Description

Technical Field

[0001] This invention relates to the field of automotive simulation technology, and in particular to a simulation analysis method and apparatus for the influence of brake disc thermal radiation on the thermal deformation of dust discs. Background Technology

[0002] Disc brakes are now widely used in passenger vehicles. During disc braking, brake fluid presses the friction pads tightly against the brake disc to generate braking torque, thereby slowing the vehicle down.

This heat dissipation causes the brake disc temperature to rise rapidly, reaching temperatures ranging from 300°C to 800°C. If this heat cannot dissipate quickly, it will radiate to the brake disc, causing thermal deformation and other problems, affecting the vehicle's driving comfort and safety. Summary of the Invention

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following describes, with reference to the accompanying drawings, a simulation analysis method and apparatus for the influence of brake disc thermal radiation on dust disc thermal deformation according to an embodiment of the present invention.

[0020] Figure 1 This is a flowchart illustrating a simulation analysis method for the influence of brake disc thermal radiation on dust disc thermal deformation, provided in an embodiment of the present invention.

[0021] like Figure 1 As shown, the simulation analysis method for the influence of brake disc thermal radiation on dust disc thermal deformation includes the following steps: In step S101, a finite element model of the target brake disc is established.

[0022] In some embodiments, establishing a finite element model of the target brake disc includes: The outer surface of the target brake disc is divided into the friction ring surface, the ventilation rib surface, and the disc cap surface. Solid meshes were generated on the surfaces of the friction ring, ventilation ribs, and disc cap, respectively. Extract the surface mesh from the dust baffle in the solid mesh, and establish a finite element model based on the surface mesh in the dust baffle.

[0023] In actual implementation, such as Figure 2 As shown, the predefined analysis conditions are: initial brake disc temperature 100℃, initial vehicle speed 100km / h, final speed 0km / h, braking deceleration 1.0g, 10 cycles, and cooling air speed 20km / h, as shown in Table 1 below.

[0024] Table 1. Working conditions for thermal stress analysis of brake discs

[0025] Predefined material properties: The material properties of brake discs and dust discs include elastic modulus, Poisson's ratio, density, and the changes of brake disc thermal conductivity, specific heat capacity, and coefficient of thermal expansion with temperature, as shown in Tables 2 and 3.

[0026] Table 2 Brake Disc Material Properties

[0027] Table 3 Material Properties of Dust Baffles

[0028] Furthermore, such as Figure 3 As shown, the outer surface of the brake disc is divided into a friction ring surface 304, a ventilation rib surface 303, and a disc cap surface 302. A solid mesh is then generated based on the surface mesh. The surface mesh consists of 2mm elements with a thickness of 0.01mm, while the solid mesh is 3mm in size. A surface mesh for the dust baffle 301 is extracted and generated from the solid mesh, with the thickness set to the actual dust baffle thickness and a mesh size of 2mm, to obtain the finite element model. This process allows for the rapid application of heat flux loads and heat exchange boundary conditions to the various thin film surfaces of the brake disc, while minimizing the impact on the calculation results.

[0029] In step S102, the thermal deformation of the target brake disc on the dust baffle is calculated based on the finite element model.

[0030] In some embodiments, calculating the thermal deformation of the target brake disc on the dust baffle based on a finite element model includes: The transient uncoupled thermal radiation analysis method of ABAQUS was used to calculate the thermal radiation temperature field of the target brake disc on the dust baffle based on the finite element model. The ABAQUS implicit analysis method is used to calculate the thermal deformation of the target brake disc on the dust baffle based on the thermal radiation temperature field.

[0031] In actual implementation, a physical model is set up: the ABAQUS transient uncoupled thermal radiation analysis method is used to calculate the thermal radiation temperature field of the brake disc on the dust baffle, and then the ABAQUS implicit analysis method is used to calculate the thermal deformation of the dust baffle.

[0032] Among them, thermal radiation analysis follows the Stefan-Boltzmann law and is calculated according to formula (1): (1) In the formula, The heat flux radiated outward by an object is measured in watts per square meter (W / m²). 2 ); Since the emissivity of an object usually varies depending on the surface condition and temperature of the material, the emissivity of the cast iron brake disc after oxidation or high temperature in this embodiment of the invention is 0.6, and the emissivity of the aluminum dust shield disc after oxidation is 0.4. It is the Stefan-Boltzmann constant, approximately ; The surface area is the radiating area, and the unit is square meters (m²). 2 ); The shape factor is from radiation surface 1 to radiation surface 2. The absolute temperature of radiating surface 1 is expressed in °C. The absolute temperature of radiating surface 2 is expressed in °C.

