Description

Technical Field

[0001] This invention belongs to the field of modular design of coolant pipelines in commercial vehicles, specifically relating to a parametric design method and control method for nylon corrugated pipe bundles for coolant in commercial vehicles. Background Technology

[0002] By developing nylon corrugated pipes, the problem of reducing costs without compromising quality and improving assembly efficiency has been solved, achieving the greatest common denominator for cost reduction through technology, and shifting from the "debate between rubber and plastics" to the "sum of rubber and plastics". However, the application of new products has also brought new problems. Since nylon corrugated pipe bundles cannot be freely cut on the production site, they need to be laid out in one go with correct interlocking interfaces. The general finalization process is design - trial assembly - design revision - trial assembly again - design revision again and filing - finalization.

[0003] The original technical solution was designed based on the predetermined route of the pipeline without any compensation design for the pipeline. This resulted in insufficient adjustment margin during the actual assembly process, requiring frequent trial assembly and verification. The pipeline layout also needed to be adjusted frequently, which was not conducive to ensuring the stability of quality.

[0004] A new design method is needed to solve the problem of how to quickly convert rubber hoses of existing vehicle models into nylon corrugated tubing and to finalize the design of nylon corrugated tubing for newly developed vehicles, thereby improving design accuracy and shortening the finalization time. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a parametric design method for nylon corrugated tubing bundles for commercial vehicle coolant. By constructing a tubing bundle design model and applying a parametric design method, it can effectively solve the problems of how to quickly convert rubber hoses of existing vehicle models into nylon corrugated tubing bundles and finalize the design of nylon corrugated tubing bundles for newly developed vehicles. The optimized process is model building - parametric design - finalization, which improves the design accuracy and shortens the finalization time.

[0006] To address the aforementioned problems in the existing technology, the technical solution adopted by this invention is as follows:

[0007] A parametric design method for nylon corrugated tubing bundles for commercial vehicle coolant includes the following steps:

[0008] Step 1: Based on the vehicle model, select the positions of each key point in the pipeline relative to the vehicle coordinate system;

[0009] Step 2: Obtain the pipeline design model based on the pipeline design criteria and the selection of key points;

[0010] Step 3: Design the pipeline route and the locations of the laying fixing points and bending points, and output the coordinates of the laying fixing points and bending points, the connection specifications of the connection ports, and the specifications of the connecting pipelines;

[0011] Step 4: Calculate the distance between each pair of adjacent key points, assign different bending radii according to the location of the bending points, and preliminarily calculate the pipeline length;

[0012] Step 5: Adjust the pipeline to meet the array production mode, complete the compensation parameters, and accurately calculate the pipeline length;

[0013] Step 6: Adjust the bending points according to the calculated pipeline length to complete the finalized pipeline drawing.

[0014] This embodiment simplifies the process by constructing a tubing design model and employing a parametric design method, resulting in a process of model building, parametric design, and finalization. Optimizing the process and establishing a new design method transforms the tubing design from concrete forms to abstract numbers, creating a modular design model and parametric calculations for the tubing. This effectively solves the problems of how to quickly convert rubber hoses for existing vehicle models into nylon corrugated tubing and how to finalize the nylon corrugated tubing design for newly developed vehicles.

[0015] A parametric design method for nylon corrugated tubing bundles for commercial vehicle coolant includes the following steps:

[0016] Step 1: Based on the vehicle model, select the position of each key point in the pipeline (including input end, output end, and pipeline node) relative to the vehicle coordinate system;

[0017] The vehicle layout determines the position of each key point in the pipeline relative to the vehicle coordinate system. In order to reduce technical issues, the positions of each system involving coolant pipelines are relatively fixed after optimization. This further narrows the pipeline model's adaptability range, and then we proceed to the next step.

[0018] Step 2: Obtain the pipeline design model based on the pipeline design criteria and the selection of key points;

[0019] Based on the sub-height of the chassis and the position of the crossbeams of different platform models, combined with the pipeline design principles and the selection of fixing points, a pipeline design model was developed, which ensured the accuracy of the design model and improved its applicability.

