Real-time multi-body co-simulation model of a veneer peeling lathe

This paper introduces a real-time co-simulation model for the prediction of the dynamics behavior of a veneer peeling lathe machine. The real-time co-simulation model introduced is described in the framework of multi-body system dynamics. It makes use of a co-simulation procedure in which a semi-recursive multi-body approach is combined with a detailed contact description. In the employed closed-loop semi-recursive method, the constraint conditions are carried out in the system motion differential equations via the augmented Lagrangian method. A contact procedure is presented to describe the contact between the wooden log and the cutting blade and the support rollers. The results obtained by the co-simulation are compared against those experimentally measured through a peeling lathe machine in operation and an approximate finite element model of the peeling process. According to the numerical results, it is concluded that the real-time simulation model can predict dynamic performance of the complicated system of a veneer peeling lathe in real-time. Solvability of equations of motion makes the introduced model suitable to be utilized in a number of product process purposes such as marketing, training and product development projects.
