摘　　要：针对某钢厂冶金起重机吊车梁插板位置出现裂纹的问题,首先通过现场应变监测了解吊车梁各关键部位的应变状态,进而计算出各关键部位的应力水平。结合有限元计算结果,明确了吊车梁插板位置处裂纹出现的原因,为吊车梁维护策略的制订提供了决策依据,保证了冶金起重机的稳定和安全生产。Aiming at the problem of cracks in the insert plate of metallurgical crane beam,firstly,the strain state of each key part of crane beam is understood through on-site strain monitoring,and then the stress level of each key part is calculated.Combined with the finite element calculation results,the causes of cracks at the position of the insert plate of the crane beam are clarified,which provides a decision-making basis for the formulation of the maintenance strategy of the crane beam and ensures the stability and safe production of the metallurgical crane.
