KRD20 PNEUMATIC BUMP TEST MACHINE
KRD20 bump test machineis a fully automatic pneumatic lift vertical bump test system. It is applicable to measure and determine the bump resistance of components, pieces of equipment, and other electro-technical product during transportation or in use. It provides a standard procedure for determining the ability of a specimen to withstand specified resistance of bump. The bump test may also be used as a means of determining the satisfactory design of a specimen in terms of structural integrity. It is mainly a standard pulse-shaped repetitive shock to a specimen on a bump tester, with a specified peak acceleration and duration.
FEATURES OF KRD20 PNEUMATIC BUMP TEST MACHINE
Advanced drive system: full pneumatic drive, greatly improving the efficiency of bump test
Humanized operation: the bump velocity can be controlled by adjusting the airflow, which is convenient to adjust the bump velocity
Use the automatic photoelectric switch to measure lifting height, high bump repeatability
The worktable has a high natural frequency, and there is small high-frequency clutter during bump
The use of a one-piece cast aluminum alloy platform, high-quality base, and high-strength chrome-plated guide rail, so that the product has sufficient rigidity and long service life
Optimized design system, which can greatly reduce the high-frequency clutter generated during bump, make the bump waveform smoother, higher reliable, and better bump waveform
TABLE OF KRD20 PNEUMATIC BUMP TEST MACHINE
The system composition diagram of the bump test equipmentmainly includes a test machine table, control measuring instrument, air system acceleration sensor, waveform generator, etc.
KRD20 pneumatic bump testing table is composed of a working table, shock plate, base, air cylinder, guide rod, sensor, damper, etc. The system block diagram is shown in the following.
A pneumatic pump test machine is a pneumatic lift vertical bump tester. The air pressure release system is adopted to increase the bumping energy and achieve a greater end-of-bump velocity, thereby achieving the specified bump acceleration.
DUAL MASS SHOCK AMPLIFIER OF KRD20 PNEUMATIC BUMP TEST MACHINE
The shock amplifier is a device that uses the rebound energy of the ordinary impact shock table to realize the opposite impact between the servo table and the seat on the amplifier so that the impact acceleration is multiplied.
WAVEFORM GENERATORS OF KRD20 PNEUMATIC BUMP TEST MACHINE
The pneumatic pump test machine is equipped with a fixed pulse width half-sine wave generator. The half-sine wave generator is mainly made of engineering rubber (considering the stiffness and cohesive force of rubber). The waveform generator is cylindrical and generally designed in several different thicknesses. Different thicknesses are connected in series to form multiple stiffnesses to achieve different bump pulse widths.
