Condition, Lubrication, and Failures Flashcards
1
Q
The process of monitoring a particular condition in machinery (proactive)
A
- temperature
- sound
- vibration
2
Q
Types of monitoring (5)
A
- visual
- temperature
- ultrasound
- debris detection sensors
- performance analysis
3
Q
definition of visual monitoring
A
one of the most basic, but it is not monitoring if no feedback or report
4
Q
examples of temperature monitoring
A
- temperature sensors
- thermography
- IR thermography
5
Q
Types of failure (7)
A
- overloading
- buckling
- impact
- creep
- fatigue
- wear
- thermal shock
6
Q
Overloading
A
- stress exceeding or thermal overload
- material selection
- product design
- environmental conditions
7
Q
Impact Failure
A
- strength or toughness of the material
- colliding objects
- sudden force
8
Q
Creep
A
- constant loads
- occurs even when the stress is below the failure stress
- material
- time-dependent
- permanent deformation
9
Q
Fatigue is due to what type of loading?
A
cyclic loading
10
Q
three stages of fatigue
A
- initiation
- propagation
- fracture
11
Q
Wear and Tear due to… (3)
A
- friction or erosion
- heat loss
- seizing
12
Q
Definition of thermal shock
A
occurs due to rapid cooling or heating of material during preparation
