shafting system The various components of large industrial fan impellers, such as kiln I.D. fans for the cement industry, have natural resonant frequencies. If excited during operation, these natural resonant frequencies may cause vibratory stress and fatigue, resulting in the cracking or destruction of certain components. Fortunately, simple field tests performed with fairly inexpensive equipment can measure the vibration response of the various components and anticipate frequencies that will be excited in the field installation. This article describes one such test, the impact (or impulse) excitation technique, which has several advantages over the swept-sine wave excitation test. Further, the article recommends ...... Matching a shaft flex to your swing characteristics is the most important consideration when selecting a set of clubs. Clubmaker.com now provides a unique dynamic fitting program that allows our customers to be fitted exactly for optimum shaft flex for shot accuracy, distance and feel, for their club sets or for new custom clubmaker.com club sets.
