The above-mentioned contents briefly introduce a design method for lightweight of the domain controller housing structure of the present invention, and detailed descriptions will be given below with respect to the specific contents.
In an alternative embodiment of the present invention, the method for calculating the volumetric strain of the target surface according to the maximum stress suffered by the target surface and the design material of the target surface specifically comprises the following steps:
(1) Determining the bulk modulus of the target surface according to the design material of the target surface;
Specifically, the design material of the target surface is known, and its bulk modulus is known.
(2) The volume strain of the target surface is calculated according to a volume strain calculation formula v=σ/E, wherein V represents the volume strain of the target surface, σ represents the maximum stress to which the target surface is subjected, and E represents the volume modulus of the target surface.
In an alternative embodiment of the present invention, the method for calculating the initial volume design value of the target surface according to the volume strain of the target surface and the volume deformation of the target surface under the maximum stress specifically comprises the following steps:
And calculating an initial volume design value of the target surface according to an initial volume design value calculation formula v1=Δv/V, wherein V1 represents the initial volume design value of the target surface, Δv represents the volume deformation of the target surface under the maximum stress, and V represents the volume strain of the target surface.
In an alternative embodiment of the present invention, the basic thickness threshold of the target surface is calculated according to the initial volume design value of the target surface and the structural dimension of the target surface, and specifically includes the following steps:
The basic thickness threshold of the target surface is calculated according to a thickness calculation formula h=v1/(l×w), where H represents the basic thickness threshold of the target surface, V1 represents an initial volume design value of the target surface, L represents a length in the structural dimension of the target surface, and W represents a width in the structural dimension of the target surface.
Specifically, the basic thickness threshold of the target surface is the destroyed limit thickness t1 of the target surface under the preset mechanical experiment condition, namely the basic thickness threshold t1 of the target surface with the design thickness t being more than or equal to the design thickness t is required to be met, and the structural design can be met, namely the basic thickness threshold t1 of the target surface can meet the requirement.
In an alternative embodiment of the present invention, the determining the target thickness value of the target surface according to the basic thickness threshold and the preset thickness threshold of the target surface specifically includes the following steps:
And taking the maximum value of the basic thickness threshold value and the preset thickness threshold value of the target surface as the target thickness value of the target surface.
Specifically, the preset thickness threshold is 1.5mm. The inventor obtains the value of the product process forming coefficient k according to the rule of die casting process forming, and the value is related to the thickness t and the die drawing angle epsilon, and specifically comprises the following steps: k=epsilon/t. In the die casting industry, the drawing angle epsilon is 1.5 degrees at minimum, and the feasibility of molding is high when the product process molding coefficient k is more than or equal to 1, so that the thickness tmax is 1.5mm (the drawing angle is 1.5 degrees, and the thickness tmax is 1.5, k can be more than or equal to 1), and t is more than or equal to 1.5mm, so that 1.5 is a preset thickness threshold; epsilon is a design input value, and the input range is less than epsilon and less than 90 DEG at 1.5 DEG.
That is, the thickness t is not less than 1.5mm, and the thickness t is not less than the basic thickness threshold t1 of the target surface, the final thickness t (i.e., the target thickness value) is not less than 1.5mm and t1, and the thickness t (i.e., the target thickness value) is not less than 1.5mm and t1 from the aspect of weight reduction.
In an alternative embodiment of the present invention, the determining the target draft angle of the target surface according to the target thickness value of the target surface specifically includes the following steps:
and taking the target thickness value of the target surface as the target draft angle of the target surface.
Specifically, the molding is performed only when the product process molding coefficient k is not less than 1, and the smaller the draft angle is, the lighter the weight of the structural member of the domain controller is from the aspect of weight reduction after the target thickness value of the target surface is obtained, so that the designed draft angle needs to be minimized. When k=1, the draft angle is the smallest, and at this time, the target thickness value of the target surface is equal to the target draft angle of the target surface, that is, when the target thickness value of the target surface is equal to the target draft angle of the target surface (i.e., when k=1), the weight of the product is the smallest, so the target thickness value of the target surface is taken as the target draft angle of the target surface.
In an alternative embodiment of the invention, the mechanical test conditions include at least: drop test conditions, impact test conditions, vibration test conditions.
The design method for the light-weight shell structure of the domain controller has the following advantages:
(1) The invention can carry out weight reduction design on different strength conditions (different mechanical conditions given by customers) of different positions (such as an upper shell or a lower shell) of the domain controller in the design stage;
(2) Partial weight reduction (such as weight reduction of the upper shell only) can be performed according to a weight reduction method;
(3) The product reduces the design redundancy structure (avoiding the excessive thickness of local design, specifically, taking the target thickness value as the target draft angle after obtaining the target thickness value, namely, the draft angle is minimum, and the product weight is reduced to the maximum extent), thereby reducing the overall quality of the product, and realizing the product cost reduction.
(4) Different weight-reduction thicknesses can be calculated according to different maximum stresses of multiple surfaces of the product.
