Embodiment Construction

[0110] Such as figure 1 As shown, a hybrid fiber composite explosion-proof tank configuration design method, including the following steps:

[0111] S1. Establish an initial explosion-proof tank configuration that meets the preset conditions;

[0112] Design background: The explosive equivalent is 4 kg of TNT mass, and the initial explosion-proof tank configuration is as follows:

[0113] The initial configuration of the explosion-proof tank is a cylindrical container, and the length of the bus bar of the cylindrical container is set to 0.8m, the diameter is 0.6m, and the diameter of the holes at both ends is 0.18m; the fiber volume content in the composite material is 60%, and the curing degree is >85%. The fiber thickness of each layer of the straight section is 0.2mm; the mass of the straight section is limited to 90kg, the elastic modulus is >150GPa, and the composite fiber mixing ratio is set to Kevlar 49 fiber: carbon fiber = 45%: 55%.

[0114] Establish an ABAQUS mode...

Abstract

The invention discloses a configuration design method for an anti-explosion container made of a hybrid fiber composite material, and a configuration evaluation criteria. A created energy absorptivity criteria provides a judgment method for optimizing of the anti-explosion container made of the hybrid fiber composite material, and provides an optimal configuration of the anti-explosion container. The configuration design method is characterized by comprising the following steps: constructing an initial anti-explosion container configuration meeting preset conditions; parameterizing an anti-explosion container geometrical configuration; optimizing the initial anti-explosion container configuration according to a multi-island genetic algorithm to obtain a locally optimal solution area of the initial anti-explosion container configuration; carrying out globally optimal solution of the initial anti-explosion container configuration according to a gradient algorithm; evaluating an optimal anti-explosion container configuration according to energy absorptivity. The configuration design method has the advantages that the initial configuration of the anti-explosion container is optimized, so as to provide the optimal configuration; the defects that the conventional metal anti-explosion container is heavy and poor in energy absorptivity are overcome, and the configuration of the anti-explosion container is improved by changing the thickness of a paved layer, so that the energy absorptivity of the anti-explosion container is greatly improved, and engineering safety is guaranteed.

Description

technical field [0001] The invention relates to the field of safety design of explosion-proof tanks, in particular to a configuration design method for explosion-proof tanks made of hybrid fiber composite materials. Background technique [0002] Explosion-proof tanks are generally used in explosion-proof places such as railway stations, subways, courts, museums, stadiums, exhibition centers, airports, customs, ports, embassies, etc., mainly to ensure the safety of personnel and maintain the order of the place. Nowadays, the materials used in the manufacture of explosion-proof tanks are metal or concrete, and there are no composite materials, let alone hybrid fiber composite materials. The explosion-proof tank made of hybrid fiber composite material has a wider application space than the traditional metal explosion-proof tank due to its light weight, low price and easy movement. Creating and optimizing the configuration of explosion-proof tanks made of hybrid fiber composite...
