BW-MST-E5000

MECHANICAL SHOCK TEST SYSTEM

Modern electronic devices must endure the effects of repetitive mechanical shocks and sustain operation to achieve customer satisfaction. The BW-MST-E5000 is designed to produce these high impact shocks associated with dropping a device.

Precise control of the shock amplitude is provided by the PC based controller which utilizes a high performance multifunction analog, digital and timing input/output and data acquisition board with custom software running in a Windows environment. The data storage capacity can be used for careful analysis and to generate test reports.

The Mechanical Shock Tower develops the kinetic energy electromagnetically. An iron core "bullet" is attracted to the magnetic core of the solenoid by the dense magnetic field that is created as current flows through the field coil of the shock tower. As the bullet is drawn into the center of the magnetic field the acceleration increases exponentially as the gap reduces to zero on impact causing the high impact shock. The properties of the impacting materials determine the pulse shape and duration. The RTV strike pads supplied with the system provide half sine pulses of 2.0 - 0.5 millisecond durations and an aluminum for <0.3 millisecond.
