Application
Used to control the rise or fall of the test bench table (ie, adjust the drop height). When the operation starts, it is the "automatic" control state, and the system automatically controls the test bench table drop height according to the set impact acceleration value (the "auto" indicator turns red). When you hit "up" or "down", the test bench height will rise or fall (the "up" or "down" indicator turns red and the "auto" indicator turns gray). If you press "up" or "down", the test bench will stop changing (the "up" or "down" indicator will turn gray). If you still want to restore the "automatic" control, then hit "automatic". "Rise", "Descent", "Auto" must be effective when the system is running, and the operation is invalid when the system is stopped.
Impact platform working principle The SBM impact control measuring instrument is operated to start the AC motor, and the lifting device is driven by the transmission chain to raise the table top (including the test piece) to a preset height, and then the lifting device is separated from the table top (test piece) by the selecting device. The table top (test piece) becomes a free fall impact on the cushion, resulting in a half-sine shock pulse. Adjusting the height of the table can change the acceleration value of the shock pulse; changing the material of the cushion and the thickness of the cushion can change The duration of the shock pulse.
Preparation 1-1 Connect the computer, interface box, monitor, keyboard, and impact test bench with a dedicated cable (our company has already connected it during installation and commissioning). 1-2 Turn on the power supply to the computer, the interface box, and the monitor with a dedicated power cord. 1-3 Wipe the bonding surface of the accelerometer and the test bench with acetone, and rigidly bond the accelerometer to the test bench with 502 glue (also available with screws or other connection methods). 1-4 After the acceleration sensor is firmly bonded to the test bench, it is firmly connected by a dedicated cable (low noise cable) (one end is connected to the acceleration sensor output port, and the other end is connected to the rear panel "sensor input socket").
