At Research and Development you will be a key contributor to the next generation outstanding luxury cars from Volvo. Together with other engineers around the world, you and your team will create innovative human-centric car technology that makes life less complicated and more enjoyable for people. Are you interested in design and connected car technology? Do you share our passion for people, the environment and our urge to create a superior driving experience? Research and Development is the place for you to prosper.

This thesis work will be carried out within the Powertrain Mount department, which is a part of Volvo Cars´s Research and Development organization.

Background

Powertrain suspension components utilize natural rubber, with filled carbon particles, to isolate the engine vibrations from the car body. As part of the design requirement, these components should meet requirements from different attribute area such as NVH, driveability, durability and ride comfort.

Usually the requirements from attribute areas are specified in static stiffness, dynamic stiffness and damping over engine operational loads and frequencies. Requirements are also stated in terms of durability specifying the total load cycles required before failure. Selecting the rubber type that is best suited for the specific application is challenging and requires extensive development work. The basis for currently performed simulations are material parameters that are extracted using rubber specifications of various types used by external resources.

Scope

The different powertrain suspension components are, to a great extent, utilizing hyperelastic materials such as natural rubber. The load sequences are greatly varying in terms of amplitude and frequency. The component is to withstand a large number of cycles that represents the total life cycle for a component installed in a car.

There is a need of S-N curves for a series of commonly used rubber materials in order to evaluate the number of cycles to failure. In order to obtain adequate data regarding fatigue and fracture, testing and analysis is to be performed at Volvo cars test facilities.

Steps;
  • Gain general knowledge of powertrain suspension system.
  • Literature study with focus on rubber material and fatigue.
  • Define test sequence and set up test procedure.
  • Evaluate fatigue software from Simulia, fe-safe/Rubber.
  • Perform fatigue and fracture testing.
  • Analyse data from test results.
  • Perform fatigue simulations for correlation with test data.
  • Document results.
