Abstract

Stanowisko posiada stelaż (2) z kształtowników stalowych, zawierający poziomą sztywną ramę wsporczą (3), na której są zamocowane pionowe elementy wsporcze w postaci sztywnych słupów nośnych (4), podstawki (5) oraz elastycznego wspornika przedniego (6) i wspornika tylnego (7). Na słupach nośnych (4) jest zamocowany sztywno silnik napędowy (8) swą płytą mocującą (9), który jest połączony z jednej strony elastycznym łącznikiem (10) z prądnicą tachometryczną (11) osadzoną na wsporniku przednim (6), zaś po przeciwnej stronie silnik napędowy (8) jest połączony sztywno swym wałem napędowym (12) z badanym tłumikiem, a za tłumikiem poprzez sprzęgło (13) z czujnikiem (14) drgań skrętnych, który z kolei jest osadzony sztywno na podstawce (5) wspartej na wsporniku tylnym (7) stelaża (2). Stanowisko jest przystosowane do sporządzania charakterystyk w zakresie częstości wymuszeń od 25 do 300 Hz.The stand has a frame (2) made of steel sections, containing a horizontal rigid support frame (3), on which vertical support elements are mounted in the form of rigid support columns (4), bases (5) and a flexible front bracket (6) and rear bracket ( 7). The drive motor (8) is rigidly mounted on the supporting columns (8) with its mounting plate (9), which is connected on one side with a flexible connector (10) to the tachometric generator (11) mounted on the front bracket (6), and on the opposite side the drive motor (8) is rigidly connected with its propeller shaft (12) to the tested muffler, and behind the muffler through the clutch (13) with the sensor (14) of torsional vibration, which in turn is rigidly mounted on the base (5) supported on the rear bracket ( 7) frame (2). The stand is adapted to prepare characteristics in the frequency range of excitation from 25 to 300 Hz.