[0033] Set load conditions: such as Figure 4 As shown, the *DFLUX command is used to apply a heat source to the surface of the brake disc friction ring in the thermal radiation analysis. The calculation of the heat source takes into account the vehicle braking force distribution coefficient, the total mass under full load, the braking deceleration and the wheel speed, and is calculated according to formula (2): (2) In the formula, For heat sources, the unit is watt (W); This refers to the braking force distribution coefficient; The total mass at full load is expressed in kilograms (kg). Braking deceleration, measured in meters per square second (m / s²) 2 ); The vehicle speed is expressed in meters per second (m / s).

[0034] Furthermore, the *FILM command is used in the thermal radiation analysis to define the heat exchange coefficients of the brake disc friction ring surface, ventilation rib surface, and disc cap surface at different vehicle speeds. Heat exchange coefficients are defined on each surface of the brake disc and dust shield, such as... Figure 5 As shown.

[0035] Set boundary conditions: Import the heat source and heat exchange coefficient into the thermal radiation analysis model, such as... Figure 6 As shown, the following boundary conditions are defined: (a) constrain the degrees of freedom in directions 1-6 of the fixed points of the brake disc and dust baffle; (b) define the Gap Radiation property of the thermal radiation surface of the brake disc and dust baffle. In the analysis, the shape factor of the Gap Radiation property is defined as a function of the gap between the two surfaces. When the gap is zero, the shape factor is 1, and it decreases at a small rate as the gap increases.

[0036] In step S103, thermal radiation analysis is performed on the thermal deformation to calculate the temperature field.

[0037] In some embodiments, thermal radiation analysis is performed on the thermal deformation to calculate the temperature field results, including: The thermal deformation is divided into DS3 or DS4 solid meshes, and its solid mesh property is set to DC3D10. Thermal radiation analysis is performed on the DS3 or DS4 solid mesh using the first preset analysis step size, preset total time, and preset iteration step to calculate the temperature field.

[0038] In actual implementation, such as Figure 7 As shown, the ABAQUS thermal radiation analysis surface mesh attributes for thermal deformation are defined as DS3 or DS4, and the solid mesh attributes are DC3D10. Furthermore, the analysis type adopts a fixed analysis step size t=0.5s, an end time of total time T=200s, and an iteration step INC=1000 steps to perform thermal radiation analysis in order to calculate the temperature field.

[0039] In step S104, thermal deformation analysis is performed on the temperature field to calculate the gap value between the dust shield and the target brake disc surface, and thermal deformation is evaluated based on the gap value.

[0040] In some embodiments, thermal deformation analysis of the temperature field is performed to determine the gap value between the dust-collecting disc and the target brake disc surface, including: The temperature field is divided into S3 or S4 solid meshes, and its solid mesh attribute is set to C3D10M element. A second preset analysis step size and a second preset total time are used to perform thermal deformation analysis on the S3 or S4 solid mesh to calculate the gap value between the dust baffle and the target brake disc surface.

[0041] In actual implementation, such as Figure 8 and 9As shown, the surface mesh attribute of the temperature field is set to S3 or S4, and the solid mesh attribute is C3D10M. The temperature field is imported as a load *TEMPERATURE,FILE=temp.odb into the ABAQUS implicit solver. A fixed analysis step size of 0.1 is used, and the analysis ends with a total time of 1 to perform thermal deformation analysis in order to calculate the gap value between the dust baffle and the target brake disc surface, and to evaluate the thermal deformation based on the gap value.

[0042] In summary, the simulation analysis method for the influence of brake disc thermal radiation on dust disc thermal deformation proposed in this embodiment of the invention ensures both simulation accuracy and analysis efficiency. During the development stage, it can quickly verify whether the thermal deformation of the dust disc meets the design requirements. During the experimental verification stage, it can gradually replace the dust disc thermal deformation bench test, significantly shortening the R&D cycle and saving R&D costs.
