What does the anti-vibration energy storage system include

To verify that components are sufficiently protected against vibration damage, we must first set ourselves a standard of acceptability. Many of us will have seen the effects of excessive vibration on equipment, ranging from abnormal wear and loosened fixings to actual breakage of components.

Many of us will have seen the effects of excessive vibration on equipment, ranging from abnormal wear and loosened fixings to actual breakage of components. Mechanical equipment can be made immune by traditional methods such as locking components down with extra fixings or by deliberate isolation of sensitive areas using anti-vibration mountings.

Where resonances are found, the standard suggests a dwell time of 10 min, 30 min, 90 min or one hour. IEC 60068-2-6: 2008 does not prescribe exact vibration intensity levels and a number of sweep cycles but gives examples as shown in Table 1, derived from the standard. Cross-over frequency is set to be between 58Hz and 62Hz.

Today, vehicles are the prime example of a relatively hostile environment for shock and vibration in which we are packing all kinds of electronics, in everything from high power electric motor control through automated driver assistance systems to infotainment.

The high vibration specification of these parts is complemented by automotive AEC-Q200 compliance and high endurance ratings, typically 10,000 hours at 105°C, 4000 hours at 125°C and 2000 hours at 145°C depending on the series

The improvement in performance is dramatic with the vibration-proof types able to withstand 294m/s2 (30g) and a peak to peak displacement of 5mm with vibration excitation from 5 to 2000Hz. Tests were performed in the X, Y, and Z axes for two hours each with no failure.
