导出了VWWJ—19/7.8型无基础无油润滑空气压缩机的振动力学模型,进行了程序计算和振动测试。结果表明,机器的减振性能良好,计算与实测结果相近。文中所述理论和方法亦适用于其它动力机械的减振设计计算。
The vibration model of VWWJ-19 / 7.8 non-oil-free air compressor has been derived, and the program calculation and vibration test have been carried out. The results show that the vibration damping performance of the machine is good, the calculation and the measured results are similar. The theories and methods described in this paper are also applicable to the design of vibration reduction of other power machinery.
