Abstract

Reliability-based design optimization (RBDO) plays an important role in optimal design because this optimal design method is achieved taking into account uncertainty and is very reliable. This paper applies the RBDO approach to analyze and design the CNC router structure for machining wood materials. With the desired reliability R*, the inverse reliability analysis method is utilized to transform the RBDO problem into a deterministic optimization problem. Monte Carlo simulation (MCS) is utilized to analyze the reliability of the machine structure after optimal design in accordance with the stiffness and strength criteria. The reliability analysis results, according to the MCS method, are compared with the desired reliability R* of the body structure. The obtained findings highlighted that body structure after optimized design according to the RDBO method is satisfactory.
