homogeneous excitation meaning in Chinese
均匀激发
Examples
- A rectangular box simulating the axial box of the lathe tool is manufactured ; experimental measurements of the surface vibration on the rectangular box and the acoustic field around the rectangular box corresponding to firstly a series of a homogeneous excitation and secondly two iii independent white noise excitations are taken in a semi - anechoic chamber . taking the vibratory properties as input , the properties of the sound field are calculated by the evsbpm and the sdsbpm respectively . the effectiveness and reliability of the evsbpm and the sdsbpm for the calculation of acoustic radiation problem is further verified from the comparison of the calculated results and measured ones
第五章设计加工了一模拟机床主轴箱的长方箱体，在半消声室环境下，分别对其在单点处一系列简谐激励作用下和两点处的独立白噪声激励作用下的振动及其辐射声场进行了实验研究和分析计算，通过计算结果和实测值之间的比较，进一步验证了改进体积源边界合肥工业大学搏士学位论文点方法和统计分布源边界点方法计算振动声辐射问题的有效性和可靠性。
