• No.of pin -II element (pin fixing) of Therefor, the following value is obtained JMTRC (liEUJ

[NJ The force acting on Lhe fuel plate d11e to the acceleration is given as follows, F - mN Where, F: Force acts on fuel plal.c when dropping (NJ m: Mass of fuel plate, = * [ kg)

N : Design acceleration =tlli [m/s 2

]

Therefore the following value is obtained.

f * {NJ from the above, the retaining force of the pin is larger than the dropping force of the fuel plate by the acceleration, th* fuel plate docs not slide from fixing.

When the fuel plate, fixed with pin at the both ends, is freely dropped, the tensile force occurs at the pin portion of the fuel plate and is given as follows ,

Where,

w. ~ mx N n/2

[NJ er, : Stress of fuel plate pin [N/mm 2 )

N  : Design acceleration, N =Ila [m/sec'J A  : Effective sectional area of pin {mm 2 ]
