Artillery Buffer Design On The New Material Metal Rubber

This thesis is mainly research and develops a new type of artillery buffer using metal rubber, this buffer is mainly used for35mm antiaircraft guns to reduce its recoil force. Using the classical interior ballistics, this thesis establishes the interior ballistic equation, and establishes the dynamic analysis model through analyzing the force of the artillery, analyzes the model on the aspect of impulse and energy in the recoil and counter-recoil stage, illustrates the working process of the buffer in principle.According to the design requirements, the thesis develops the structure of the artillery buffer, using the metal rubber with good damping characteristics as main damping element and the annular spring with efficient buffer characteristics as main elastic components. Due to metal rubber and annular spring all have elastic and damping characteristics, the buffer has good damping capacity to reduce the recoil force in a great degree.In this thesis, the constitutive relation model of metal rubber is based on the theory of porous materials and dry friction damping; the interior ballistic equation and the annular spring parameters are calculated by using MATLAB software; buffer recoil motion curves are mapped out by using the ADAMS software simulate its performance, the curves mainly include recoil displacement-time curve, recoil velocity—time curve, recoil acceleration curve and the curve of the recoil force, etc. Simulation results show that the motion parameters of artillery buffer can meet the design requirements.
