California PE Mechanical Engineer Needed for FEA Structural Certification of Agricultural Tractor ROPS (Roll-Over Protective Structure) Anyone

About the job

Project Description:
I have designed and manufactured a compact, low-profile electric agricultural tow tractor for strawberry fields. The vehicle features a custom-built Roll-Over Protective Structure (ROPS). Since the tractor operates with a peak power of 42 HP, it falls under California OSHA (Cal/OSHA) Title 8 CCR § 3651 regulations, which mandate a certified ROPS for employer operations.
I am looking for a Licensed Professional Mechanical Engineer (P.E.) registered in the State of California to perform a digital Finite Element Analysis (FEA) to structurally certify this ROPS without the need for destructive physical testing.

What I Provide:
---Complete and accurate 3D CAD digital files of the tractor chassis and the ROPS structure exported in universal .STEP format.
---Exact material specifications.
---Total Gross Vehicle Weight (GVW) metrics.

Scope of Work Required:
---Perform a structural FEA simulation based on standard industry roll-over protection criteria (such as SAE J2194, ASAE S383, or equivalent OSHA 1928.51 test loads) tailored to the vehicle’s specific mass.
---Verify that the structure withstands static/dynamic load requirements and ensures the operator's critical clearance zone (Deflection Limiting Volume) remains intact.
---Deliver a comprehensive engineering report detailing the calculations, boundary conditions, and stress/strain results.
---Mandatory: The final report must be officially signed and stamped with a valid California Professiona... read more

---Mandatory: The final report must be officially signed and stamped with a valid California Professional Engineer (P.E.) seal so it can be presented to Cal/OSHA during inspections and used to create our regulatory compliance label.

Requirements for Applicants:
---Must hold an active and verifiable Professional Engineer (P.E.) license in California.
---Proven experience in FEA structural analysis, stress testing, or vehicle safety structures.
---Please provide a brief quote and your estimated turnaround time for the analysis. read less
