CAE Body Structure Engineer

Duties

Capture information from a variety of sources inside and outside GM, building and running analytical models, interpreting results for customers, attending development team meetings, interacting with compartment integration teams. Participate in the development of new engineering analysis capabilities. Participate in Product Development teams on new, major, and minor designs, providing analysis to assess performance of new designs.

Develop methods for problem root cause analysis and identification. Build Finite Element Analysis (FEA) models from CAD solid models. Perform structural analysis on complete Trimmed Vehicle Structure consisting of BIW, Chassis Structure, Interior Structure (IP), Fixed Glass, Bumpers, Modules (i.e. CRFM, Battery), and Closures.

Use Finite Element Analysis (FEA) and other analysis methods to assess designs. work interactively with the Product Development Teams (PDT's) to share analysis results, provide design recommendations, and assure that product requirements are met and validated. Create and execute Finite Element Analysis (FEA) plans for assigned projects. Lead CAE suppliers and internal resources to meet program milestones and deliverables.

• Create CAE geometry or construct and update FEA models from NX math data.
• Debug 1st run vehicle structure models from suppliers.
• Perform and coordinate resources for virtual assessment of designs and compare results to performance requirements.
• Recommend viable design solutions to resolve any performance issues with mass and cost efficiency.

Interface with body SMT, validation, structure integration, N&V, and safety integration engineers to assure balance of vehicle structure requirements and design solutions. Conduct topology optimization to identify architectural load paths to close the gap to requirements and implement enablers into the math released. Plan and implement test and development programs to enhance CAE capability.

• Recommend process automators and CAE enhancements for CAE modeling software and solvers.
• Assist in developing new CAE techniques.
• Use CAE to explain results of physical testing and engineer solutions to resolve issues with validation and release engineers.
• Responsible for Virtual Assessment presentations for program management and formal CAE report documentation as required.

• Participate in Body Structure Product Development Teams (PDTs) to provide technical guidance based on CAE assessments.
• Stay abreast of new technology, competitive products, and latest CAE tools and trends.
• Hybrid Work Policy - 3 days In-Office, 2 Days Remote - Must be able to report to local office.
