中文摘要：
虽然研究振动和噪声的传递系统模型和传递路径的贡献度具有重要意义,但是目前还很难清晰正确地阐明多维路径的贡献量。基于动态灵敏度的技术,解决了振动传递路径的参数贡献度问题。采用路径的灵敏度作为度量准则,提出振动传递路径的参数贡献度的有效途径,给出理想的数值分析结果,清晰地阐明了时域内振动传递路径的参数贡献度。
英文摘要：
It is significant that the system models and contribution rank of transfer paths for vibration and noise problems are researched, but it is very difficulty that the contribution rank of transfer paths are syllabify and accurately clarified at present. Based on sensitivity technique, the problem for parameter contribution rank of vibration transfer paths is solved. The sensitivity is employed as measurement criterion, and the effective approach for parameter contribution rank of vibration transfer paths is presented. The ideal numerical results are obtained. The parameter contribution rank of contributions among multiple and/or multi-dimensional paths is interpreted correctly and expressly in time domain.
