TECHNICAL PARAMETER DETERMINATION FOR LINE HEATING BASED ON SURFACE SUPERPOSITION

摘要

An algorithm of technical parameter determination for line heating based on surface superposition is developed. Firstly, factors affecting deformation of line heating are divided into two categories: fixed parameters and control parameters, and the technical parameters for line heating are defined as position and control parameters of every heating line. Then, a multiple heating lines deformation superposition algorithm is derived under the given conditions such as configuration of plate, positions, fixed and control parameters of heating lines. Based on this algorithm, a non-linear goal-programming model for technical parameter determination of line heating is set up with minimum total acetylene consumption and the minimum total processing time as the objective constraints. Furthermore, a simplified form and solution to the model are proposed.
