[0037] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0041] The hydraulic circuit oil pressure setting method in the embodiments of this application, such as Figure 1 As shown, it includes the following steps:

[0042] Step S101: Determine at least one target oil-air content based on the hydraulic circuit requirement data.

[0043] Step S102: Determine the oil pressure-oil circuit resonance frequency relationship curve corresponding to the air content of each target engine oil.

[0044] Step S103: Obtain the operating frequency of the solenoid valve, and determine the oil pressure avoidance range based on the relationship curve between the operating frequency of the solenoid valve and the resonant frequency of each oil pressure-oil circuit.

[0045] Step S104: Determine the target oil pressure range based on the oil pressure avoidance range.

[0046] Specifically, the resonant frequency of a hydraulic circuit is related to the oil air content and oil pressure. Different hydraulic circuits have different oil air content due to variations in their circuit layout. This application first determines at least one target oil air content that meets the requirements of the target hydraulic circuit based on the required hydraulic circuit data. For each target oil air content, a corresponding oil pressure-oil circuit resonant frequency relationship curve is determined. Then, the operating frequency of the solenoid valve in the target hydraulic circuit is obtained. Since resonance noise will occur when the solenoid valve operating frequency is the same as the oil circuit resonant frequency, combining the solenoid valve operating frequency with each oil pressure-oil circuit resonant frequency relationship curve can determine the oil pressure range where frequency resonance may occur. This oil pressure range is used as the oil pressure avoidance range. By avoiding the oil pressure avoidance range when setting the oil circuit oil pressure, the problem of resonance noise in the hydraulic circuit can be solved.

[0047] In this embodiment, the target oil air content is first determined, then the corresponding oil pressure-oil circuit resonance frequency relationship curve is determined, and the oil pressure avoidance range is determined in combination with the solenoid valve operating frequency, so as to avoid resonance noise caused by the oil circuit resonance frequency being the same as the solenoid valve operating frequency.

[0048] In one embodiment, the hydraulic circuit requirement data includes an oil temperature range, and determining at least one target oil air content based on the hydraulic circuit requirement data specifically includes:

[0049] Substitute the oil temperature range into the oil temperature-air content curve, and select the air content corresponding to the oil temperature range as the oil air content range.

[0050] Determine at least one target oil-air content within the range of oil-air content.

[0051] Figure 2 An example of an oil temperature-air content curve is shown, where the oil air content gradually increases with increasing oil temperature, and the rate of increase gradually decreases. Different hydraulic circuits use different oil temperatures. This application embodiment determines the corresponding oil air content range by obtaining the oil temperature range used in the target hydraulic circuit and substituting this range into the oil temperature-air content curve.

[0052] The target oil air content can be any value within the oil air content range. Preferably, the upper and lower limits of the air content range can be selected as the two target oil air contents to obtain the most accurate oil pressure clearance range; for example... Figure 2 The oil air content range corresponding to the oil temperature range T1-T2 is R. L -R H Then determine R L and R HTo determine the target oil air content, two corresponding oil pressure-oil circuit resonant frequency relationship curves are established, as follows: Figure 3 As shown.

[0053] In one embodiment, determining the oil pressure-oil circuit resonance frequency relationship curve corresponding to each target oil air content specifically includes:

[0054] Based on the foaming characteristics of engine oil and the layout characteristics of the target oil circuit, the oil pressure-oil circuit resonance frequency relationship curve corresponding to the air content of each target engine oil was determined.

[0055] In this embodiment, based on the target hydraulic circuit layout characteristics and combined with the oil foaming characteristics, the oil pressure-oil circuit resonance frequency relationship curve corresponding to each target oil air content is measured. The oil air content in the target hydraulic circuit can be controlled to the target oil air content by combining the oil foaming characteristics. The oil circuit resonance frequency corresponding to different oil pressures is then calculated. By measuring the oil circuit resonance frequency data under multiple oil pressures, the oil pressure-oil circuit resonance frequency relationship curve is plotted. Figure 3 As shown, the oil pressure-oil circuit resonance frequency relationship curve is an upward-sloping straight line, indicating that the oil circuit resonance frequency and oil pressure are linearly positively correlated.

[0056] In one embodiment, when the target oil-air content is one, the oil pressure avoidance range is determined based on the relationship curve between the solenoid valve operating frequency and the resonant frequency of each oil pressure-oil circuit, specifically including:

[0057] The oil pressure corresponding to the solenoid valve's operating frequency in the oil pressure-oil circuit resonance frequency relationship curve is determined as the resonance oil pressure.

[0058] Obtain the upper limit oil pressure deviation and the lower limit oil pressure deviation. Subtract the lower limit oil pressure deviation from the resonance oil pressure to obtain the lower limit of oil pressure avoidance. Add the upper limit oil pressure deviation to the resonance oil pressure to obtain the upper limit of oil pressure avoidance.

