[0052] Example 1
[0053] An embodiment of the present application provides a method for calculating a graphics of a passenger car's steering performance.
[0054] See also Figure 1 The bus steering performance graph calculation method includes steps S101-105:
[0055] S101: Obtaining adjustable driving parameters and locked state driving parameters of a target bus model, and building a bus framework graphic according to the adjustable driving parameters and the locked state driving parameters.
[0056] In this embodiment, buses, as a widely used means of transportation, can be subdivided into multiple types according to their purpose, size, passenger capacity, design features, etc. A target bus model whose turning performance needs to be calculated is selected, and the adjustable driving parameters and locked state driving parameters of the bus model are obtained.
[0057] For example, adjustable drive parameters refer to parameters that can be flexibly adjusted according to needs during the design and simulation process. In the bus model, the adjustable drive parameters mainly include the turning angle of the outer wheel and the length of the bus. The locked state drive parameters are constant parameters determined according to the actual designed vehicle model, including the wheelbase, front and rear overhangs, kingpin center distance and vehicle width of the bus. The locked state drive parameters have been determined in the vehicle model design stage and usually do not change during the simulation and optimization process.
[0058] Optionally, after obtaining the above parameters, the two-dimensional sketch module in the CREO three-dimensional software is used to build the bus frame graphics. This module is endowed with functions such as line constraints, dimension drive, and graphic attribute settings, and can accurately construct the relevant dimensions and shapes of the bus steering system. In the sketch, the length outline, width outline, front overhang, wheelbase, kingpin center distance and other related points and lines of the bus are drawn and associated in the form of lines to build the bus frame graphics of the bus steering system. By adjusting the adjustable drive parameters, the CREO software simulates the bus model under the locked state drive parameters, and simulates the steering performance under different turning radii and bus lengths through the built bus frame graphics and the set constraint rule graphics, and evaluates whether the bus's maneuverability meets the design requirements.
[0059] S102: Constructing a constraint rule graph according to the bus framework graph.
[0060] In this embodiment, by setting the constraint rule graphics in the bus frame graphics, it can be ensured that the various elements in the bus frame graphics (such as the inner wheel turning angle line, outer wheel turning angle line, turning center, side wall and channel of the bus) maintain the correct relative position and relationship during the simulation process.
[0061] In one embodiment, S102 includes: setting a turning center outside the bus frame figure; constraining the inner wheel turning angle line, the outer wheel turning angle line and the turning center of the bus to obtain a first constraint rule figure.
[0062] In this embodiment, the inner wheel turning angle line of the bus is the path passed by the wheel close to the inside of the turn (usually the inner front wheel) during the turning process; the outer wheel turning angle line of the bus is the path passed by the wheel away from the inside of the turn (usually the outer front wheel) during the turning process. Since the turning radius of the outer wheel is larger when the bus turns, the outer wheel turning angle line will be farther away from the center of the turn than the inner wheel turning angle line.
[0063] For example, when the bus is turning, the axes of all wheels will intersect at one point (i.e., the turning center) to ensure that the bus can turn smoothly and stably. Therefore, it is necessary to set the first constraint rule graph, i.e., the inner wheel turning angle line and the outer wheel turning angle line always pass through the turning center of the bus regardless of how the position and angle are adjusted. Figure 2 ,By setting constraint rule graphics in the bus frame graphics, the inner wheel turning angle line, the outer wheel turning angle line and the turning center of the bus are constrained, ensuring the accuracy and reliability of the bus turning performance during the simulation, thus reflecting the real turning performance of the bus under different conditions.
[0064] See also Figure 3 In one embodiment, the S102 further includes steps S1021-S1024:
[0065] S1021: Determine the intersection of the rear axle of the target bus model and the inner side of the bus, determine the radius of the inner channel circle according to the distance between the intersection and the turning center, and obtain the inner channel circle according to the turning center and the inner channel circle radius.
[0066] In this embodiment, continue to see Figure 2 , is a constraint rule graphic display diagram. The rear axle of the bus is an important component connecting the rear wheel and the body. It is located at the rear of the bus and connected to the bottom of the body. The inner side of the bus is the part of the body close to the inner side of the turn. In the bus outline in the bus frame graphic, confirm the intersection of the position of the rear axle of the bus and the inner side of the bus. This intersection is the point where the inner wheel turning angle line is closest to the turning center during the turning process. The distance between the intersection and the turning center is the radius of the inner channel circle. The inner channel circle is drawn according to the turning center and the radius of the inner channel circle. The inner channel circle intuitively shows the minimum space range required by the bus during the turning process.
[0067] S1022: Determine the farthest point on the outer side of the front enclosure of the target bus model, determine the radius of the outer channel circle according to the distance between the farthest point on the outer side of the front enclosure and the turning center, and obtain the outer channel circle according to the turning center and the radius of the outer channel circle.
