DESIGN OF POLE CLIMBER FIRST MODE ENGINEERING: DAVID BRUNEAU – MICAH BROWN – LIAM ARSENAULT – JUNWEI CHENPENG (A MEANS TO ADMINISTER VIBRATION BASED STRENGTH TESTING FOR IN SERVICE UTILITY POLES)

PROBLEM Newfoundland and Labrador Hydro desire a numerical means of testing the strength of rural in service utility poles Let poles stay in service for longer Prevent catastrophic pole failure Allow trending of pole strength and failure conditions Current tests are insufficient or inefficient Auditory hammer test Fly-by and video capture “Pole Tester” Source: CBC

1 - Climbs Pole 2 - Places Sensors 3 - Applies Impact PROJECT DELIVERABLE

CRITERIA & CONSTRAINTS Device must: Be lightweight Deliver multiple impacts Scale tapered utility pole Place multiple sensors and remove Be rugged enough to not break

DESIGN METHODOLOGY For each module FME Delivered: 1.Rough Design 2.Physical Proof of Concept 3.Refined Design Refined design should be buildable by skilled technicians 1 23

BUDGET Proof of Concept Budget: $500 Refined Design budget of ~$10,000 Refined Design construction: out of Term 8 Project scope

COMPLETED DESIGN - ASSEMBLY OF MODULES Impact Module Sensor Placement Module Both are mounted on the Climbing Module

CLIMBING MODULE – FINAL DESIGN 1 2
