The optimum design of the prefabricated components is the foundation of energy saving, environmental protection and maximum life cycle value of building products. In this paper, the numerical analysis and optimum design of a new type of lightweight partition board are carried out to meet the requirements of mechanical properties, thermal transferring and simple prefabrication. Based on the standard partition board and numerical analysis, the circular cross section type partition board is modified to the elliptical cross section type. The numerical analysis is carried out to compare two types of partition plates (circular section and elliptical cross section) with respect to the mechanical performance and heat transfer performance. Among them, load modes which may occur in construction and service stage, are used to study the mechanical properties, effect of stress concentration and overall partition board stiffness. The heat transfer performance analysis is also done to compare the cooling time for the two kinds of partition boards in the confined space. The numerical analysis results show that the elliptical partition board not only reduces its weight by 5.6%, but also reduces the stress concentration effect of the hole to a certain extent. The thermal transferring performance of the elliptical partition board is 12% higher than that of the circular partition plate.
