Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
In a first aspect, as shown in fig. 1, an embodiment of the present application provides a method for determining a setting position of a relief valve, which is used for a supercharged engine. The method for determining the setting position of the pressure relief valve comprises the following steps:
step S101, obtaining at least two setting positions of a pressure relief valve in a supercharged engine;
step S102, respectively establishing simulation models according to each setting position of the pressure relief valve in the supercharged engine;
and step S103, acquiring a simulation result of each simulation model, and determining the setting position of the pressure release valve in the supercharged engine according to the simulation result.
As can be appreciated, a supercharged engine is capable of driving ambient air into the cylinders. The supercharged engine can be a turbocharged engine or a mechanically supercharged engine. Specifically, taking a turbocharged engine as an example, when the vehicle is running normally, the exhaust gas generated after combustion in the cylinder drives the turbine to rotate, so that the external air can enter the cylinder through the intake pipe under the driving of the turbine. The pressure relief valve is connected with the air inlet pipeline, and gas in the air inlet pipeline can be discharged through the pressure relief valve, so that the pressure relief of the air inlet pipeline is realized. When the vehicle decelerates or parks, the air inlet pipeline is decompressed through the decompression valve, so that the phenomenon that the air inlet pipeline is exploded due to overhigh air content in the air inlet pipeline can be avoided.
In some examples, the pressure relief valve may be provided on the intake air line, or at other locations within the supercharged engine. It can be understood that the setting position of the pressure release valve affects the NVH (Noise, Vibration and Harshness) parameters of the vehicle, and the setting position of the pressure release valve is different, so is the NVH (Noise, Vibration and Harshness) parameters of the vehicle.
Specifically, the method for determining the setting position of the pressure relief valve includes obtaining at least two setting positions of the pressure relief valve in the supercharged engine, and in some examples, the at least two setting positions of the pressure relief valve in the supercharged engine may be determined empirically, or may also be determined according to a spatial structure inside the supercharged engine.
And respectively establishing a simulation model according to each set position of the pressure relief valve in the supercharged engine. It will be appreciated that the simulation model is a finite element simulation model. In some examples, different simulation software may be used to build the simulation model according to different use requirements.
And acquiring a simulation result of each simulation model, and determining the setting position of the pressure relief valve in the supercharged engine according to the simulation result. Understandably, the NVH parameter of the vehicle can be determined through the simulation result, so that the setting position of the pressure release valve in the supercharged engine is determined according to the simulation result, and the problem that the NVH parameter of the vehicle is too large and the use performance of the vehicle is influenced due to the fact that the setting position of the pressure release valve is not appropriate can be avoided. Meanwhile, the situation that the pressure release valve is not suitable for the arrangement position of the pressure release valve, resonance is generated between the pressure release valve and the engine, the pressure release valve supporting device is broken, and the like is avoided, and the use reliability of the vehicle is further improved.
In some examples, the simulation results of all the simulation models may be combined into a simulation result set, and the setting position of the pressure relief valve in the supercharged engine is determined according to the simulation result set.
In some examples, one setting position of the pressure relief valve in the supercharged engine can be determined according to the simulation result, and a plurality of setting positions of the pressure relief valve in the supercharged engine can also be determined according to the simulation result, so that the flexibility of the method for determining the setting position of the pressure relief valve is improved.
According to the embodiment of the application, the setting position of the pressure release valve in the supercharged engine can be determined according to the simulation result of the simulation model, the situation that the NVH parameter of the vehicle is increased due to the fact that the setting position of the pressure release valve is not appropriate is avoided, and the using performance of the vehicle is improved. Meanwhile, the situation that the arrangement position of the pressure release valve is not appropriate, the pressure release valve and the supercharged engine resonate to cause the supporting device of the pressure release valve to break due to resonance can be avoided, and the running reliability of the vehicle is ensured. In addition, the arrangement position of the pressure release valve in the supercharged engine is determined in a simulation mode, the design period of the vehicle can be shortened, the design efficiency of the vehicle is improved, and the design cost of the vehicle is reduced.
In some examples, the simulation results include frequency values of the first order modes of the pressure relief valve.
It can be understood that the frequency value of the first-order mode of the pressure relief valve is the excitation frequency value of the external force of the pressure relief valve under the mode shape of the first-order mode. When the difference between the frequency value of the first-order mode of the pressure relief valve and the frequency value of the first-order mode of the supercharged engine is larger, the NVH parameter value of the vehicle is smaller. Conversely, the smaller the difference between the frequency value of the first-order mode of the relief valve and the frequency value of the first-order mode of the supercharged engine, the larger the NVH parameter value of the vehicle. When the frequency value of the first-order mode of the pressure release valve is equal to the frequency value of the first-order mode of the supercharged engine, the pressure release valve can resonate with the supercharged engine, and the supporting device and the like are prone to breakage.
