Case (2) assumedmaximum bending to be under the forth roadwheel and it occurredat 30.5 seconds.In reality, there are many cases for thebending of the chassis which falls between these two load cases,and their effects must be considered. However, the complexityof the process leads to this simplification. This will bediscussed later when addressing the bending stresses in thedynamic finite element analysis.4.3.4Firing Load EffectsFore AFT Gun Breach DisplacementFig 112Fore AFT Gun Pitch Angle DisplacementFig 113Fore AFT Gun VelocityFig 114Fore AFT Gun AccelerationFig 115Chassis Longitudinal AccelerationFig 116Chassis Vertical AccelerationFig 116Maximum Vertical Forces in Road Wheels:L I to L7Fig 117Li, L4 and L7Fig 118L2, L3, L5 and L6Fig 119Results of the previous DAD analyses are attached for comparisonFig (120 - 122).107Inn-10'aW~vaU M"E4Hraft~ft10rlN;I_v,~_____aIn-r(99))-'5 zV81/.-22*-vi ~-~zLL~LALAO rys11 I99-i-cJ9biW109MOT 0F,707=FOR A7oTDEoF___lx'TE9)__cci1(5,Y(sy9;SVRWE'DP--TORSlDU &AP_ AN)D CMS UIVEm.,C) ls3c'FIGI'y88CATTB GEOMETRYROADWHEELS POSITIONS-RELATIVE TO C.G110--I,LP~Q-nTINt-U)I00~LINO 9IrN.1,j101!LJI..IE-'1j~~x07-Nicco0ojX-E-AE2U/yrL.JI/L'ADO3tu112C,2i-J-Ef\0~I..-)0tE-I.-I11C.,WO)In~I0U t-N.>In'LuL___2Euwcc__coo(sdD4 avojCOG(D114V-0zwOo0&.(NA0)w0zCC...
