Identification of Compliant Contact Force Parameters in Multibody Systems Based on the Neural Network Approach Related to Municipal Property Damages

Abstract

Abstract:In this paper, a new approach for identification of the compliant contact parameters model in multibody systems simulation using a neural network algorithm is presented. Based on the training and testing the network for some input and output data sets, a general framework is established for identification of these parameters. For this purpose, first, the literature devoted to the identification of contact parameters using analytical approaches and methods based on the neural network is reviewed in brief. Next, the proposed approach is outlined. Finally, considering a classical example of contact of two bodies, the proposed approach is applied for verification of the obtained results.

Nonlinear phenomena of contact in multibody systems dynamics: a review

“…numerical calculations use the value n ¼ 1:5 for metallic materials, changing it when working with other materials such as glass or different polymers [101,123,124]. This must not be confused with the Hertzian model just described.…”