Therefore, the set simulation result comprises a frequency value of the first-order mode of the pressure release valve, and the magnitude of the NVH parameter value of the vehicle can be obtained through the frequency value of the first-order mode of the pressure release valve, so that the NVH parameter value of the vehicle can be prevented from being increased due to the fact that the set position of the pressure release valve is not appropriate, resonance of the pressure release valve and the supercharged engine can be avoided, and the running reliability of the vehicle is further improved. And the setting position of the pressure relief valve is determined through the frequency value of the first-order mode of the pressure relief valve, the logic is simple, and the determining efficiency of the setting position of the pressure relief valve is improved.
In some examples, the setting position of the first-order frequency value of the pressure relief valve, which is greater than the set frequency threshold value, can be used as the setting position of the pressure relief valve in the supercharged engine, so that different set frequency threshold values can be set according to different use requirements, and the flexibility of the determination method of the setting position of the pressure relief valve is improved.
In some examples, as shown in fig. 2, the step of determining the setting position of the relief valve in the supercharged engine based on the simulation result includes:
step S201, obtaining a frequency value of a first-order mode of a pressure relief valve corresponding to each simulation model;
step S202, taking the maximum value in the frequency values of the first-order modes of the pressure relief valves as a target frequency value;
in step S203, the set position of the relief valve corresponding to the target frequency value is set as the set position of the relief valve in the supercharged engine.
It will be appreciated that the frequency of the first order mode of the engine increases with increasing engine speed. Therefore, the maximum value of the frequency values of the first-order modes of the pressure relief valves is used as the target frequency value, the setting position of the pressure relief valve corresponding to the target frequency value is used as the setting position of the pressure relief valve in the supercharged engine, the difference between the frequency value of the first-order modes of the pressure relief valves and the frequency value of the first-order modes of the supercharged engine can be further increased, the NVH parameter of the vehicle is reduced, and the running reliability of the vehicle is ensured.
In some examples, the number of the maximum values among the frequency values of the plurality of pressure relief valve first-order modes may be plural.

and determining at least one of the structure, the material and the rigidity of the supporting device according to the setting position of the pressure relief valve in the supercharged engine.
It will be appreciated that the number of support means may be one or more. After the setting position of the pressure release valve is determined, at least one of the structure, the material and the rigidity of the supporting device is determined according to the setting position of the pressure release valve, so that the structure, the material or the rigidity of the supporting device can be matched with the setting position of the pressure release valve, NVH parameters of the vehicle are further reduced, the service performance of the vehicle is improved, meanwhile, the occurrence of the fracture condition of the supporting device can be reduced, and the running reliability of the vehicle is ensured.
In some examples, the supporting device may be made of metal, rubber, or the like, so as to meet different use requirements.
In some examples, as shown in fig. 3, the step of determining at least one of a structure, a material, and a rigidity of the support device based on a position of the relief valve in the supercharged engine includes:
step S301, determining performance parameters of the supercharged engine according to the setting position of the pressure release valve in the supercharged engine;
step S302, judging whether the performance parameter is larger than a performance parameter threshold value;
step S303, when the performance parameter is greater than the performance parameter threshold, adjusting at least one of a structure, a material, and a rigidity of the supporting device.
Wherein the performance parameter includes at least one of a noise parameter, a vibration parameter, and a roughness of acoustic vibration parameter.
In some examples, after determining the setting position of the pressure relief valve in the supercharged engine, the performance parameters of the supercharged engine can be obtained through an experimental mode and can also be obtained through a simulation mode.
And judging whether the performance parameter is larger than a performance parameter threshold value or not, wherein the performance parameter comprises at least one of a noise parameter, a vibration parameter and a sound vibration roughness parameter. When the performance parameter is larger than the performance parameter threshold, at least one of the structure, the material and the rigidity of the supporting device is adjusted, that is, at least one of the structure, the material and the rigidity of the supporting device is adjusted according to the relationship between the noise parameter, the vibration parameter, the sound vibration roughness parameter and the performance parameter threshold of the vehicle, so that the performance parameter of the vehicle can be smaller than the performance parameter threshold, and the service performance of the vehicle is further ensured.
It can be understood that after at least one of the structure, the material and the rigidity of the supporting device is adjusted, the performance parameters of the supercharged engine are obtained again until the performance parameters of the supercharged engine can be smaller than the performance parameter threshold value, and the reliability of the method for determining the setting position of the pressure release valve is improved.
