: Houses the hydraulic fluid and nitrogen gas charge, featuring a honed inner surface for smooth piston travel.
You must perform a shock qualification by calculation, explicitly considering these factors for each principal axis: br 3021 shock manual
Shock management is not just about keeping equipment working; it is about ensuring the crew's safety and the ship's operational effectiveness. When an underwater explosion occurs, it creates a massive shock wave. This wave travels through the water and hits the ship’s hull, transmitting intense vibrations and sudden, high-velocity movement to the machinery installed inside. Risks of Inadequate Shock Protection : Houses the hydraulic fluid and nitrogen gas
: Focuses specifically on shock mountings , providing details for rubber mounts like the "Type PD" series used to isolate equipment from hull movement. Technical Shock Grades This wave travels through the water and hits
Use your breaker bar and appropriate socket to loosen the lower mounting bolt. Remove the nut, but leave the bolt in place. Move to the upper mount and remove the upper fastening hardware. Returning to the lower mount, carefully tap the bolt out using a brass drift pin or rubber mallet. Slide the old shock assembly out of its mounting pockets. Step 3: Inspecting and Preparing the Mounting Pockets
Unlike regular vibrations, high-impact shock is characterized by sudden, violent movement. The manual sets guidelines for managing this, particularly in ensuring that items like control panels, generators, and weapon systems remain secured and functional, similar to requirements outlined in modern specifications like D-03-003-007/SG-000. 2.
