Taking Mass Out of Engine Mounts
All OEMs are looking for components that are lighter. But at the same time, they’re looking for components that are sufficiently robust. Speaking to that, Ludovic Chauvet, engineering expert with TrelleborgVibracoustic (tbvc.com), a supplier with particular focus on producing vibration control components for a variety of applications, including powertrain, said, “When designing high performance engine mounts it is essential to provide our customers with products which offer greater endurance coupled with less weight, therefore we are constantly looking for lighter materials, replacing metals with plastics.”
Case in point: cutting the weight of an engine mount by 30%.
This was accomplished, in part, through the use of a polyamide material from Solvay Engineering Plastics (solvay.com). In order to make sure that the mount that they were developing would meet the requirements, they used a service from Solvay, MMI Technyl Design. Solvay Advanced Polymers
The multifaceted MMI Technyl Design—MMI stands for multi-scale modeling, mechanical calculation, injection molding simulation—system allows designers to evaluate crash and fatigue resistance of injection-molded parts early in the design process. The software includes a comprehensive materials database and allows for a wide range of calculations.
Chauvet: “Our choice of utilizing MMI Technyl Design was determined by the quality of the material anisotropic data available for Technyl products. Building on the results, we developed a unique solution for designing and predicting the performance and manufacturing of structural components, while taking into account the production process.” He added, “Together with our FIAPLAST program for mechanical dimensioning, this unique approach enabled us to decrease the mass of our customers’ engine mounts by 30% and reduce time to market.”
