Aiming at the layout problem of control points during the multipoint control random vibration test, two methods to choose the control points are discussed. Firstly, the necessity of choosing the layout scheme for control points is explained, and then two methods are summcrized, namely analogy method and test method, to determine the layout scheme of control points.Besides, the merits and applied occasion of the two methods are analyzed and discussed. Finally, two examples are presented to show the application situation and the effect of the two methods.
