Optimized Design For Braking Mechanism Of Individual Balance Projectile System

The mechanism of balance projectile is to make μse of the equilibrium body with equal quality of the pill come to equilibrium the pill to project the momentum,and the blast-off system of the piston(optimize before be called the piston parts,optimize behind be called the piston) braking of the braking mechanism that pμsh the pill and equilibrium body. The braking mechanism is key mechanism to carry out the piston braking. therefore, the design rationality of its structure has the direct influence towards shooting the function. This text turns the design towards piston parts and distortion ring of the braking mechanism to carry on optimize, and make μse of the software of ANSYS/ LS- DYNA not the line dynamics analysis function, turn to analysis that imitate in front and back, and carried on the on trial research. The main contents of the thesis include:The braking mechanism of balance projectile, the motive reaches of work principle and made process to carry on a description.Make μse of ANSYS/LS-DYNA software carried on to imitate true dynamics analysis towards making motive to reach medium parts while real load, physical quantity understood to make parts in the process, the design of the analytical piston parts shortage of place, and aim at shortage of the place carried on optimization design.To optimization behind of braking mechanism to carry on dynamics to imitate true analysis,.The change course of physical quantity such as the stress, strain, axial force, energy dissipation and acceleration etc is given. relatively analyzed different material to distortion ring absorbing of ability effect, and the optimization absorb ability effect better material.Has been analyzed make physics within process quantity, optimization behind of braking mechanism to reach to pound at energy to descend 35.7%, the biggest axialforce to descend 50.3%, carried out to lower to the biggestly axial force of braking mechanism passed to experiment a result to also verify to make motive to reach excellently to turn a design further of possibility and rationality.
