A typical vibration measurement system includes a device to sense the vibration accelerometer and an instrument to measure the level of vibration This equipment also has settings for measuring frequency a frequencyweighting network and a display such as a meter printer or recorder
4 MILSTD1671A environmental vibration testing and MILS901D equipment shock testing provide complementary requirements for the survivability of shipboard equipment 5 This specification was revised to address the following a Requirements for test instrumentation and testing machines b
The need to operate a pump at or near its best efficiency point BEP is emphasized and why it is important Descriptions of the opposite flow problems of lowflow and cavitation are given The need to gather periodic data on pressure and flow along with vibration is stressed Suggested machine locations for pump vibration monitoring are given
The final vibration test load specification for an automotive product can be presented in either sinusoidal sweep or random vibration profile formats as per the customer preferred and both will have an equivalent durability damage level for the given test duration and reliability parameters
ISO 194012003 Mechanical vibration Balance quality requirements for rotors in a constant rigid state Part 1 Specification and verification of balance tolerances gives specifications for rotors in a constant rigid state according to their machinery type and maximum service speed These recommendations are based on worldwide experience
rotor will require multiplane balancing If a rotor is balanced on a low speed balancing machine assuming it is rigid and then in service becomes flexible then unbalance and thus high vibration will be the result Typical machines which fit this category include steam and gas turbines multistage centrifugal pumps compressors and paper
force will cause a vibration and that vibration can be described in terms of acceleration velocity or displacement The force that will cause the vibration must overcome the structures mass stiffness and damping properties These properties are inherent to the structure and will depend on the materials and design of the machine
Machine monitoring made simple The SKF Machine Condition Advisor is a rugged easytouse hand held device that simultaneously measures vibration signals and temperature to indicate machine health and bearing damage providing early warning of machine problems before a costly breakdown occurs
Mechanical vibration Measurement and evaluation of machine Annex C informative Guidelines for specification of evaluation criteria for vibration measured on nonrotating parts and rotating shafts vibration standards For some machines measurements made on nonrotating parts are sufficient to characterize adequately