[0068] In this embodiment, the farthest point on the outside of the bus front wall (front part of the bus body) is found in the body contour. The farthest point will be used to determine the radius of the outer channel circle, which is the point of the outer wheel turning angle line farthest from the turning center during the turning process. The radius of the outer channel circle is determined according to the turning center and the farthest point on the outside of the front wall, and the outer channel circle is drawn according to the turning center and the radius of the outer channel circle. The outer channel circle intuitively shows the maximum space range required by the bus during the turning process, which helps designers evaluate the turning performance of the bus.
[0069] S1023: constraining the inner channel circle and the intersection point to obtain a second constraint rule graph.
[0070] In this embodiment, in order to ensure that the inner channel circle and the intersection maintain the correct relative position during the simulation, a second constraint rule graphic is set in the bus frame graphic to constrain the inner channel circle and the intersection. The second constraint rule graphic ensures that the inner channel circle always passes through the intersection during the simulation, thereby reflecting the actual relationship between the rear axle and the inner side wall when the bus turns.
[0071] S1024: Constrain the outer channel circle and the farthest point on the outer side of the front wall of the bus to obtain a third constraint rule graph.
[0072] In this embodiment, in order to ensure that the outer channel circle and the farthest point on the outside of the front enclosure maintain a correct relative position during the simulation, a third constraint rule graphic is set in the bus frame graphic to constrain the outer channel circle and the farthest point on the outside of the front enclosure. The third constraint rule graphic ensures that the outer channel circle always passes through the farthest point on the outside of the front enclosure during the simulation, reflecting the actual position of the outside of the front enclosure when the bus turns.
[0073] S103: respectively setting the attributes and digital colors corresponding to the adjustable driving parameter and the locked state driving parameter.
[0074] In this embodiment, it is first necessary to set the properties of the parameters and the digital colors of the parameters in the CREO modeling software, wherein the adjustable driving parameters can be changed according to user needs, such as the turning angle of the outer wheel, the length of the bus, etc., and the change of the adjustable driving parameters will directly affect the shape and size of the graphics; the locked state driving parameters are data determined according to the actual vehicle model design, and are usually not allowed to be changed, such as the wheelbase, front and rear overhangs, kingpin center distance, vehicle width, etc. of the bus; the parameters (i.e., result data) generated by the change of the driving graphics driven by the adjustable driving parameters are automatically calculated according to the changes in the adjustable driving parameters and the locked state driving parameters, and are used to evaluate the rationality of the bus design.
[0075] In one embodiment, S103 includes: setting the attribute of the adjustable driving parameter to a variable attribute and the digital color to a first color; setting the attribute of the locked state driving parameter to a quantitative attribute and the digital color to a second color.
[0076] In this embodiment, continue to see Figure 2 , the properties of adjustable driving parameters are set as variable properties, indicating that the values of these parameters can be changed, and the digital color is set to the first color such as white to distinguish and highlight these parameters. The properties of locked state driving parameters are set as quantitative properties, indicating that the values of these parameters are fixed, and the digital color is set to the second color such as brown to indicate that these parameters cannot be changed. The parameters (i.e., result data) generated by the change of the driving graph driven by the adjustable driving parameters are displayed in white brackets.
[0077] S104: Selecting a target adjustable driving parameter according to the preset turning performance of the target bus model, determining a position of the target adjustable driving parameter according to the attribute and digital color of the target adjustable driving parameter, and adjusting the target adjustable driving parameter according to the numerical value of the target adjustable driving parameter.
[0078] In this embodiment, the preset turning performance includes evaluation indicators such as the minimum turning radius and turning stability, wherein the minimum turning radius refers to the radius of the circle that the center point of the bus passes through when the bus can turn with the minimum path. A smaller turning radius means that the bus can complete the turn in a narrower space; turning stability refers to the ability of the bus to maintain a stable driving without side slipping or excessive tilting during the turning process. The target adjustable driving parameter is selected according to the preset turning performance that needs to be achieved. If the turning radius and turning stability of the bus need to be adjusted, the outer wheel angle of the adjustable driving parameter is selected as the target adjustable driving parameter. And according to the digital color and attribute of the selected adjustable driving parameter in the bus frame graphic, the position of the target adjustable driving parameter is determined, and the target adjustable driving parameter is adjusted according to the numerical value of the target adjustable driving parameter.
[0079] In one embodiment, S104 includes: calculating the adjustment interval and adjustment amplitude of the target adjustable driving parameter, and setting multiple adjustment values of the driving parameter to be adjusted according to the target adjustable driving parameter; and inputting the multiple adjustment values into the position of the target adjustable driving parameter in batches.
