[0037] The specific implementation of the present application is further described below with reference to the accompanying drawings.

[0038] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the application.

They are relative concepts and may change accordingly according to their different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above-mentioned in this application can be understood according to the specific circumstances.

[0041] The hydraulic circuit oil pressure setting method in the embodiment of the present application is as follows: Figure 1 As shown, the following steps are included:

[0042] Step S101: determining at least one target oil-air content according to hydraulic circuit requirement data.

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

[0044] Step S103: Acquire the solenoid valve operating frequency, and determine the oil pressure avoidance range according to the relationship curve between the solenoid valve operating frequency and each oil pressure-oil circuit resonance frequency.

[0045] Step S104: determining a target oil pressure range according to the oil pressure avoidance range.

[0046] Specifically, the oil circuit resonance frequency of the hydraulic circuit is related to the oil-air content and the oil pressure. Different hydraulic circuits have different oil-air content due to different oil circuit layout characteristics. This application first determines at least one target oil-air content that meets the target hydraulic circuit based on the hydraulic circuit requirement data, and determines the corresponding oil pressure-oil circuit resonance frequency relationship curve for each target oil-air content. Then, the solenoid valve operating frequency of the target hydraulic circuit is obtained. Since resonance noise will occur when the solenoid valve operating frequency is the same as the oil circuit resonance frequency, combining the solenoid valve operating frequency with each oil pressure-oil circuit resonance frequency relationship curve can determine the oil pressure range where the frequency may resonate. This oil pressure range is used as the oil pressure avoidance range. When setting the oil circuit oil pressure, the oil pressure avoidance range can be avoided to solve the problem of resonance noise in the hydraulic circuit.

[0047] The embodiment of the present application first determines the target oil-air content, then determines the corresponding oil pressure-oil circuit resonance frequency relationship curve, and determines the oil pressure avoidance range in combination with the solenoid valve operating frequency, thereby avoiding 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 according to the hydraulic circuit requirement data specifically includes:

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

[0050] At least one target oil-air content is determined within an oil-air content range.

[0051] Figure 2 An example of an oil temperature-air content curve is shown. The oil air content gradually increases with the increase of the oil temperature, and the rate of increase gradually decreases. For different hydraulic circuits, different oil temperatures are used. The embodiment of the present application obtains the oil temperature range used by the target hydraulic circuit, substitutes the oil temperature range into the oil temperature-air content curve, and determines the corresponding oil air content range.

[0052] The target oil-air content can be any value in the oil-air content range. Preferably, the upper limit value and the lower limit value of the air content in the oil-air content range can be selected as the two target oil-air contents, so that the most accurate oil pressure avoidance range can be obtained; 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 HFor the target oil-air content, determine two corresponding oil pressure-oil circuit resonance frequency relationship curves as follows Figure 3 shown.

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

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

[0055] In the embodiment of the present application, based on the target oil circuit layout characteristics of the target hydraulic circuit, combined with the oil foaming characteristics, the oil pressure-oil circuit resonance frequency relationship curve corresponding to each target oil air content is determined, and the oil air content in the target hydraulic circuit can be controlled to be the target oil air content in combination with the oil foaming characteristics, and the oil circuit resonance frequency corresponding to the circuit under different oil pressures is measured. By measuring the oil circuit resonance frequency data under multiple oil pressures, the oil pressure-oil circuit resonance frequency relationship curve is drawn. Figure 3 As shown, the oil pressure-oil circuit resonance frequency relationship curve is a straight line inclined upward, which shows that the oil circuit resonance frequency and the 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 according to the relationship curve between the solenoid valve operating frequency and each oil pressure-oil circuit resonance frequency, specifically including:

[0057] Determine that the oil pressure corresponding to the solenoid valve operating frequency in the oil pressure-oil circuit resonance frequency relationship curve is the resonance oil pressure;

[0058] Obtain the upper and lower oil pressure deviations, subtract the upper oil pressure deviation from the resonance oil pressure to obtain the lower oil pressure avoidance limit, and add the lower oil pressure deviation to the resonance oil pressure to obtain the upper oil pressure avoidance limit.

[0059] Specifically, if Figure 4 As shown in the figure, the oil pressure-oil circuit resonance frequency relationship curve of the target oil-air content R and the solenoid valve operating frequency F SOL The oil pressure corresponding to the intersection point is P Res The upper limit oil pressure deviation and the lower limit oil 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 the resonance oil pressure is determined in the embodiment of the present application, the deviation of the hydraulic circuit is considered, and the resonance oil pressure deviation A from the lower limit oil pressure and the deviation B from the upper limit oil pressure are respectively obtained to obtain the oil pressure avoidance lower limit P Res -A and oil pressure avoidance upper limit P Res+B, the oil pressure range between the oil pressure avoidance lower limit and the oil pressure avoidance upper limit 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 according to the relationship curve between the solenoid valve operating frequency and each oil pressure-oil circuit resonance frequency, specifically including:

[0062] Determine that the oil pressure corresponding to the solenoid valve operating frequency in each oil pressure-oil circuit resonance frequency relationship curve is the resonance oil pressure, and determine that the maximum value and the minimum value of the resonance oil pressure are the upper limit resonance oil pressure and the lower limit resonance oil pressure respectively;

[0063] Obtain the upper and lower oil pressure deviations, subtract the lower oil pressure deviation from the lower resonance oil pressure to obtain the oil pressure avoidance lower limit, and add the upper oil pressure deviation to the upper resonance oil pressure to obtain the oil pressure avoidance upper limit.

[0064] Specifically, take the determination of two target oil-air contents as an example, such as Figure 5 As shown, the target 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 corresponding to the intersection point is P Res-L and P Res-H is the resonant oil pressure, where P Res-L is the lower limit resonance oil pressure, P Res-H The lower limit resonance oil pressure is deviated downward from the lower limit oil pressure deviation A to obtain the oil pressure avoidance lower limit P Res -A, the upper limit resonance oil pressure deviates upward from the upper limit oil pressure deviation B to obtain the oil pressure avoidance upper limit P Res +B, taking into account the deviation of the hydraulic circuit, can ensure the occurrence of resonance and abnormal noise.

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

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

[0067] The oil pressure range between the upper limit use oil pressure and the oil pressure avoidance upper limit and the oil pressure range between the oil pressure avoidance lower limit and the lower limit use oil pressure are determined as the target oil pressure range.

[0068] Specifically, each hydraulic circuit has a corresponding upper and lower limit oil pressure, and the normal operation of the hydraulic circuit can only be guaranteed when the oil pressure is between the lower and upper limit oil pressures. The embodiment of the present application avoids the oil pressure avoidance range, and selects the oil pressure range between the upper limit oil pressure and the upper limit oil pressure avoidance, and the oil pressure range between the oil pressure avoidance lower limit and the lower limit oil pressure as the target oil pressure range. Within the target oil pressure range, the resonant frequency that resonates with the solenoid valve frequency is avoided, and the occurrence of abnormal resonance sound is avoided.

[0069] The upper limit oil pressure and the lower limit oil pressure include a preferred oil pressure range, within which the hydraulic circuit works better. Preferably, the oil pressure range between the upper limit oil pressure and the oil pressure avoidance upper limit and the oil pressure range between the oil pressure avoidance lower limit and the lower limit oil pressure and the preferred oil pressure range can be determined as the target oil pressure range.
