비교샘- 베어링 진동과 기계적이완(looseness)진동 (진동측정 진동분석 진동교육)

진동 주파수 분석방법에서 사용되는 차수분석에는 다양한 진동원인들에 대한 회전수 대비 그 근거를 제공할 많은 규칙들이 있다. 특히 차수(order)의 동기요소의 대표적인 느슨함(이완;looseness) 신호와 비동기요소인 구름베어링의 결함진동을 서로 비교하는 것은 차수분석의 하이라이트라고도 할 수 있다. 이 두가지를 구분할 수 있는 방법...

어링의 결함진전과 진동기법 (진동 스펙트럼으로 베어링의 결함수준을 판별하는 방법)

-----------------------------------------------------------------------------------------------------------------

구름, 볼 베어링은 회전하는 축의 하중을 받아서 지지대에 전달하는 중간 부품이다. 그래서 회전부분과 고정부분의 잇는 매개체로서의 중요한 구실을 한다. 물론 진동도 이 곳을 통해서 전달된다.

기본적으로 구름베어링에는 구름체(전동체, 볼, 롤러)와 레이스(외륜, 내륜, 케이지) 간의 점 접촉 면적을 줄여주기 위해서 윤활이 반드시 필요하며, 그리고 충격음이 반드시 존재한다. 또한 구름, 볼 베어링은 계속적인 마찰로 인해 마모상태가 진전될 경우, 더 이상 구름지지요소로서의 구실을 못하게 되므로 이를 미리 예상하고 방지하는 것이 설비관리자의 주요임무중의 하나라고 할 수 있다.https://contents.premium.naver.com/bisope/visope/contents/230925101017823pd

지진은 지반의 진동입니다.

지진에 대해서 우리는 생각보다 많은 학습을 해왔습니다. 그 중에서도 ‘P파(종방향, 수직의미)와 S파 (횡방향, 수평의미)’ 그리고 ‘진도 7’ 등 용어로 생각보다 많이 알고 있으시구요. 또 ‘공진’ 같은 진동용어도 전문가처럼 이미 알고 있습니다.

사람은 기본적으로 직립 보행하는 동물입니다. 짜증스러운 진동에 대해서는 수직방향으로 움직이는 흔들림에 민감하며 초당, 특히 4~8Hz정도도 흔들리는 것을 아주 싫어합니다. 또한..https://contents.premium.naver.com/bisope/visope/contents/240419063447848qm

BISOPE series 59 Two measurements and methods for vibration evaluation


BISOPE series 59- Two measurements and methods for vibration evaluation

-------------------------------------------------------------------------------------------------------------

When measuring the vibration of an object (test object, mechanical structure, building, etc.) and trying to quantify and evaluate its size, we are asked that it is difficult because the evaluation unit required by the vibration standard and the output unit output from the vibration sensor are not the same. . For example, according to the management manual provided by the machine manufacturer and construction company for evaluation, it is said to evaluate in terms of displacement. However, if the measurement sensor currently being measured is an acceleration sensor, is it possible to obtain it by converting to displacement (simply integrating twice)? This is about ? What should I do right?


97 진동평가를 위한 측정 및 방법 두가지


-----------------------------------------------------------------------------------------------------------------

어떠한 대상(시험체, 기계 구조, 건물 등)의 진동을 측정하여 그 크기를 정량화하여 평가하려고 할때 진동기준에서 요구하는 평가단위와 진동센서에서 출력하는 출력단위가 같지 않아서 어려움을 갖는다는 질문을 받는다. 예를 들어 평가를 하기 위해 기계의 제조사건설사를 통해 제공받은 관리 메뉴얼에 따르면 변위로 평가하라고 되어 있는데 현재 측정하고 있는 계측센서가 가속도센서일 경우 변위로 변환(단순히 두 번 적분)하여 구할 수 있는 것인지?에 대한내용이다. 어떻게 해야 맞는 것인가?





52 필드발란싱, 다이나믹 발란싱


필드발란싱, 다이나믹 발란싱

진동을 발생시키는 대표적인 힘으로는 ‘충격가진력’과 ‘원심불평형력’이 있는데 이 중에서 원심불평형(Imbalance)은 원심의 불평형력( F= mrw²)으로 작용하여 회전기계전체의 결함현상의 80%이상을 차지하는 매우 중요한 결함 원인이기도 하며, 다른 원인(축정렬불량, 베어링불량, 베어링조립불량 등)에 의해 파생되는 2차결과이기도 하다. 그런데 이러한 원심불평형력( 1X, 1Order)을 제거할 수 있을까?

진동분석에서 말하는 "회전시 Imbalance는 반드시 존재한다"는 의미는 "언발란스는 줄일 수는 있어도 없앨 수는 없다"는 말과 같다. 그래서 소위 ‘발란싱’이 필요한데 회전불평형력의 교정작업은 불평형력을 줄여주는 것으로서 발생면(Plane)에 따라 단면발란싱, Multi발란싱(Dynamic)으로 나눌 수 있고, 교정작업을 하는 장소로 구분해 본다면 필드발란싱과 삽(랩)발란싱으로 구분한다.
