Accelerometer and data acquisition system specification

Click For Summary
SUMMARY

The discussion centers on the specification of accelerometers for a Mechanical Engineering project focused on testing head restraint performance in vehicles. The student is exploring Piezoelectric accelerometers due to their suitability for measuring dynamic accelerations. The project requires adherence to channel frequency class 600, prompting inquiries about relevant specifications and values on accelerometer data sheets. Additionally, the student seeks resources to better understand channel frequency class and its implications for transducer selection.

PREREQUISITES
  • Understanding of Piezoelectric accelerometers
  • Familiarity with channel frequency classes, specifically class 600
  • Knowledge of data acquisition systems
  • Basic principles of dynamic acceleration measurement
NEXT STEPS
  • Research specifications for Piezoelectric accelerometers
  • Study the implications of channel frequency class 600 on data acquisition
  • Explore resources on dynamic acceleration measurement techniques
  • Review data sheets for accelerometers to identify key specifications
USEFUL FOR

Mechanical engineering students, electronics engineers, and professionals involved in automotive safety testing who require knowledge on accelerometer selection and data acquisition systems.

Hi,

I'm a Mechanical Engineering student and the voodoo that is electronics/ electrical engineering baffles me.

However a portion of my final year project requires me to specify certain transducers and a data acquisition system.

At the minute I am trying to specify an accelerometer.

I'm either correctly or incorrectly looking at Piezoelectric accelerometers as my research has lead me to believe that they are the way to go when looking at dynamic accelerations (the project is a piece of apparatus to test the performance of head restraints in vehicles).

The guide lines I have to stick to are that the channel has to be channel frequency class 600.

Can anybody point me in the right direction as to what values I need to be interested in on the data sheets for accelerometers?

Many thanks, to anyone who can spare me a bit of wisdom.

Sorry to bump this but if no one has any ideas, can someone suggest a book or resource that might explain what channel frequency class is and how it will affect the specification of transducers?
 
You may want to ask the person that posed the problem what channel class 600 means.
