Concepts of a Battery Box Vibration Absorber for a Durable, Lightweight Structure

Company: Volvo Group North America

Intellectual Property: YES

To develop ICE or Electric vehicles, it is necessary to verify the durability of the chassis (i.e. Fig. 1). This proposal explores the idea of vibration absorbers which are installed in/on a battery box. This device improves vibration fatigue and achieves robust durability of the chassis frame. This proposal will, consequently, be used to discuss design concepts for lightweight structure to develop ICE/BE vehicles. This project will be carried out in the 5 steps: Step 1. Review vibration of 2 DOF system and study on Vibro-fatigue Step 2. Study on TRIZ for idea creation for vibro-fatigue Step 3. Train for CAE S/W: ANSA/Metapost and Nastran Step 4. Develop ideas for reducing vibration of battery box through DFSS(Design for Six Sigma) Step 5. Validate the idea for vibro-fatigue and discuss on concepts for lightweight structure



Our mission is to help bring the real-world into the classroom by providing engineering students with practical hands-on experience through industry-sponsored and client-based capstone design projects. Since its inception, the Learning Factory has completed more than 1,800 projects for more than 500 different sponsors, and nearly 9,000 engineering students at Penn State University Park participated in such a project.
