СПОСОБ УСТАНОВКИ ЗАДАННОГО РАССОГЛАСОВАНИЯ НА ЛОПАСТНОМ КОЛЕСЕ ТУРБОМАШИНЫ, ЛОПАСТНОЕ КОЛЕСО ТУРБОМАШИНЫ С ЗАДАННЫМ РАССОГЛАСОВАНИЕМ |
| 摘要 |
The method involves determining an optimal value of standard deviation of frequency variation with respect to a maximum amplitude response of desired vibration on wheel according to operating conditions of the wheel inside a turbine engine. Blades having different natural frequencies are arranged on the wheel such that frequency distribution of the blades has a standard deviation equal to a value of variation determined statistically. An independent claim is also included for an impeller wheel having blades. |
