[0003] The automotive powertrain provides power for the entire vehicle, requiring numerous pipelines to deliver fluids such as lubricants and coolants to the moving machinery. Metal piping offers high structural strength and reliability, but places high demands on installation location and shape. Complex shapes or large relative position deviations create the risk of installation becoming difficult or impossible. To address the installation challenges associated with complex rigid piping, flexible braided tubing has become the optimal solution. Flexible tubing is used in the mechanical, electrical, and construction industries, offering excellent flexibility and the ability to adjust the location, shape, and potential deformation of the piping. This effectively reduces installation time, minimizes system failure rates, and saves installation costs.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0062] See also Figure 1 , shown is the frequency analysis method provided by the first embodiment of the present invention. The frequency analysis method provided by this embodiment can objectively and accurately complete the frequency analysis of the flexible connecting pipe, so that the corresponding frequency characteristics can be accurately obtained, which correspondingly improves work efficiency.

[0063] Specifically, this embodiment provides:

[0064] A frequency analysis method specifically comprises the following steps:

[0065] Step S10, when the flexible connecting tube is acquired in real time, one end of the flexible connecting tube is fixed in a preset analysis platform, and a corresponding preset pressure is applied to the other end of the flexible connecting tube;

[0066] Step S20, recording in real time the target displacement of the flexible connecting pipe under the preset pressure, acquiring in real time the installation structure corresponding to the flexible connecting pipe, and constructing a first finite element model corresponding to the flexible connecting pipe and a second finite element model corresponding to the installation structure;

[0067] In step S30, a displacement analysis is performed on the flexible connecting pipe to obtain corresponding target position information, and based on the position information, the first finite element model is assembled to the second finite element model to generate a corresponding target finite element model, and the modal frequency of the target finite element model under the actual installation boundary is calculated in real time to complete the corresponding frequency analysis.

[0068] Specifically, in this embodiment, the following steps are implemented:

[0069] Step 1: Flexible pipe disturbance test: fix one end of the flexible connection unit, apply a vertical downward force on the other end, and record the end displacement.

[0070] 1.1 Fix one end of the flexible connection unit and record the specific position of the other end.

[0071] 1.2 Hang an object of a certain mass vertically at the other end or use a force meter to apply a vertical downward force. The hanging object can be a weight of a certain mass or other object.

[0072] 1.3 Record the position of the other end when a weight is hung or a downward vertical force is applied, and calculate the displacement of the other end.

[0073] Step 2: Establish a model, and establish finite element models of the flexible connection unit and the installation structure respectively.

[0074] 2.1 Collect the geometric models of the various structures and installation structures of the flexible pipeline, as well as the material type, physical parameters, weight data, constraint relationships, etc. of each part.

[0075] 2.2 Build a mesh model for the flexible pipe. The flexible pipe can be made into solid elements or shell elements. It is recommended to use a hexahedral mesh for the solid elements. Establish the connection relationship between the parts according to the actual assembly. Assign the corresponding material parameters to the metal structure according to the actual type. Assign empirical parameters to the flexible segment first.

[0076] 2.3 Establish a mesh model of the supporting shell structure. The supporting shell structure can be made into a tetrahedral mesh. The shell parts are connected according to the actual assembly and the corresponding material parameters are assigned according to the actual material type.

[0077] The above modeling steps are performed in the pre-processing software Hypermesh. It is necessary to ensure that the model quality is consistent with the actual quality. The process of the body is as follows:

[0078] Import the geometric model into the pre-processing software;

[0079] Create mesh elements based on the geometric structure. Depending on the part type and shape modeling requirements, they can be shell elements or solid elements.

[0080] Define the material properties of the mesh elements to ensure that the model quality is consistent with the actual quality;

[0081] The connection relationship between each part is established according to the actual assembly.

[0082] Flexible connection unit structure

[0083] Step 3, calibrate preset parameters: perform displacement analysis on the flexible connection unit according to the test conditions, keep the boundary conditions and loads consistent with the above-mentioned flexible pipe disturbance test, and debug the material parameters of the flexible section of the flexible pipe until the analyzed displacement result of the flexible pipe end is consistent with the measured displacement result.

[0084] 3.1 According to the test boundary conditions, the flexible tube is fully constrained in the model, and the same load as the test is applied to the other end to analyze the displacement change value of the end.

[0085] 3.2 Debug the preset material parameters of the flexible section until the analyzed displacement results at the end of the flexible tube are consistent with the measured displacement results.

[0086] (1) Analyze and obtain the displacement results of the flexible pipe end and compare them with the test results;

[0087] (2) If they are consistent, proceed to step 4; if not, adjust the preset material parameters of the flexible section until the analytical displacement result of the flexible tube end is consistent with the measured displacement result, and then proceed to step 4.

[0088] 3.3 Obtain an equivalent material parameter combination that can reflect the true stiffness of the flexible segment. The modal frequency result is affected by the density and elastic modulus parameters of the parts. Since the physical density of a certain mass is determined when the structure is determined, the present invention adjusts the elastic modulus of the material so that the flexible segment has the structural stiffness under the real state. The predicted parameter is the elastic modulus.

[0089] Step 4: Model assembly: assembling the finite element model of the flexible connection unit onto the finite element model of the mounting structure according to the flexible pipe position information.

[0090] Step 5: Natural frequency analysis: Calculate the modal frequency of the flexible connection unit under the actual installation boundary to meet the design frequency requirements.

[0091] 5.1 Perform modal analysis based on the model established in step 4 to obtain the natural frequency of the flexible connection unit;

[0092] 5.2 Compare the calculated natural frequency freq1 with the design frequency target freq2 to evaluate whether the flexible pipe meets the design requirements;

[0093] 5.3 If the design requirements are met, the component design is frozen; if not, the structural design is optimized until the natural frequency of the flexible connection unit meets the design frequency requirements.

[0094] freq1 is the installation natural frequency of the flexible connection element obtained by analysis.

[0095] freq2 is the design frequency target,

[0096] If the flexible connection unit is installed on the powertrain, In this case, if freq1>freq2, the flexible connection unit is considered to meet the frequency design requirements. max is the maximum engine speed.

[0097] If the flexible connection unit is installed on other non-powertrain structures such as the chassis or body, freq2 can be a single value or a frequency range, which needs to be treated differently according to the specific situation.
