Product Description
Description:
KRD20 bump test machine is a fully automatic pneumatic lift vertical bump test system. It is applicable to measure and determine the bump resistance of components, equipments 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:
- Advanced drive system: full pneumatic drive, greatly improving the efficiency of bump test
- Humanized operation: the bump velocity can be controlled by adjusting the air flow, which is convenient to adjust the bump velocity
- Use 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 one-piece cast aluminum alloy platform, high-quality base, 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 reliability, and better bump waveform
System composition:
System table composition
The system composition diagram of the bump test machine mainly includes test machine table, control measuring instrument, acceleration sensor, computer, printer, etc.
The bump test machine consists of three parts: the body of the bump test machine, the gas system and the control and measurement system.
Pneumatic Bump Tester Table
The system composition diagram of the bump test machine mainly includes test machine table, control measuring instrument, air system acceleration sensor, waveform generator, etc.
KRD20 pneumatic bump testing table is composed of working table, shock plate, base, air cylinder, guide rod, sensor, damper etc. The system block diagram is shown in following.
Pneumatic bump test machine is a pneumatic lift vertical bump tester. The air pressure release system is adopted to increase the bump energy and achieve a greater end-of-bump velocity, thereby achieving the specified bump acceleration.
Waveform Generators
The pneumatic bump 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.
Measurement And Control Instrument
The control measurement analyzer mainly controls the lifting of the bump table, the acquisition and processing of the height signal and the signal acquisition and processing of the acceleration sensor. Considering the needs of the system environment and convenient operation, the computer is directly connected to the measuring and controlling instrument, and the platform is connected to the controller. The controller is shown in following figure.Shock Amplifier
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.
