The results, findings, and analytical investigation of an experimental study conducted on the hydrostatic implosion of filament wound carbon fiber epoxy composite tubes within partial confinement are presented. Implosion in geometries varying in length and diameter is initiated within a tubular confining structure with one end closed and one end open to a free-field, hydrostatic environment. Structural deformation behavior is captured and quantified using high speed cameras in conjunction with 3D digital image correlation (DIC). Water hammer pulses resulting from implosion are measured at various locations in the confining chamber and are shown to behave as a damped harmonic oscillator. Water hammer behavior is thus experimentally characterized for each geometry by determining average values of amplitude $\Delta P_{max}$, frequency of oscillation $f$, and damping ratio $\xi$. It is shown that $f$ decreases with increasing implodable volume to confinement volume ratio $V_i/V_c$, and is theoretically determined with excellent correlation to experimental results. Finally, amplitude of oscillation $\Delta P_{max}$ is theoretically determined and used in conjunction with theoretically determined $f$ and experimentally determined $\xi$ to fully define the hammer wave oscillations resulting from partially-confined implosion.

介绍了在部分封闭条件下对长丝缠绕碳纤维环氧复合管进行静水内爆的实验研究的结果，发现和分析研究。长度和直径变化的几何形状的内爆是在管状封闭结构内开始的，封闭结构的一端封闭，一端开放至自由场静水环境。使用高速相机结合3D数字图像相关性（DIC）可以捕获并量化结构变形行为。由内爆引起的水锤脉冲在密闭室内的各个位置进行了测量，并显示为阻尼谐波振荡器。因此，通过确定振幅的平均值，可以对每种几何形状的水锤行为进行实验表征$\Delta P_{米\mathrm{一种}X}$，振荡频率 $F$和阻尼比 $\xi$。结果表明$F$ 随不可溶体积与封闭体积之比的增加而减小 $V_{\mathrm{一世}}/V_C$，并且在理论上与实验结果具有极好的相关性。最后，振荡幅度$\Delta P_{米\mathrm{一种}X}$ 在理论上确定并与理论上一起使用 $F$ 并通过实验确定 $\xi$ 完全定义部分受限内爆导致的锤波振荡。
