Abstract


35mm grenade launcher , grenade launcher research status and development trend analysis of the papers studied composition and technical features of the structure of the transmitter , and the following research : the use of weapons and gas dynamics transmitter and classical interior ballistic theory bore and a mathematical model of the gas chamber pressure , written in Visual Basic software calculated the bore and the gas chamber gas pressure variation . Based on the theory of multi-body system dynamics and virtual prototyping technology , dynamic simulation model using ADAMS software to establish a grenade launcher , the analysis of the law of motion of the emitter automata, barrel and Barrel parts and shooting recoil , key research the main parameters change weapon performance law provides a theoretical guidance for the grenade launcher design and performance improvements . ABAQUS software based on finite element theory , the dynamic stress analysis of the locking mechanism of the grenade launcher , the results show the strength of the locking mechanism is sufficient to meet the job requirements . Grenade launchers and other weapons wound cavity experimental study, the use of X-ray shot wound cavity images ; based on image processing technology, using MATLAB software experimental picture image enhancement , edge detection and three-dimensional reconstruction of the cavity , and the preparation of the parameters of the cavity volume and cross-sectional area calculation software . This thesis provides an effective and feasible approach for the detection of traumatic cavity .