[0020] Step 3: Design the pipeline route and the locations of the laying fixing points and bending points, and output the coordinates of the laying fixing points, the coordinates of the bending points, the connection specifications of the connection ports, and the specifications of the connecting pipelines;

[0021] The extracted parameters are designed based on the input and output ends, including the pipeline route and the locations of the laying fixed points and bends. The extracted parameters include the coordinates of the laying fixed points and bends, the connection specifications of the connection ports, and the specifications of the connecting pipelines. This ensures that all parameters are extracted in a single coordinate system, facilitating parameter calculation.

[0022] Step 4: Calculate the distance between each pair of adjacent key points, assign different bending radii according to the location of the bending points, and preliminarily calculate the pipeline length;

[0023] Based on the coordinates of the laying fixing points, bending points, connection specifications of the connection ports, and specifications of the connecting pipes, complete the parameter design, calculate the distance between each pair, assign different bending radii according to the location of the bending points, preliminarily calculate the pipe length, and then proceed to the next step;

[0024] The parameter design involves calculating the distance between each pair of points based on the bending point parameters, assigning different bending radii R according to the location of the bending points, and initially calculating the pipe length L. This ensures that the distance between two points calculated in a coordinate system is an absolute value, and the data is reliable and accurate. Selecting different R values ​​according to different assembly environments can ensure that the deviation between the design effect and the actual assembly is reduced. The initially calculated pipe length L can provide a basis for mold arrangement.

[0025] Step 5: Adjust the pipeline to meet the array production mode, complete the compensation parameters, and accurately calculate the pipeline length;

[0026] Based on the initial layout, adjust the pipeline to meet the array production mode, complete the compensation parameters, and accurately calculate the pipeline length before proceeding to the next step.

[0027] The compensation parameters are adjusted based on the initial mold layout to move and integrate the pipe bends, ensuring the pipes meet the array production mode and completing parameter compensation. This guarantees the array production of the pipes, improves the versatility of the pipes, and reduces technical issues.

[0028] Step 6: Adjust the bending points according to the calculated pipeline length to complete the finalized pipeline drawing.

[0029] The standardized piping is designed based on the precisely calculated piping after adjusting the bending points, ensuring the consistency of the actual effect after the piping is assembled.

[0030] Furthermore, the design model consists of input terminals, distances, compensation parameters, bend points, pipe nodes, output terminals, and pipe diameters. Pipe nodes, acting as binding points, are prioritized for positioning in vehicle layouts, maintaining their position across different vehicle models. Input and output terminals vary depending on the vehicle model and system. Distances, compensation parameters, bend points, and pipe diameters are adjusted based on the optimal pipe design route and the port requirements of the input and output terminals.

[0031] Furthermore, the preliminary piping diagram is drawn, and different bending radii R are assigned to the bending points. The preliminary pipe length L is calculated, ensuring that the distance between two points calculated in a coordinate system is an absolute value, and the data is reliable and accurate. Selecting different R values ​​according to different assembly environments can ensure that the deviation between the design effect and the actual assembly is reduced. The preliminary calculation of the pipe length L can provide a basis for mold arrangement. By compensating parameters, the movement and integration of pipe bending points are adjusted to make the pipes meet the array production mode, completing parameter compensation; ensuring the array production of pipes, improving the versatility of pipes, reducing technical conditions, and effectively solving the problem of how to quickly convert rubber hose pipes of existing vehicle models into nylon corrugated tubing and the nylon corrugated tubing of newly developed models, improving the design accuracy and shortening the finalization time.

[0032] The beneficial effects of this invention are:

[0033] 1. This invention simplifies the process by constructing a pipe bundle design model and using a parametric design method, resulting in a process of building a model, parametric design, and finalization. The optimized process and the establishment of a new design method transform the pipe design from a concrete form to an abstract number, forming a modular design model and parametric calculation for the pipe, thus avoiding the complex finalization process and pipe design method of the original technical solution.

[0034] 2. The compensation parameters are adjusted and integrated based on the initial mold layout to ensure the pipeline meets the array production mode and complete parameter compensation. This guarantees the array production of the pipeline, improves the versatility of the pipeline, reduces technical issues, and effectively solves the problem of how to quickly convert rubber hoses of existing models into nylon corrugated tubing and finalize nylon corrugated tubing for newly developed models. This improves design accuracy and shortens the finalization time. Attached Figure Description

[0053] like Figure 1-3 As shown, a parametric design method for nylon corrugated pipe bundles for commercial vehicle coolant includes the following steps:

[0054] Step 1: Based on the vehicle model, select the position of each key point in the pipeline (including input end, output end, and pipeline node) relative to the vehicle coordinate system;

[0055] The vehicle layout determines the position of each key point in the pipeline relative to the vehicle coordinate system. In order to reduce technical issues, the positions of each system involving coolant pipelines are relatively fixed after optimization. This further narrows the pipeline model's adaptability range, and then we proceed to the next step.

