Correspondence of shock and sine acceleration values
What is the ratio of shock acceleration (it is not always specified) and sine acceleration?
How can Newton’s 2-nd law be applied in the case if there is no correlation between the specified 200N value (for shaker system TV 51120) and the maximal shaker stand acceleration value of 98m/s2?
Should I use the formula 200=98×[suspension weight]?
What does the effective dynamic mass of 0,23 kg then stand for?
Relation of sine signal maximum acceleration value and the one of shock pulse is determined by shaker system structure and may correspond to the range of 20-300%. In the case if the shaker system manufacturer has not explicitly specified the acceleration and force values for shock vibration tests perrfomance, then one can use the values specified for sinusoidal vibration tests perfomance.
TV 51120 technical specifications contain the following information: «Effective moving mass – 0.23 kg», which means that Newton’s 2-nd law is observed, however the effective moving mass value still has to be determined.
