- Graphite ) and the special viscoelasticity of polymer , interlayer exfoliation of the filler and its nanocompounding with polymers can be realized in the shearing force field of pan - milling , through the effects such as deformation , dislocation , tension - sliding and shearing exfoliation of graphite , the tension - thinning , pulverization of pp , as well as the imbedding , mixing and dispersion of graphite flakes in pp powder etc . the results show that the interlayer exfoliation of graphite and nano - compounding with pp proceeded stepwise , caused by a combination of friction , squeezing , stretching , and shearing in three - dimension during pan - milling
石墨片层的受限空间影响i一pp / yep25o复合材料中pp结晶行为，进入石墨片层间的pp分子一部分择优取向，形成沿( 040 )晶面法线方向择优生长的a一晶，另一部分相对分子质量较小、运动活性较高的pp分子则受到石墨片层的挤压和限制而转化为y -晶，在i一pp厅ep250复合材料中， y -晶相对含童达34 . 8 % 。 - Presents the model proposed for analyzing the vibration characteristics of shrouded blades and their calculation method by employing a wave propagation theory and modal synthesis technology coupled with a finite element method from the view point it is possible not only to conduct frequency modulation of the shrouded blades of a gas turbine , but also to utilize the friction effects between them to dissipate energy , thereby attaining the aim of vibration alleviation , as shrouded blades have been widely used in the design of high - speed turbomachinery , such as modern gas turbines and steam turbines , and with the shrouded blades forming an integral whole in a centrifugal force field , the vibration characteristics of the whole ring of blades are different from those of a single isolated blade , and this makes it essential to take into account the integral effect of blade shrouds , concludes from the calculation examples and engineering application that the above approach is valid and correct along with the possibility of considerably reducing the scale of calculation and analysis , and points out it is necessary to take into consideration the coupled effect of the whole ring of blades while the dynamic characteristics of shrouded blades is being analysed
带冠叶片不但能调频，还可以利用叶冠之间的摩擦效应来耗散能量，达到减振的目的.带冠叶片在离心力场中形成一整体，其整圈叶片振动特性不同于单个孤立叶片，需考虑叶冠的整体效应.利用带冠叶片系统的循环对称性，提出了采用波传播理论和模态综合技术，结合有限元方法研究燃气轮机带冠叶片振动特性的分析模型和计算方法.算例和工程应用证明了该方法是效性的、正确的，并可以大大降低计算分析规模.研究表明带冠叶片动力特性分析时必须考虑整圈叶片的耦合效应 - In this article , a program about the weighted residual method is compiled by using matlab mathematics software to solve this problem . the program has broad applicability , which can analyze the displacement fields and the internal force fields of moderate - thick plates on two - parameter elastic foundation with arbitrary boundary and arbitrary loading con - ditions ( contains uniform line load , concentrated load or combined loads on arbitrary position of plates )
