Present work describes the dynamic analysis of roll cage using computer simulation collision from different sides viz. front impact termed as case 1, front side impact termed as case 2, rear impacts termed as case 3, rear side impact termed as case 4, and bottom impact termed as case 5. The collision occurs at speed of 40 km/hr. To simulate the result of transient dynamic analysis nodal solutions are obtained to access maximum relative deflection on various selected nodes of the chassis. The severity of impact is ascertained based on the maximum deflection at nodes stresses induced and velocity peak. The maximum deflection is obtained for the rear impact of 22.3 mm. The methodology proves itself in understanding the impact of the collision on vehicles and ensuring the safety of the vehicles. |