[0056] Step 2: Obtain the pipeline design model based on the pipeline design criteria and the selection of key points;

[0057] Based on the sub-height of the chassis and the position of the crossbeams of different platform models, combined with the pipeline design principles and the selection of fixing points, a pipeline design model was developed, which ensured the accuracy of the design model and improved its applicability.

[0060] Step 4: Calculate the distance between each pair of adjacent key points, assign different bending radii according to the location of the bending points, and preliminarily calculate the pipeline length;

[0061] Based on the coordinates of the laying fixing points, bending points, connection specifications of the connection ports, and specifications of the connecting pipes, complete the parameter design, calculate the distance between each pair, assign different bending radii according to the location of the bending points, preliminarily calculate the pipe length, and then proceed to the next step;

[0062] The parameter design involves calculating the distance between each pair of points based on the bending point parameters, assigning different bending radii R according to the location of the bending points, and initially calculating the pipe length L. This ensures that the distance between two points calculated in a coordinate system is an absolute value, and the data is reliable and accurate. Selecting different R values ​​according to different assembly environments can ensure that the deviation between the design effect and the actual assembly is reduced. The initially calculated pipe length L can provide a basis for mold arrangement.

[0063] Step 5: Adjust the pipeline to meet the array production mode, complete the compensation parameters, and accurately calculate the pipeline length;

[0064] Based on the initial layout, adjust the pipeline to meet the array production mode, complete the compensation parameters, and accurately calculate the pipeline length before proceeding to the next step.

[0065] The compensation parameters are adjusted based on the initial mold layout to move and integrate the pipe bends, ensuring the pipes meet the array production mode and completing parameter compensation. This guarantees the array production of the pipes, improves the versatility of the pipes, and reduces technical issues.

[0066] Step 6: Adjust the bending points according to the calculated pipeline length to complete the finalized pipeline drawing.

[0067] The standardized piping is designed based on the precisely calculated piping after adjusting the bending points, ensuring the consistency of the actual effect after the piping is assembled.

[0068] Example 3:

[0069] Based on Example 2, the design model consists of input end, distance, compensation parameters, bend point, pipeline node, output end, and pipe diameter.

[0070] Pipeline nodes, as binding points, should be prioritized in vehicle layout. The positioning should remain unchanged for different vehicle models. The input and output ends should be varied according to different vehicle models and systems. The distance, compensation parameters, bend points, and pipe diameter should be varied according to the optimal pipeline design route and the requirements of the input and output ports.

[0071] Example 4:

[0072] like Figure 2 and 3 The diagram shown illustrates a pipeline design model for a parametric design method of nylon corrugated tubing for commercial vehicle coolant, specifically demonstrating how to calculate and correct parameters, including the following steps:

[0073] Step 1: Based on the vehicle model layout, solidify the positions of the input terminals, pipeline nodes, and output terminals;

Figure 3 The example of the finalized drawing of the parametric design method for nylon corrugated pipe bundles for commercial vehicle coolant described in this invention allows for the creation of a solidified drawing. Only the bending points need to be marked, and the length of the corrugated ends does not need to be specified.

[0080] Example 5:

[0081] Based on Example 4, the coordinate information is extracted and the distance is calculated in the vehicle coordinate system according to the determined input end, pipeline node, output end and bending point. This ensures that all parameters are extracted in one coordinate system, which facilitates parameter calculation.

Selecting different R values ​​according to different assembly environments can ensure that the deviation between the design effect and the actual assembly is reduced. The preliminary calculation of the pipe length L can provide a basis for mold arrangement.

[0083] By compensating parameters and adjusting the movement and integration of pipeline bending points, the pipeline can meet the array-type production mode and complete parameter compensation. This ensures the array-type production of the pipeline, improves the versatility of the pipeline, reduces technical conditions, and effectively solves the problem of how to quickly convert rubber hose pipelines of existing vehicle models into nylon corrugated tubing and the finalization of nylon corrugated tubing for newly developed models. This improves the design accuracy and shortens the finalization time.
