Perform Drop test of mobile by using MIL-STD-810G standards

Objective :Perform Drop test of mobile by using MIL-STD-810G standards

Drop Test using MIL-STD-810G

Units used ;tone/mm/sec

Height According to Standard : 1120 mm

Velocity= sqrt(2gh)= sqrt(2*9810*1120) =4687.68mm/sec

Material used :ABS

Material Properties

Youngs modulus[E]:2e3MPa

Yeild Strength [SIGY]=30MPa

Poisson’s Raio[NU]=0.29

Density[Rho]=1.1e-9 tonn/mm3.

Conclusions:

1. Drop test of mobile by using MIL-STD-810G standards was performed successfuly
2. Vonmises stress of 5.587MPa was observed in the model.
3. No plastic Strain was observed as stresses genarated in the model is too low.