[0080] In this embodiment, if the target adjustable driving parameter is the outer wheel angle, the adjustment range of the outer wheel angle and the amplitude of each adjustment are determined according to the current outer wheel angle setting of the bus, the preset turning performance requirements, and the historical adjustment experience. And the bus dynamics model is determined. According to the calculated adjustment range and amplitude, a series of adjustment values that need to be tested are set, and these adjustment values are input in batches into the positions corresponding to the target adjustable driving parameter, and the outer wheel angle is gradually tested and adjusted to achieve the required turning performance.
[0081] S105: updating the constraint rule graph according to the adjusted target adjustable driving parameters to obtain a new constraint rule graph and visualization result data.
[0082] In this embodiment, the lines of the driving constraint rule graphs (such as the first constraint rule graph, the second constraint rule graph, and the third constraint rule graph) are adjusted according to the adjusted target adjustable driving parameters (such as the outer wheel turning angle and the length of the bus) to generate the adjusted constraint rule graphs and related visualization result data. Figure 2 , which is the data display chart before adjustment, see Figure 4 , which is a graph showing the result data calculated based on the adjusted values.
[0083] See also Figure 5 In one embodiment, the S105 includes S1051-S1052:
[0084] S1051: driving the position, length and angle of the lines of the constraint rule graph to be adjusted according to the adjustment value to obtain a new constraint rule graph.
[0085] In this embodiment, the multiple adjustment values obtained in step S104 are input into the positions of the target adjustable driving parameters in batches, the positions, lengths, angles and other attributes of the corresponding lines in the constraint rule graph are adjusted, and it is verified whether the adjusted constraint rule graph conforms to the preset constraint rules. An updated new constraint rule graph is obtained, which intuitively shows the influence of the adjusted driving parameters on the geometric relationship between the bus parameters.
[0086] S1052: Calculate result data according to the adjustment value and the locking state driving parameter, and visualize the result data to obtain visualized result data.
[0087] In this embodiment, based on the adjustment values and the locked state driving parameters, the calculation module of the CREO modeling software is combined with the bus dynamics model or other relevant algorithms to calculate the changed result data, which includes the distance between the inner channel circle and the outer channel circle, the force condition of the steering mechanism, the power requirement of the steering motor, and the stiffness and damping characteristics of the suspension.
[0088] Optionally, after the calculation results are visualized in digital form to obtain the visualized result data, they are embedded in the graphics of the bus frame graphics and the constraint rule graphics, and brackets and colors are set to display them in the bus frame graphics, so as to intuitively show the adjusted effect.
[0089] In one embodiment, after obtaining the new constraint rule graph and visualization result data, the method further includes: determining whether the visualization result data meets the expected result, and if so, determining that the adjustment of the target adjustable driving parameter is completed; if not, resetting the constraint rule graph or reselecting the adjustable driving parameter and adjusting it until the visualization result data meets the expected result.
[0090] In this embodiment, after obtaining the visualization result data, the visualization result data is compared with the preset expected result, and the expected result is determined based on the design goal, performance requirements, safety standards and other factors of the bus turning. If the visualization graph and the visualization result data meet the expected result, the process of determining the adjustable drive parameter of the adjustment target is completed. If the expected result is not met, it is necessary to reset the constraint rule graph or reselect the adjustable drive parameter. Repeat the above steps, and when the visualization result data finally meets the expected result, it is confirmed that the adjustment is completed, and the final parameter setting and result data may be used in the subsequent bus design, manufacturing or testing stage.
[0091] For example, the design team presets the expected turning performance results, such as the minimum turning radius not exceeding 12 meters and the lateral acceleration during turning must be kept within a certain range to ensure passenger comfort and the sideslip angle must be below the safety threshold. By adjusting the outer wheel angle, the calculated visualization data is compared with the preset expected results for a comprehensive evaluation.
[0092] The bus steering performance graphics calculation method provided in this embodiment obtains the adjustable driving parameters and the locked state driving parameters of the bus target model, builds the bus frame graphics according to the adjustable driving parameters and the locked state driving parameters; builds the constraint rule graphics according to the bus frame graphics; respectively sets the attributes and digital colors corresponding to the adjustable driving parameters and the locked state driving parameters; selects the target adjustable driving parameters according to the preset turning performance of the bus target model, determines the position of the target adjustable driving parameters according to the attributes and digital colors of the target adjustable driving parameters, and adjusts the target adjustable driving parameters according to the numerical values of the target adjustable driving parameters; updates the constraint rule graphics according to the adjusted target adjustable driving parameters, and obtains new constraint rule graphics and visualization result data. By constructing the constraint rule graphics based on the bus frame graphics, adjusting the adjustable driving parameters to update the constraint rule graphics, and obtaining a new constraint rule graphics and visualization result data, the adjustment results can be quickly visualized, which greatly improves work efficiency.
