Without structural analysis no product can reach the production line. This is the must to have type of analysis for the safety of the product. We have expertise in structural strength and stiffness calculations. Stiffness of the structure directly impact the response of the system. For example stiff suspension of a car gives good road grip and handling, on the other hand soft suspension gives better comfort inside the car. For our automotive customer, we have provided solutions on structural integrity, identification of failure prone areas, stress concentration zone identifications, early prediction of crack and fatigue, material yield and buckling. We have an inbuild material library, which can be used for various industrial use.
FEA Workflow:We provided solutions to a handful of market leaders in the automotive world. Which involves early prediction of structural failure, vibrations and its effect on the overall system, fatigue and crack failure, harmonic response of the system etc.
Benefits:Topology optimization is important to understand the exact required shape of the product. Many a times product is too complex to define its final shape with the conventional approach. Hence, we take the help of computer simulations to optimize mass the performance of the product. The optimum shape of the product is finalized by applying the service loads on the product. Topology optimization algorithm is self-intuitive and understands the best possible outcome based on design constraints. Here the major intension is to make product light weight, save unwanted weight and material cost. But still obtaining the optimum required strength of the structure.

Durability and fatigue life prediction are part of product lifecycle management. We have expertise in fatigue calculations.

We have also provided solutions on selection of proper spring and dampers for the vehicle, and provided support to develop a robust process for the durability life prediction.

Benefits:Dynamic motion study or multi-body dynamics (MBD) belongs to the school of rigid body dynamics. Here we study the behaviour of different components related to each other. Motion study helps to understand the kinematics of the complete system. To build a robust product, this analysis is essential. Motion study also helps to understand the area required to move the parts of machine in the surrounding area. For our auto and robotics customer, we have provided the report on motion study, bearing forces extraction, acceleration profile of the various parts, trajectories traced by various parts of the product etc.
FEA Workflow:We provided solutions to a handful of market leaders in the automotive and robotics industries. Which involves early prediction of structural inertia, vibrations and its effect on overall system, motion intensity, geometrical behaviour, path trajectories of different components, force and efforts calculations, joint reactions, bearing forces and bearing selection based on radial/axial loads etc.
Benefits:Crash analysis is a very fundamental study considered in the automotive sector. As per government regulations vehicle structure should withstand typical crash scenario while safeguarding the occupants in the system. This study consists of loading the vehicle components up to 28 g of accelerations and validating the structural integrity. This needs a deep understanding of physics involved behind the computations. Our experts approximate the CAD model of the vehicle in a mathematical model, so that it would be solved in the virtual environment. Approximations are modelled in such a way that they will reduce the complexity of the system as well as should behave as close as possible to real life scenarios. We provided the solution to one of the leading automotive OEM to test their two-wheeler under the crash scenario. Here bike has undergone 28 g of acceleration which is the approximation of the bike front wheel hitting the wall at the speed of 25 kmph. We reported the modes of failure, plastic deformation, fracture zones back to customer.

Benefits:CModal and frequency response analysis is essential for fundamental understanding of the structural behaviour. Modes of vibrations are critical where the product is subjected to internal or external vibrations. Internal vibrations are coming from internal parts like the engine, unbalanced masses etc. External vibrations are coming from ground, earthquakes, wind loads, road loads etc. To ensure our product to withstand internal and external loads, we need to ensure how our product behaves with the surrounding world. Resonance is the phenomenon which needs to be avoided for the better durability of the product. Fundamental modes of vibration of the exhaust system should not match the engine’s dominant frequencies. Fundamental frequencies of the mobile tower should have lower frequencies than wind forces, otherwise wind will start swaying the tower. These frequency studies are carries out in FEA environment using computer simulations. We have provided solutions to heavy industry manufacturer for haul truck canopy analysis. Canopy was studied for modal analysis and its behaviour under road load frequency ranges & how the overall canopy structure will behave under the excitations from the rough mining roads. We have also predicted the radiated noise from the walls of canopy under the same conditions. For exhaust system modal analysis, we studied the overall vibration pattern of the exhaust system and checked whether it overlaps with the engine vibrations or not. If engine vibrational patter matches with exhaust system, then large amplitude vibrations could be observed. Which leads to catastrophic failure or unwanted vibrations.

Benefits:FRF (Frequency Response Function) is the transfer function of the structure which tells how the structure will behave with various types of input excitations given to the product. In short, it tells what is the noise coming out of the exhaust system when engine is running at certain speed. Or What is the amount of jerk the passenger will feel when car passes over a speed breaker at certain speed. This study helps us to understand our product better. It tells us how the product will interact with the surrounding elements. Hence this type of analysis gives overall understanding of interaction patter between the product and surrounding. It helps to understand effect of product on surrounding and vice versa.
