Application of Stress Testing Combined with Non-Destructive Testing in Safety Assessment of Crane Metal Structures
The crane is an indispensable mechanical equipment in modern industry,which is widely used in various industries.The metal structure is the skeleton of the crane,bearing and transferring the various loads on the crane,its working state directly affects the working performance,safety and reliability of the whole machine,once the failure will bring huge direct and indirect losses.Therefore,it is very important to carry out the necessary detection and analysis of the metal structure to further evaluate whether the crane performance is safe and reliable.In the safety assessment of crane metal,the most common is stress testing and non-destructive testing.Stress testing can assess the stress condition of the metal structure of the equipment,and non-destructive testing can find the defects of the weld and the base material,so as to objectively and accurately evaluate the safety performance of the metal structure of the crane.Based on this,the working principle of stress testing and non-destructive testing and its application in the safety evaluation of crane metal structure are briefly analyzed,in order to better ensure the safety and reliability of crane construction.
