危险断面
危险截面
Examples
- Through the test of the separating sieve ' s and beams vibration acceleration , the dynamic bending moment , torque and shearing force as well as the analyze of each parameter by dividing rotation speed range from 300 r / min to 600 r / min of the main shaft , the change regularity of the vibration of the separating sieve , the vibration and the dynamic load on dangerous cross section with the change of rotation speed of the main shaft is obtained . research shows that there exits apparent relevance between the vibration as well as the dynamic load of the main beam and the vibration of the separating sieve . the vibration of the separating sieve mainly affects the composition of low frequency of the vibratio n of the main beam , appropriately amending the vibration acceleration of the separating sieve , the loading and vibration of the mam beam can be directly improved
通过分档测试主轴转速在300 600r min范围内分离筛与梁的振动加速度、梁所承受的动态弯矩、扭矩和剪力以及各参量的时频域分析，得到了主轴转速与分离筛振动、主梁的振动及其危险截面的动态载荷间的变化规律，研究表明梁的振动和其所承受的动载与分离筛的振动之间具有明显的相关性，分离筛的振动主要影响梁振动的低频成分，适度改善分离筛的振动加速度，可直接改善梁的负载和振动特性。
