Addressing Design Development Challenges through Simulation Driven Platform

Auto Original Equipment Manufacturers (OEMs) are looking to their suppliers to be their development partners by moving up the value chain. Suppliers are expected to partake in joint Research & Development (R&D) activities by being involved right from the conceptual stage, thereby adopting a more collaborative approach to the entire product development process where they contribute at each stage of the development cycle.

The key factors for automotive supplier competitiveness are

• Reduced product development time.
• First time right products.
• High-value offerings with superior technology at affordable costs.

To achieve these above-mentioned goals, OEMs are insisting component suppliers invest in simulation technologies.

Focus on Simulation by Automotive Suppliers

Overcoming engineering challenges faced by automotive suppliers.

Automotive suppliers are facing many challenges in having in-house simulation capabilities compared to that of OEM’s, the primary challenges being upper caps on budgets & constraints of hiring expert manpower and retaining them. Access to relevant data to validate the designs and establishing robust virtual/test methodologies to match OEM expectations is another concerning factor for the suppliers.

Simulation Tools that the Supplier Segment Needs

The majority of expectations are to find out cost-effective, reliable methods and solutions which can lead to better, lighter, faster and low cost engineered products.

One of the ways to overcome these challenges is to invest in simulation technologies that require an affordable initial investment, the ownership cost of which is low, the codes are reliable & proven, and the suite of tools provide suppliers access to a broad range of solvers (a true multi-physics environment) helping them pick and choose the solvers as per their simulation requirements. Another important factor in consideration is that these tools need to be easy to use and the existing manpower should be able to learn quickly and develop proficiency so that they can harness the full potential and derive maximum benefits that these tools have to offer.

The need for solver technologies addressing various physics is very dynamic. Their usage cannot be accurately predicted in advance and therefore investing in multiple solvers is not a commercially viable solution for the organization. Altair HyperWorks® through its patented Units based licensing system gives customers access to multiple solvers under one umbrella. Users get access to different solvers addressing multiple physics, which helps them to apply the correct one based on the challenge at hand, thus making it a smart choice for the organization to achieve robust product design through reliable & accurate simulation tests, at an affordable investment. Meanwhile, the major engineering decisions can be made easy with predictions through simulation.

Simulation Implementation at Endurance Technologies

In the early stage of in-house simulation implementation at Endurance Technologies, HyperWorks was being adopted primarily for pre and post processing due to its extraordinary FE modeling solutions. During the stage of establishing high fidelity finite element modeling for our applications, HyperMesh® has been used extensively to build analysis models for Structural, Thermal, Computational Fluid Dynamics (CFD), and Multi-body solutions and OptiStruct® for durability analysis with HyperView® as standard post-processing. With constant support, Altair team helped us in exploring and implementing various HyperWorks solvers at Endurance Technologies.

Altair Solution Offerings

Altair HyperWorks offers a wide range of simulation applications – which includes Linear Static, Non-Linear Implicit / Explicit, Multi-body Dynamics (MBD), CFD, Electromagnetic, Optimization etc. - in the form of HyperWorks Units (HWU), to address specific industry requirements. For example, most of HyperWorks applications are available for 50 HW Units. A user can access any application, which takes up the requisite set of HWUs and returns them to the common pool on network server once he is finished with his work. This flexibility allowed us to start exploring HyperWorks solvers for different applications, involving Linear & Non-Linear analysis (OptiStruct), Crash & Impact simulations (RADIOSS®), Kinematic & Dynamics simulations (MotionSolve®), Flow Dynamics (RADIOSS FSI/AcuSolve®).

HyperWorks Solver Adoption

At the stage of solver evaluation, exploration and test validation process, there was a need for maximum hand-holding and knowledge transfer. A strong collaborative activity with Altair & DesignTech (business partner of Altair) technical team stretching over an extended period of four years for a variety of simulation solutions helped us in benchmarking the appropriate simulation methodologies. Through these collaborative initiatives, we were able to establish a simulation approach suitable to our design and development process that ensured we developed better products faster and with greater accuracy than before.

“Altair India and DesignTech technical teams are extremely co-operative, responsive and competent for resolving day-to-day technical issues that occur in our regular simulation activities. This increased our confidence in capabilities of Altair simulation solutions, inspiring us to explore more offerings from Altair HyperWorks going forward.”Girish Kokane, Asst. General Manager (R&D)-Advanced Engineering Endurance Technologies Ltd.

Here are few of the real-time cases listed for which simulation approach has been well established at Endurance Technologies.

• Telescopic suspension virtual validation using RADIOSS & MotionSolve.
• Strength and Vibration analysis using OptiStruct.
• Design correlation with tests using HyperStudy® and HyperGraph®.
• Clutch performance studies using MotionSolve.

Altair HyperWorks helped in the smooth implementation of the variety of CAE simulations during product design & development stage at Endurance Technologies, India.

Endurance Achievement

Adoption of Altair simulation solutions effectively facilitated the achievement of reliable results, with test

correlations, study product behaviour under several conditions and constraints, and also the exploration of various ‘what- if’ scenarios. These tools helped us articulate and measure the costs and effects of possible design errors while helping us arrive at simple yet accurate solutions for our complex engineering problems. Today HyperWorks technologies are playing a vital role in product development cycle and simulation has become an integral part of NPD process at Endurance Technologies. Endurance has developed its own Virtual Verification Process which is automated with the help of Altair Enterprise Solutions Group in order to cut short simulation lead times & improve the results consistency.

Future Road-map on Simulation and HyperWorks at Endurance Technologies

Integration and automation of advanced processes in HyperWorks will be a new area to explore as it would help companies capture & establish best practices or ideal approaches to address complex, frequently solved problems and thus reduce to a great extent the duplication of work or repetitive efforts. We plan to explore other offerings under HyperWorks solutions, viz. Click2Cast®, solid Thinking Inspire®/Evolve®, which can strengthen our engineering judgments and shorten our design and development cycle on our product line. Going forward, Endurance Technologies plans to venture into full vehicle level design activities and anticipates an increased application of HyperWorks technologies in the area of optimization and design of experiments. We believe that Altair’s further research into HyperWorks solutions and continued investment in addressing newer physics will address emerging domains thereby enabling Endurance address newer challenges upfront with simulation.
