The Composition Kinematic Reliability of Path Mechanism

Article Preview

Abstract:

Normally, the kinematic reliability of the path mechanism is the probability of the coordinate components error of position vector of couple point satisfied its allowable error in last literature. Sometimes, it would have more valuable that we study the composition motion reliability. In this work, we present a composition kinematic reliability model for path mechanism, which is a linear combination of non-central chi-square distribution. Then a quadratic form method is used to calculate the failure probability of path mechanism.
