基于齿轮箱结构的试验模态测试研究

Study on the Modal Test Based on the Gearbox Structure

现代机器多要求高速、高效、低耗能、轻型、低噪声和性能可靠。解决这些问题,离不开动态测试与分析,因而模态测试技术得到迅速发展和广泛应用。目前的发展趋势是把有限元方法和试验模态分析技术结合起来。

In modem industry, all kinds of machines are developing towards the direction of high speed, high efficiency, light, low energy resuming, low voice and reliable performance. To meet these requirements, it can not get away from the dynamic state test and analysis, so the modal test technique is developed quickly and applied extensively. The current development trend is to put the finite element method and the modal test technique together.