[0059] Specifically, such as Figure 4 As shown, the oil pressure-oil circuit resonance frequency relationship curve of the target oil air content R is related to the solenoid valve operating frequency F. SOL The oil pressure P corresponding to the intersection point Res The upper and lower limits of hydraulic pressure are for resonance. The upper and lower limits of hydraulic pressure deviation mainly consider the control deviation of the hydraulic circuit or the deviation of equipment manufacturing, and are set according to the actual situation of the target hydraulic circuit.

[0060] After determining the resonant oil pressure in this embodiment, considering the deviation of the hydraulic circuit, the lower limit oil pressure deviation A and the upper limit oil pressure deviation B of the resonant oil pressure are respectively used to obtain the lower limit oil pressure avoidance P. Res -A and hydraulic pressure clearance limit P Res+B, the oil pressure range between the lower limit and the upper limit of oil pressure avoidance is the oil pressure avoidance range.

[0061] In one embodiment, when the target oil-air content is two or more, the oil pressure avoidance range is determined based on the relationship curve between the solenoid valve operating frequency and the resonant frequency of each oil pressure-oil circuit, specifically including:

[0062] The oil pressure corresponding to the working frequency of the solenoid valve in each oil pressure-oil circuit resonance frequency relationship curve is determined as the resonance oil pressure. The maximum and minimum values ​​in the resonance oil pressure are determined as the upper limit resonance oil pressure and the lower limit resonance oil pressure, respectively.

[0063] Obtain the upper limit oil pressure deviation and the lower limit oil pressure deviation. Subtract the lower limit oil pressure deviation from the lower limit resonance oil pressure to obtain the lower limit of oil pressure avoidance. Add the upper limit oil pressure deviation to the upper limit resonance oil pressure to obtain the upper limit of oil pressure avoidance.

[0064] Specifically, taking the determination of the air content in two target engine oils as an example, such as... Figure 5 As shown, the target engine oil air content R L and R H The oil pressure-oil circuit resonance frequency relationship curve and the solenoid valve operating frequency F SOL The oil pressure P corresponding to the intersection point Res-L and P Res-H For resonant oil pressure, where P Res-L P is the lower limit resonance oil pressure. Res-H The upper limit is the resonance oil pressure. The lower limit resonance oil pressure is deviated downwards by a deviation A from the lower limit oil pressure to obtain the lower limit oil pressure avoidance P. Res -A, deviating the upper limit resonance oil pressure upwards from the upper limit oil pressure deviation B, obtains the upper limit oil pressure avoidance P. Res +B takes into account the deviation of the hydraulic circuit and can ensure that resonance noise does not occur.

[0065] In one embodiment, determining the target oil pressure range based on the oil pressure avoidance range specifically includes:

[0066] Obtain the upper and lower limits of the hydraulic circuit using oil pressure;

[0067] The target oil pressure range is defined as the oil pressure range between the upper limit of the oil pressure used and the upper limit of the oil pressure avoidance, and the oil pressure range between the lower limit of the oil pressure avoidance and the lower limit of the oil pressure used.

[0068] Specifically, each hydraulic circuit has a corresponding upper and lower limit operating oil pressure. The normal operation of the hydraulic circuit can only be guaranteed when the oil pressure falls between the lower and upper limits. This embodiment avoids the oil pressure avoidance range by selecting the oil pressure range between the upper and lower limits as the target oil pressure range, and the oil pressure range between the lower limit and the lower operating oil pressure. Within the target oil pressure range, the resonant frequency that resonates with the solenoid valve frequency is avoided, thus preventing resonance noise.

[0069] The upper and lower operating hydraulic pressures include a preferred operating hydraulic pressure range within which the hydraulic circuit operates optimally. Preferably, the target hydraulic pressure range can be defined as the overlap between the upper operating hydraulic pressure to the upper hydraulic pressure clearance limit and the lower hydraulic pressure clearance limit and the lower operating hydraulic pressure, and the preferred operating hydraulic pressure range.

[0075] Step S605: Determine the oil pressure corresponding to the working frequency of the solenoid valve in the oil pressure-oil circuit resonance frequency relationship curve as the resonance oil pressure.

[0077] Step S607: Determine the oil pressure corresponding to the working frequency of the solenoid valve in each oil pressure-oil circuit resonance frequency relationship curve as the resonance oil pressure, and determine the maximum and minimum values ​​in the resonance oil pressure as the upper limit resonance oil pressure and the lower limit resonance oil pressure, respectively.

[0078] Step S608: Obtain the upper limit oil pressure deviation and the lower limit oil pressure deviation. Subtract the lower limit oil pressure deviation from the lower limit resonance oil pressure to obtain the lower limit of oil pressure avoidance. Add the upper limit oil pressure deviation to the upper limit resonance oil pressure to obtain the upper limit of oil pressure avoidance.

[0080] Step S610: Determine the target oil pressure range as the oil pressure range between the upper limit of oil pressure used and the upper limit of oil pressure avoidance, and the oil pressure range between the lower limit of oil pressure avoidance and the lower limit of oil pressure used.
