Embodiment Construction

[0025] A counter-moving impact energy dissipation device, characterized in that: a transmission channel and an energy consumption channel connected in series are set between the equipment and the equipment carrier, and the cross-sectional area of ​​the input end of the transmission channel is larger than the cross-sectional area of ​​the input end of the energy consumption channel; The top of the channel is connected to the equipment, and the bottom of the energy-dissipating channel is connected to the equipment carrier; the transmission channel is provided with a first medium for transmitting impact energy, and the energy-dissipating channel is provided with a second medium for consuming impact energy. The compressibility of the medium is less than the compressibility of the second medium. Since the transmission channel is connected with the equipment carrier, when impacted, the equipment carrier transmits the impact energy to the energy dissipation channel through the transmi...

Abstract

The invention discloses an opposed impact energy consumption device. A transmitting channel and an energy consumption channel communicated with the transmitting channel in series are arranged between equipment and an equipment carrier, and the sectional area of the input end of the transmitting channel is larger than that of the input end of the energy consumption channel. The top end of the transmitting channel is connected with the equipment, and the bottom end of the energy consumption channel is connected with the equipment carrier. A first medium transmitting impact energy is arranged in the transmitting channel, a second medium used for consuming the impact energy is arranged in the energy consumption channel, and the compatibility of the first medium is smaller than the compatibility of the second medium. When a system is not impacted, original vibration isolation performance of the system will not be affected; when the system is impacted, partial impact energy is consumed in the mode that gases are quickly compacted and released so that the impact resistance performance of the isolated equipment can be improved.

Description

technical field [0001] The invention relates to a power device and an anti-shock isolation device of a precision electronic instrument, in particular to a counter-moving impact energy-consuming device of a power device in the case of a non-contact explosion. Background technique [0002] The impact resistance of ships and machinery equipment and the equipment they install or carry when they are subjected to external large energy impacts is an extremely important indicator of vitality in ship platform systems and machinery equipment systems. Therefore, countries all over the world pay great attention to their impact resistance issues. In the design of ships, mechanical equipment and equipment, equipment with good impact resistance is usually selected and anti-shock protection measures are adopted for the equipment to ensure the safety of equipment in ships and mechanical equipment. The use of vibration isolators is a better impact protection measure. [0003] For ordinary vi...
