Packaging materials Paper Testing Equipments buffer intensity

1 ,  the buffer material testing machine system

According to GB8167-87 ,  GB8171  " dynamic cushioning material for packingcompression test method "  test buffer performance of cushioning materials

2 ,  system structure :

3 ,  the buffer material testing machine system :

 ( 1 )  using the speed detector developed ,  determination of instantaneous velocityat the start of the precise impact

 ( 2 )  any circumstances can reliable acquisition impact acceleration time signal

 ( 3 )  to filter the acceleration signal provides a variety of FIR digital filter ,  the signalwithout distortion ,  the performance for the mechanics of cushioning materials , development of new cushioning material is particularly important

 ( 4 )  in linear or logarithmic display maximum acceleration static stress ,  cushioningcoefficientmaximum stress and dynamic stress - strain curve

 ( 5 )  provide a variety of curve fitting program ,  especially the manual fitting ,  so that the more you work

 ( 6 )  full automatic file name ,  without human intervention

 ( 7 )  a graph line ,  so you can put the number of curves in a linear or logarithmiccoordinates in a picture ,  for study ,  mechanical properties ,  comparison of variousmaterials with different situations when the buffer performance provides a convenient

 ( 8 )  even if the interrupt test ,  data will be stored ,  subsequent tests without starting from scratch

Press the button 

( 9 )  test report ,  test report automatically to the Word version of experimental data .

Application of 4 ,  buffer material testing machine system :

 ( 1 )  the maximum acceleration test of static stress curve or buffer coefficientstress curve of cushioning packaging design

 ( 2 )  the development of new cushioning material ,  using the shock accelerationtest to get the time curve ,  dynamic stress-strain curve ,  power curve or buffer coefficient maximum stress on the mechanical properties of material force curve of maximum acceleration static ,  cushioning performance and their relationship .

 ( 3 )  the maximum acceleration curve of cushioning material production factory to provide cushioning materials of various grades ,  different density in various test conditions and buffer coefficient curve

 ( 4 )  the original transport packaging cushioning performance analysis and improvement ,  design and improvement of cushioning packaging

Rapid test method of buffer material testing machine

By making it freely falling weight impact specimen ,  obtained directly ,  cushion coefficient stress curve of dynamic material from the impact accelerationwaveform .  As everyone knows ,  the buffer performance of cushioning materialscan be used to cushion coefficient stress  ( or strain )  curve description .  It has two kinds of test methods ,  namely static compression tests and dynamic compression test method .  The former is in the pressure testing machine .  The specimens were compressed ,   ( for its performance by the pressure - deformation curve of 1 )  .  Its advantage is to sample a small number of simple ,  test equipment ,  test time is short ,  low cost
