To study a new theory of complete probability method of antiresonance vibration reliability design, based on the conventional vibration design theory and interference theory of reliability, complete probability method models were made, and solutions were given by numerical integral. Equations of calculating reliability of 4 types and 7 different kinds of working and critical frequencies interferences were derived, and effectualness of them was verified. For the low reliability, the distribution type would make not much difference to the reliability. It is possible that the normal distribution is used to take the place of other distributions. But for the high reliability, the distribution type would make a great difference to the value of reliability.
