| This text chooses lift noise control work of the high residential building of Haichang happy city of Dalian as actual research object on the foundation of studying the rotatory machinery encourages making the flexible structure noise, it abstracts the model of calculation accords with the real structure of project and general significance. From analyzing and calculating the most basic influence factors of radiation sound of shadow structures as the rigidity , damping , quality of the computational structure ,etc. , find out the law of impact on power of radiation sound of the structure of every influence factor, and prove through the actual project, thus the further identifies the dependability and validity of the theory result. |
