dc.description.abstract | Launch vehicles and satellites experience severe vibration and pyroshock loads during flight phases. In particular, intense pyroshock, which is generated by the actuation of separation devices, can cause malfunctions in the electronic components in launch vehicles and satellites, potentially resulting in catastrophic failure during flight. This paper introduces a new three-axis hybrid mesh isolator using the pseudoelasticity of a shape memory alloy wire that was manufactured and tested to attenuate pyroshock and vibration transmitted to the electronic components. To characterize the isolation capability, quasi-static loading tests were performed; the test results showed that the pseudoelastic effect of the shape memory alloy wire significantly absorbs energy due to the stress-induced phase transformation. The ground pyroshock test results showed a remarkable pyroshock load attenuation of the hybrid mesh isolator in all frequency ranges. The dynamic characteristics and vibration isolation performances of the mesh isolators were also verified by random vibration tests. The healthiness of the hybrid mesh isolator was also studied under a harsh vibration loading level, and the results confirmed its wide applicability without degradation of the isolation capability. | - |
