The assisting mechanism of hammer in dredge haul is to accumulate energy with wire pull, draw inner pole firstly, release by pin framework, acceleratc core piece, strike hammer shell, produce great instantaneous wallop, drag dredge to break op stone immediately, restore with reposition spring, and work again finally
該機構在拖網取樣時利用鋼纜拉力蓄積能量拉動內部拉桿，並通過銷軸機構釋放能量加速沖擊芯塊，撞擊殼體產生巨大的瞬時沖擊力，拽動拖網破碎巖石，然後使用復位彈簧使機構復位，重新工作。The reduced pressure detector assembly shall consist of two independent torsion spring check modules, a differential pressure relief valve located between and below the two modules, two drip tight shutoff valves, and required torsion spring check modules and relief valve shall be contained within a sleeve accessible single housing constructed from 304 ( sch 40 ) stainless steel pipe with groove end connections
這種減壓檢測器總成應該包括兩個獨立扭力彈簧止回閥模塊，一個位於兩個模塊之間的下方的差壓安全閥，兩個防滴漏關閉閥，並且要求扭力彈簧止回模塊和安全閥應該放置在一個套筒內，要易於接近帶溝槽連接的304 （目錄40 ）不銹鋼管的單個外殼。Steel tubes, concrete and the interface between steel and concrete were modeled by shell, 3d entity and contact element, respectively ; the constitutive model of steel tubes and concrete was elastic - plastic, while the interface was described by column ' s friction law
有限元模型中鋼管、管內混凝土和鋼管與混凝土界面分別採用殼單元、三維實體單元和接觸單元；鋼管和混凝土採用彈塑性本構模型，接觸面採用庫侖摩擦定律的本構關系。? by comparing the experimental data with the modeling results, it was found that the he in the projectile produces reaction after considerably long time. and the expansion velocity of the shell is about one hundred meters per second, far below the velocity driven by detonation ( about 2000m / s ). ? the post - test recovered fragments prove that the reaction violence remains on low level
?通過試驗結果和數值模擬的殼體邊界和徑向膨脹速度的對比分析，發現帶炸藥彈體在以120m s左右的速度撞擊鋼靶后，經歷了相當長時間后才產生反應，且此時殼體的膨脹速度僅在百米每秒的水平，遠低於爆轟驅動下能達到2000m s左右的速度。分享友人
