METHOD TESTING SOT FURNITURE FOR STRENGTH UNDER ACTION OF IMPACT LOAD

摘要

FIELD: testing. SUBSTANCE: method is realized by delivering blows by sequential throwing of weight from definite height on to various points of surface of tested sample placed immobile. Points of loading on surface that is meant for sitting or lying of man are established in random way for each cycle of delivering of blows. In process of testing height of throwing of weight with reference to points of loading is changed in specified interval within the bounds of which its value for each cycle of delivering of blows is established in random way. Time period between cycles of delivering blows changes in specified interval within limits of which its value for each of two sequential cycles of delivering of blows is established in random way. Densities of distribution of collection of values of coordinates of points of loading, heights of throwing of loads and time periods between sequential cycles of loading are subject to known laws of distribution of random values. EFFECT: enhanced authenticity of testing results. 5 cl, 2 dwg
