Reliability Analysis of Kinematics Accuracy for a Metamorphic Palletizing Robot Mechanism

Abstract

∗Metamorphic mechanisms have many configurations, which has the potential to be widely used in engineering. Kinematics reliability is the key to ensure their normal operation in practical application. In this paper, according to the 2-DOF open loop mechanism, the metamorphic palletizing robot mechanism is presented. Moreover, the kinematics analysis is carried out. Based on this, the failure function of kinematics accuracy failure is obtained. Then, the reliability model is established. Monte Carlo method based on neural network is used to calculate reliability of this model. In this method, a large number of data can be fitted from a limited set of data. The Monte Carlo method is applied to calculate the reliability on this basis in addition. The calculation process of the kinematics reliability of the mechanism is given in an example. The work of this paper provides a reference for the reliability research of metamorphic mechanism.
