Modeling and Simulating of Rigid-flexible Coupling Containing Clearance for an Assault Rifle Automatic Mechanism

DONG Xue-hua,WANG Ya-ping,XU Cheng (Nanjing University of Science and Technology,Nanjing 210094,Jiangsu,China)  
The kinematics/dynamics characteristics are its design key technologies.At present,the virtual prototype method used for simulation analysis is the most advanced and effective.A reasonable simulation model is particularly important.The automatic mechanism characteristics of an assault rifle can be accurately described by the rigid-flexible model containing clearance and considering variously actual factors.The model was founded by defining restriction,contact,lubrication and load among the parts of automatic mechanism on the ADAMS.The simulating results tally with the experiment results,testifying the model correctness,opening out the main parts kinematics/dynamics characteristics,providing a new method for designing firearms.
