Product Multibody Dynamics Analysis for Low Carbon Footprint

Abstract With the increasingly serious global climate problem, the low-carbon design of products aiming at reducing the carbon emission in the life cycle has gradually become an important direction of sustainable manufacturing. The optimization design of product structure is one of the important means to realize the low-carbon operation of product structure. Therefore, how to carry out the low-carbon optimization design of product is the focus of this paper. The dynamics analysis of product digital model can provide effective help for product structure optimization. It provides simulation results of the whole life cycle of products by establishing digital virtual prototyping model of complex system based on multi-body dynamics theory. In this paper, a new framework of low carbon manufacturing is constructed, a digital model of 2000 tons offshore crane is constructed by using virtual prototype technology and dynamic load analysis is carried out. Based on the dynamic simulation and load analysis of the offshore platform crane, the low-carbon optimization design of the offshore platform pile leg is carried out, and the carbon emission of the whole life cycle is optimized, and the feasibility of the scheme is verified.
