Outline
In response to the high reliability requirements of missile-borne equipment in complex mechanical environments, a design method for vibration isolators based on high-manganese copper alloy is proposed. Firstly, a dynamic model of the missile-borne equipment was established, and the damping characteristics of the high-manganese copper alloy were thoroughly analyzed to determine its damping parameters. Subsequently, to balance the damping and strength properties of the vibration isolator, an optimization design model for the missile-borne equipment vibration isolator based on high-manganese copper alloy was constructed. The genetic algorithm was employed to optimize the relevant design parameters of the vibration isolator, resulting in an improved design scheme. Finite element analysis and mechanical testing demonstrates that, compared to traditional silicone rubber vibration isolators, the deformation of the high-manganese copper alloy-based vibration isolator was reduced by 40%, while its damping characteristics still met the vibration isolation requirements of the missile-borne equipment. This fully proves the superiority and rationality of the proposed design scheme.
