Dassault Systèmes is enabling Royal Enfield a unit of Eicher Motors Limited to drive innovation and efficiency across the design and product development lifecycle for all existing motorcycle models and in their recently expanded product portfolio to manufacture genuine motorcycle accessories. Royal Enfield has performed the complete piston durability and high fidelity simulation of critical parts like powertrain and chassis using Dassault Systèmes SIMULIA applications on the 3DEXPERIENCE platform for realistic simulation, before any prototyping.
In the extremely competitive two-wheeler segment in India, product innovation, improved performance and reliability becomes key differentiators for companies. Product innovation, design, and manufacturing with real-time simulation are providing OEMs and their suppliers the confidence to efficiently manufacture and reduce the cost of prototyping and reduce time to market of new products. Powered by the 3DEXPERIENCE platform, Dassault Systèmes SIMULIA application delivers realistic simulation applications that enable users to explore real-world behavior of product under varying usage conditions.
Rod Giles, Lead CAE & CAD, Royal Enfield said “We have been using Dassault Systèmes SIMULIA applications for over five years now to perform realistic simulation, before any prototyping in our product innovation, development and manufacturing processes. We have successfully launched India’s first twin-engine motorcycle Interceptor and Continental 650 performing the complete piston durability using Dassault Systèmes SIMULIA. We have deployed solutions such as Abaqus, Isight, Tosca, fe-safe and Simpack to perform high fidelity simulation of critical parts like powertrain and chassis, at the design stage reducing significant costs and time in prototyping and in manufacturing.”
Pistons in internal combustion engines are subject to gas loads from combustion acting on the crown, inertial forces arising from the piston vertical motion in the bore and thrust forces acting on the edge arising from the action on the connecting rod. However, in order to correctly evaluate the durability of the piston, the effect of piston secondary motion must be taken into account. The piston secondary motion of the newly launched two-cylinder engine has been completed using Simpack. Finite element analysis of the piston was carried out at a number of discrete times using Abaqus and a fatigue analysis carried out using fe-safe, which includes temperature dependent material properties. In this way, the fatigue damage can be calculated for a given engine operating condition. The total damage is found by summing the damage in fe-safe for each engine operating condition for the complete engine durability test.
“Consumer expectations, regulatory bodies, international laws, environment concerns are constantly pushing OEMs and suppliers to innovate new products, designs, systems at much faster pace. This has reduced the time of a design concept, visualization, production manufacturing and supply chain significantly to less than two years. In such circumstances real-time simulation of the vehicle, parts and components are critical reducing the time to market and cost of testing on physical prototypes” said Samson Khaou, Managing Director - India, Dassault Systèmes. “Royal Enfield is regarded as a legend in motorcycling and we are happy that they have trusted our simulation applications on the 3DEXPERIENCE platform to enhance their product innovation journey.”
