F P T Factor of Safety 1 60, 3665 2 1 01, 3628 91 N 4 2 Side Impact Analysis. Therefore the impact force by speed limit is 3628 91 N In the case of collision by side impact the value of impact. The Quad Bike will have maximum of 1 68G force under force is calculated in the same way as in the case of frontal. acceleration limit Therefore the impact force is given by impact For the side impact the velocity of the vehicle is. F 1 68 M a taken as 48 kmph or 13 33 m s according to ENCAP The. 1 68 220 9 81 European New Car Assessment Program standard and. hence the force is calculated as , 3625 776 N, The values of the force are practically comparable F P T.
According to a research the body has to pass 6 8G force for Where . extreme worst case collision Therefore for static frontal P M V. analysis the force is calculated as 220 13 33, F 6 8 m a 2932 6 kgm s. 6 8 220 9 81 The side impact force is given by , 14675 76 N F 2932 6 1 01. 2903 56 N, Therefore the worst impact force 3628 91 14675 76. Therefore the side impact force by speed limit is 2903 56. 18304 67 N N , Now this calculated force was placed on the front part of The Quad Bike will have maximum of 1 35G force under. the frame on ANSYS The result obtained along with the acceleration limits Therefore the impact force is given by . image is as follows , F 1 35 220 9 81, 2913 57 N.
The values of the force are practically comparable . According to a research the body has to pass 2G force for. extreme worse case collision for side impact Therefore for. static side impact analysis the force is calculated as . F 2 m a, 2 220 9 81, 4316 4 N, Therefore the worst impact force . F 2903 56 4316 4, 7219 96 N, Now this calculated force was placed at the side part of the. frame on ANSYS The result obtained along with the image.
