Summary:

The small commercial vehicle business is driven by demand inlogistic, last mile transportation and white goods market. And tocater these businesses operational and safety needs, they requireclosed container on vehicle. As of now, very few OEM's provideregulatory certified container vehicle because of constrains tomeet inertia class of the vehicle. The paper focuses on design of adurable and extremely reliable container, made of the low-costeconomy class glass fiber and core material. The present workprovides the means to design the composite container for the N1category of the vehicle. The weight of after-market metal containerranges between 300-350 Kgs for this category of vehicle, whichaffects the overall Fuel Economy and Emission of the vehicle. Adetailed CAE analysis is done to design composite containersuitable to meet inertia class targets and to achieve weightreduction of 30-40% as compared to metal container. The design isvalidated and optimised using Inertia Relief Analysing, considering38 load cases derived from real-life road running condition likepothole braking, bump steer et cetera Additionally, 40 kg of horizontalload on the side walls (person leaning on side wall) and 750 Pa oflive load on roof panel (person climbing on roof) is alsoconsidered. The container is designed considering overload of 50%over the GVW of the vehicle. The pre-processing of the model isdone using Altair HyperMeshTM, the solver used is AltairOptiStructTM and post-processing is done using Altair HyperWorks2019. Maximum Stress Criteria is used as the failure criteriaconsidering maximum allowable stress as 99 MPa and Factor of Safety(FOS) as 1.3. Variable laminate structure design is used acrossdifferent components of the container to optimize the overallweight. The designed container included additional features likewide door opening, integrated magnetic stopper, tail lamp, cabinlight, container window
