Squeak & Rattle Shaker Systems for vertical excitation

Depending on the size and weight of the components to be tested and the required acceleration levels MB offers Squeak & Rattle shaker systems of various sizes. All MB Squeak & Rattle shaker systems are extremely quiet and fulfill the strict operating noise requirements of typical Squeak &Rattle test specifications. Within the system specifications all Squeak & Rattle shaker systems can also be used for durability and aging tests. The following examples provide an overview of typical system configurations for excitation of small parts, medium- and large sized components in vertical direction. Alternative system configurations according to specific requirements are possible at any time.

 

Squeak & Rattle shaker systems for small parts and components (Ashtray, cupholder, radio etc.)

Vibrating table for small components

 

  • Uses a MB Energizer RED Squeak &Rattle Shaker
  • Extremely quiet operation <28 dB(A) when simulating typical S&R test tracks *
  • Typical Operating Noise fulfills requirements of Noise Rating Curve NR18 **
  • Maximum force:
    • SINE: 500N peak (continuous-duty)
    • RANDOM: 350N RMS
    • TIME HISTORY / SHOCK (instantaneous): 1000N peak
  • Can be operated in uncooled mode up to 50% of maximum force
  • Air spring load support to support static test loads of up to 20kg
  • Additional guidance of the vibrating table by external flexures avoids unacceptable lateral forces and bending moments on the suspension of the voice coil
  • Frequency range: 2 Hz to 2000Hz
  • Max displacement: 38mm peak-peak
  • Max. velocity: 1.5 m / s
  • Power amplifier MB500VI with adjustable thresholds ​​for max. output voltage and output current to protect the system from electrical overload
  • Optional trunnion base allows rotation if the S&R Energizer to ±90° from vertical
  • Optional Horizontal Moving Table (HMT)
  • Optional temperature controller & shut down
  • Optional Chamber Readiness Kit enables use inside environmental chamber from -40°C to +60°C including humidity
