Opposite impact energy dissipation device

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...

AI Technical Summary

Problems solved by technology

[0003] For the usual vibration isolator, due to its low natural frequency, it will produce a large relative displacement response under a certain impact, which may exceed the deformation capacity of the external piping system of the equipment, and even exceed the limit of the vibration isolator itself Shapeshifting ability

At present, in order to improve the shock resistance of the vibration isolator, a limiter is usually installed in the vibration isolation system. Although this method can reduce the relative displacement amplitude, it will cause the secondary impact problem of the system
