHD oil film in cam—tappet pair under condition of full and partial lubrtication and to wear characteristics of cam profile. then, according to the fact that the lubrication in cam—tappet contact surface is EHD lubrication, taking the interaction between stiffness and damping of unsteady EHD oil film and rigidity of solid object contact into account, a dynamics equation of valve train relating to the dynamic effect of EHD oil film is built up and solved. Consequently, a further study is made on the dynamic characteristics of valve train under interaction of EHD oil film dynamic behavior and the problem of EHD lubrication in cam—tappet pair. Finally, the dynamic effect of full and partial EHD oil film is studied accordingly.
