| 摘 要： | 摘要：为研究驾驶室内噪声问题，本文采用球型阵列对拖拉机驾驶室内进行噪声源定位测试，从分析结果得到驾驶室内声源位置主要在门锁机构附近和操纵机构附近，且在车门玻璃处出现较大的反射噪声，运用声强探头对声源泄漏位置进行特定的声强测试，用来分析驾驶室内产生噪声源的具体原因，为下一步改善拖拉机驾驶室内的声学环境打下基础。

| Abstract: | In this paper, ABAQUS simulation software is used to establish the simulation model of rubber element of a certain type of highly flexible coupling. The axial force and axial displacement are analyzed in its working condition. The result of the simulation calculation is in accord with the calculation result by ＂Rivlin＂ theory. The method of simulation used in this paper will he helpful in the design of axial displacement compensation device for highly flexible couplings. |
