Typical Materials Abrasion Rules and Failure Lives Prediction of Key Parts for Breech Mechanism Based on Virtual Prototype
As a kind of complicated mechanical automation,most of key parts of breech mechanism are cams delivering forces and movements by parts outline and figure.The major fault mode of breech mechanism is grain abrasion caused by dry sliding friction.There are no feasible and practical technologies to simulate and predict the abrasion failure lives of key parts for breech mechanism.A new simulation and prediction method is firstly put forward in this paper.Based on Pro/E and ADAMS,the virtual prototype of breech mechanism of semiautomatic vertical sliding-wedge type is established.Key parts load spectrum can be obtained based on virtual prototype.Pin-on-disc friction and abrasion testing machine is designed and adopted to obtain typical materials abrasion rules.Finial simulation and prediction results are given as abrasion thresholds and operating items,which provide sufficient references for breech mechanisms design and safeguard.
