【摘要】：针对建材受热温度与可燃性的关系建模研究中,由于温度的高低和湿度的大小使可燃性指数受到干扰。采用传统的算法进行建模时,没有考虑这种干扰与建材可燃性信息存在的关系,仅仅以固定权值进行描述,造成建模精确度低,实用性差。提出基于元细胞算法的建材受热温度与可燃性的关系建模方法。依据建材周围环境中温度与湿度等因素,分析建材可燃烧的特性,融合三维元细胞自动机对建材受热温度的变化趋势;利用能体现建材受热、温度变化、可燃点的基本特征参数建立建材受热温度与可燃性指数的关系模型。仿真结果表明,基于元细胞算法的建材受热温度与可燃性的关系建模方法精确度高,适用性强。
[Abstract]:In the modeling of the relationship between heating temperature and flammability of building materials, the flammability index is disturbed by the temperature and humidity. When the traditional algorithm is used to model the model, the relationship between the interference and the flammability information of building materials is not considered, and only the fixed weight is used to describe the model, which results in low modeling accuracy and poor practicability. A method of modeling the relationship between heating temperature and flammability of building materials based on cell algorithm is proposed. According to the factors such as temperature and humidity in the surrounding environment of building materials, this paper analyzes the combustible characteristics of building materials, fuses the changing trend of three-dimensional cellular automata to the heating temperature of building materials, and makes use of the energy to reflect the heating and temperature changes of building materials. The relationship between heating temperature and flammability index of building materials is established by the basic characteristic parameters of combustible point. The simulation results show that the modeling method based on the metacellular algorithm for the relationship between heating temperature and flammability of building materials is of high accuracy and applicability.
