Extrusion Hole Test for Improving Fatigue Strength of the Chain Plate of Bucket Lift
Under the alternating load, the chain of high-speed heavy-duty bucket hoist passes through hundreds of thousands or more shocks, and the final failure mode is mainly chain plate fatigue fracture. There is no report on this kind of chain fatigue tester at home and abroad. Through force analysis of ch...

| description | Under the alternating load, the chain of high-speed heavy-duty bucket hoist passes through hundreds of thousands or more shocks, and the final failure mode is mainly chain plate fatigue fracture. There is no report on this kind of chain fatigue tester at home and abroad. Through force analysis of chain plate, theoretical basis is provided for elastic-plastic analysis after extrusion, analysis of residual stress, calculation of displacement under elastic-plastic state, and actual working condition test etc. Through the design of extruded-hole mandrel with different interference, statistical analysis is carried out on relevant data to further explore the range of interference of extruded holes, and tensile test is carried out on extruded-hole chain plate with certain interference to verify whether the tensile strength of chain plate will be affected. |
