1 Reliability predictions in product development Proof Engineering Co

2 Contents Review of reliability theory Ways to predict part reliability Converting parts reliability into a system reliability Ways to improve reliability 2

3 Uses of reliability predictions Internal Compare competing designs Find design weaknesses Objectives for testing Estimate warranty costs Used for marketing purposes External Customer requirement Maintenance budgeting 3

4 Reliability definitions Reliability is the probability that a product or service will operate properly for a specified period of time under the design operating conditions without failure. Mean Time To Failure (MTTF): It is the average time that elapses until a failure occurs. Mean Time Between Failure (MTBF): It is the average time between successive failures. Failure rate is the rate of product failures expressed as a function of time. λ = 1/MTBF 4

5 Physics of Failure models Basic theory Reliability models are based on a number of statistical distributions Exponential distribution with constant failure rate is very common and simplest to use for hardware MIL-HDBK -217, NPRD etc. 5 MTBF

6 Parts reliability modeling Goal determine failure rate (MTBF -1 ) of a part Method I Parts Count (MIL-HDBK-217 for electrical components, NPRD 2011 for mechanical components). Based on historical part failure rates, assigns default failure rates depending on part category. Method II Parts Stress (MIL-HDBK-217 for electrical components, NSWC for mechanical components -Adjusts default failure rates with factors that account for stress, temperature complexity, etc. ss = G * Q * S * T ss = Steady State Failure rate; G = Generic or Base Failure Rate Q = Quality Factor; S = Stress Factor; T = Temperature Factor Method III Physics of failure modeling. Based on detailed simulation of physical failure modes and lifecycle usage conditions. 6

7 Parts count reliability prediction Electrical components use Mil-HDBK 217 Mechanical components use NPRD 2011 Classify part in suitable category (i.e. bracket) Read failure rate Convert to needed environment if data in needed environment is not available Recommend to use ALD MTBF calculator (freeware) for Mil-HDBK 217 Recommend to use electronic copy of NPRD 2011 from Reliability Information Analysis Center, RIAC (\$175) 7

8 Parts stress reliability prediction Electrical components use Mil-HDBK 217 Mechanical components use NSWC 2011 Classify part in suitable category (i.e. bracket) Perform calculations or software to obtain failure rate Recommend to use ALD MTBF calculator (freeware) for Mil-HDBK 217 Recommend to use NSWC 2011 Handbook of Reliability Prediction Procedures for Mechanical Equipment from Naval Surface Warfare Center (public domain with registration) 8

9 Physics of failure (POF) predictions Define realistic product requirements. Define the design usage environment. This usage profile defines the mechanical, thermal, electrical and chemical loads over time. Identify potential failure sites and failure mechanisms. Characterize the materials and the manufacturing and assembly processes, including defects. Design to the usage and process capability. The design stress spectra must be based on the anticipated lifecycle usage conditions. Electrical loads (Power dissipation, Voltage, Current) Environmental loads (Temperature, vibration, shock, pressure, humidity) Materials and geometry Life cycle (Mission) profiles including operation, storage and transportation Stress analysis (FEA/CFD) Reliability (compute MTBF) 9

10 Comparison of methods Part count (NPRD 2011) =2.1 failures/million hours Part stress (NSWC) =0.505 failures/million hours Example -1/4 screw Preloaded to 30 ksi, 5 ksi oscillating stress, 100 cycles per hour, 40 deg C operating temperature, A286 alloy. Physics of failure Reliability Model = fatigue (crack growth ) Predicted life =2.5e8 cycles =2.5e6 hrs =0.4 failures/million hours 10

11 Environmental factors Environment classification per MIL-HDBK-217 Reliability is drastically affected by the operational environment Part count reliability data for different operational environments may be converted Part stress or physics of failure based predictions account for the operating conditions implicitly 11

12 Accepted failure rate data sources Mechanical parts count Electronic parts count 12 Mechanical parts stress

13 System reliability - series systems The failure rate of the system is simply the sum of the failure rates of the individual devices 13

14 System reliability parallel systems Parallel components are accounted in redundant systems 14

15 Prediction procedure Obtain part list Sum failure rates of all parts=assembly failure rate Invert to obtain MTBF Classify parts per relevant standard Is goal reached no yes Done Lookup typical failure rates Per category Perform parts stress analysis on parts with larger failure rates Multiply failure rates by quantity of each part Is goal reached yes Perform physics based analysis Is goal reached yes 15 redesign no

16 Confidence of reliability predictions All predictions are only estimates Part count methods are very conservative (for properly designed equipment) Part stress methods may dictate failure models that do not govern Physics based modeling is probably best but does not include human factors, unexpected operating conditions etc Can not predict faults not considered 16

17 Ways to improve reliability predictions Reduce part count by combining parts Use parts stress or physics of failure models Redundant systems (last resort) Consider if part s fault necessarily leads to failure in operation of the system 17

18 Reliability software Many on the market Most seem to focus on electronic components and lag the latest mechanical databases (often a rigid requirement) We use spreadsheets combined with ALD MTBF calculator and NPRD electronic database 18
