Video shows multiple load steps of a multi o-ring piston-cylinder assembly. This analysis includes fluid pressure penetration applied to all O-rings. Here is the description of various load steps involved:
-Load step 1: O-rings establish contact with the gland surfaces.
-Load step 2: Cylinder is assembled over the piston. This squeezes the O-rings in the groove.
-Load step 3: Piston is displaced slightly back to ensure the correct position of the O-rings within the gland before pressure load is applied.
-Load step 4: Pressure and or temperature loads are applied while the piston is static.
-Load step 5-9: Piston is displaced back and forth simulating the actual working of the device under pressure and or temperature loads.
