동하중과 정하중의 관계

2018-04-20View Original

Thread Content

장비의 동하중 계수를 확인할 때마다 항상 동하중 계수가 1 미만으로 보지 않았습니다. 그리고 일부 엑셀 표에서 수압 동하중을 계산하는 공식을 보면, 동하중 공식은 정하중에 다른 계산식을 더한 구조입니다. 따라서 동하중이 계산된 결과에서 이미 정하중이 포함되어 있는 것일까요? 장비 지지구조는 계算出来的动荷载就行了,而不是说要承受动荷载+加上静荷载? 例如:球磨机4吨,查表动荷载系数为5.5,那么动荷载就是2吨(5×4=2),对设备支架的要求是承受4.吨还是还是4.5吨?(结构计算中的安全系数不考虑,结构专业会考虑)
