- We can study the vibration characteristics of the flexible projecting beam and check the simulation data of the flexible projecting beam
然后对这些悬臂梁模型施加相同初始条件，选取粱上相同位置观测其振动位移和振动应变。 - The simulation data of the flexible projecting beam with different crack flaw is different . so we can build bp neutral - work to identify the position and the length of the crack in the flexible projecting beam by the simulation data . the input vector of bp neutral - work is the simulation data becomes , the training object is the position and the length of the mapping crack
Bp神经网络是一种多层的前馈型人工神经网络，可实现从输入到输出的任意非线性映射，所以选取bp神经网络可以有效地实现从观测信号到裂缝所处位置以及裂缝长度的非先行映射，以达到对柔性悬臂梁上裂缝缺陷的智能诊断。 - The physical flaw in the flexible structure will influence the stability of flexible structure . the flexible projecting beam is the typical flexible structure , and the crack is the common physical flaw . the dynamic analysis of the flexible projecting beam with crack is the represent of the study of the flexible structure with flaw
柔性悬臂梁是柔性结构中最常见的一种典型结构，裂缝则是柔性结构经常产生的一种物理缺陷，研究裂缝对柔性悬臂梁振动特性的影响，对研究物理缺陷对柔性结构稳定性的影响具有一定的代表性。 - Against classical dynamic balancers of crank and connecting rod mechanism , the test system has virtue hereinafter : ( 1 ) supporting structure adopt projecting beam uniquely . the signal of vibration provoked by crank and connecting rod mechanism revolving is concentrated to strain beam . the signal is not only abundance , but also easy to test and the test sensitivity is great
与传统的曲柄连杆机构动平衡机相比，这种测试系统具有以下优点：支承结构采用独特的悬臂梁式结构，曲柄连杆机构在运转过程中振动规律完全映射到支承梁的应变上，振动信号丰富且易测试、灵敏度高。 - We build some flexible projecting beam finite element modal with different crack . through studying vibration characteristics of different flexible projecting beam modal , what has different length crack on different position , we can research tie influence of the position of crack and the length of crack . then we make an experiment on the vibration of the flexible projecting beam
为了讨论裂缝所处位置、裂缝长度对柔性悬臂梁振动特性的影响，在梁上选取了7个不同位置，并在每个位置上设定了7种裂缝长度，建立了49根的柔性悬臂梁的有限元模型。
