Vibration Analysis & Thermographyat Michelin’s Granton, NSTire Manufacturing Facility

2

Background to Michelin in Canada

• Michelin first established itself in Canada back in 1969• It produced its first tire in 1971 and currently has three tire

manufacturing facilities in Canada• Granton, NS facility produces:

– Passenger car tires– Light truck tires– Semi-finished rubber (to be delivered to other facilities in North America)

Safety & Introduction

• Site orientation started with a series of computer safety modules:– LOTOTO (Lockout/Tagout/Tryout)– Forklift/PIV & Pedestrian Safety– WHMIS– Site Chemical Hazards (particularly Asbestos)– Others

• Plant tour and insight into operations of different departments

3

Mentor & Background

• Worked under Mike Lord who is contracted by Michelin as a Reliability Technician

• Performs Condition Based Monitoring of various rotating equipment and certified in:– Vibration Analysis– IR Thermography

• Took part in data collection and analysis with different theory and techniques learnt on the job

4

Types of Equipment

• AC Motors• DC Motors• Pumps• Gearboxes• Fans

5

Types of Equipment

6

Vibration Analysis

• Used the CSI 2130 to collect vibrational data• Analyzed data using the AMS Suite: Machinery

Health Manager software

7

Vibration Analysis

• Acquired data from various equipment by following data routes– Transferred data routes onto CSI 2130– Followed routes and took readings as instructed by

mentor– Dumped data onto the computer for analysis

8

Vibration Analysis

• Viewed vibration data using AMS Machinery Manager– Noted key vibration frequencies and max amplitude– Determined frequency relations such as turning speed,

noting sidebands, line frequency etc.– Fault severity: Minor/Concern/Action

• Prepared report in accordance to Michelin format– Identified route– Grouped report by placing equipment into 3 fault

severities– Provided brief description and recommendation

Vibration Analysis

• What did I learn?– Identification of faults depending on equipment type

(AC motors, fans etc.) and reading type (axial, radial etc.)– Theory connected to faults (SCR frequency, GMF,

BPFO, BSF, looseness & types etc.)– How to take proper readings

• Safety first• Placing sensor in correct/optimal places and orientations (welds,

non hollow surfaces, hor. & vert. 90 deg. apart etc.)• Identifying poor readings from analyzer (sensor rocking, massive

discrepancies from last reading, fluctuating readings etc.)• Variable speeds

“DO THE BEST WITH WHAT YOU’VE GOT!”

12

Vibration Analysis

– Performed entire data routes• Transferring data into analyzers• Learned analyzer and its functions• Taking readings• Dumping data into computer

– Preparing reports• Identifying faults and severity• Recommending solutions

– AMS Machinery Manager• Various tools and functions (sidebands, harmonic families, peaks

etc.)• Creating and copying databases• Viewing trends and equipment history

13

IR Thermography

• Performed data routes of IR image collection– Used the FLIR ThermaCAM EX320 handheld IR camera– Learned different camera settings (emissivity, reflective temperature

etc.)– Focussed and thermally tuned images for data accuracy

• Analyzed max temperatures from images to see if within acceptable range

• Prepared sample IR report– Identified object parameters– Image and equipment details– Faults, recommendations and additional information
