AI Technical Summary

Technical Problem

Existing vibration reduction methods for vehicle-mounted liquid hydrogen cylinders suffer from problems such as narrow vibration reduction frequency band, unreasonable installation methods, easy loosening of vibration reduction structure, and difficulty in suppressing vibration in all aspects, resulting in safety hazards and insufficient structural stability.

Method used

An externally mounted tuned mass damping vibration reduction device is adopted, including a base, outer ring, inner ring, guide slide, vibrator, top rod, spiral compression spring and internal hexagon bolt. By tuning the frequency to match and consume vibration energy, it achieves all-round vibration suppression.

Benefits of technology

It effectively dissipates the vibration energy of liquid hydrogen cylinders, improves operational safety and structural stability, and avoids safety hazards caused by long-term vibration.

Abstract

本发明涉及车载储氢设备技术领域,尤其涉及一种车载液氢气瓶外置式调谐质量阻尼减振装置,包括基座和设置在基座上方的液氢气瓶,所述基座设置有两个,且两个基座对称设置在液氢气瓶的下方,两个所述基座和液氢气瓶之间设置有用于消耗液氢气瓶振动能量及抑制振动的阻尼减振机构。本发明中,通过在原先的基座和液氢气瓶之间设置了外环、内环以及多个环形阵列分布的导向滑筒、振子、顶杆、螺旋挤压弹簧和内六角螺栓,可有效消耗液氢气瓶车载运输过程中的振动能量,并可抑制液氢气瓶的振动作用,从而提升了车载液氢气瓶的运行安全性以及结构的稳定性。
