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