Abstract

The present invention discloses a foam asphalt mixture stirring device structure design and optimization analysis method, and is applicable to the technical field of foam asphalt. A counteraction of a foam asphalt mixture pseudo-fluid in numerical simulation of CFD software on a structure is loaded into a stirring structure without a data loss by means of an interface between an ANSYS Workbench platform and the CFD software, and optimization analysis is performed on the structure by means of an ANSYS Workbench optimization tool, so that a seamless connection is performed on driving of a stirring blade, stirring of a mixture pseudo-flow-field and a counteraction of the pseudo-flow-field on the stirring blade, so as to optimize and analyze a structure of a foam asphalt mixture stirring device, and therefore, an effective and rapid design method for the stirring device is provided, and reliability of a stirring device analysis result is improved.

Description

Technical field: [0001] The invention relates to an analysis method for structural design and optimization of foamed asphalt mixture mixing equipment, which is applicable to the technical field of foamed asphalt. Background technique: [0002] In the field of modern pavement construction engineering, single asphalt mixing equipment has gradually been unable to meet the requirements of construction and production. Foamed asphalt has incomparable advantages over ordinary asphalt, and can fundamentally solve the shortcomings of asphalt concrete such as rutting resistance, temperature crack resistance, fatigue damage resistance, and weak loosening resistance, and foamed asphalt is energy-saving and environmentally friendly. High, so foamed asphalt is widely used in road construction occasions, and foamed asphalt-related technologies have also attracted extensive attention in the field of road construction machinery. [0003] Foamed asphalt mixture mixing equipment is to mix coa...
