[0044] The core of the present invention is to disclose a cooling module test vibration method to reproduce the real failure mode of the test field and verify the reliability and durability of the cooling module under actual working conditions.

[0045] Another object of the present invention is to disclose a cooling module vibration test device.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figure 3 As shown, an embodiment of the present invention discloses a cooling module vibration test method, comprising the following steps:

[0048] S1, collecting cooling module road spectrum;

[0049] The cooling module 7 is installed on the vehicle according to the use conditions, and the acceleration signal of the vehicle during driving on the test field is collected by the acceleration sensor, wherein the cooling module 7 includes a condenser, a fan, a radiator, etc.

[0050] S2, obtaining the maximum acceleration value of the test field;

[0051] Collect multiple groups of cooling module road spectra, calculate the average value of the maximum acceleration of the multiple groups of cooling module road spectra collected, and use it as the maximum acceleration of the test field. In order to make the maximum acceleration of the test field closer to the actual working conditions, the collected cooling module road spectra include at least three groups. Check and analyze the multiple groups of cooling module road spectra collected, remove outliers, and ensure that the collected acceleration signals are normal. Then, count the maximum acceleration of each group of cooling module road spectra collected, and calculate the average value of the maximum acceleration of each group of cooling module road spectra as the maximum acceleration of the test field. ‌

[0052] S3. Implement vibration endurance test;

[0053] The cooling module 7 is removed from the vehicle and installed in the cooling module vibration test device to perform a vibration endurance test. The acceleration of the cooling module vibration test device adopts the maximum acceleration of the test field obtained in step S2. In order to simulate the actual vehicle state of the cooling module 7, the installation method of the cooling module 7 is the same as that of the installation on the vehicle, wherein the condenser and the radiator are filled with room temperature water and then sealed, simulating the weight of the refrigerant in the condenser and the antifreeze in the radiator when the vehicle is driving.

[0054] The cooling module vibration test method disclosed in the embodiment of the present invention first collects the cooling module road spectrum, takes the maximum acceleration of the test site as the acceleration of the cooling module vibration test device, and verifies the reliability and durability of the cooling module 7 under actual working conditions through the cooling module vibration test device, which helps to discover potential faults early and repair or improve them in advance. Compared with the prior art, the cooling module vibration test method disclosed in the embodiment of the present invention can reproduce faults under the road conditions of the test site, and the test has good repeatability. Compared with the prior art of installing the cooling module on the whole vehicle and conducting a vibration durability test in the test site, the cooling module vibration method disclosed in the embodiment of the present invention only needs to collect several groups of road spectra of the whole vehicle in operation in the test site, and conduct a vibration test through the cooling module test device, without completing the entire process of the vibration durability test of the whole vehicle, which can shorten the test cycle, save manpower, and reduce costs.

[0055] In some specific embodiments, Figure 1 As shown, the cooling module vibration test device includes a vibration platform 4, a hydraulic servo actuator 3, a signal acquisition system 9 and a control system.

[0056] Among them, the vibration platform 4 is used to carry the cooling module 7, and a platform acceleration sensor 6 is provided on the vibration platform 4 to measure the acceleration of the vibration of the vibration platform 4. The platform acceleration sensor 6 is connected to the signal acquisition system 9, and the signal acquisition system 9 is used to collect vibration signals. The control system generates a driving voltage signal and inputs it into the hydraulic servo actuator 3 to drive the vibration platform 4 to vibrate. The signal acquisition system 9 transmits the vibration signal detected by the sensor 6 to the control system to realize the vibration control of the vibration platform 4.

[0057] Specifically, the vibration platform 4 is mounted on the piston rod of the hydraulic servo actuator 3. A fixing fixture 5 is mounted on the vibration platform 4, and the cooling module 7 is mounted on the fixing fixture 5.

[0058] The cooling module vibration test device disclosed in the embodiment of the present invention has a simple structure and is easy to operate. Compared with the MASTABLE road simulation durability equipment used in the prior art, the cost can be reduced. The method of using the cooling module vibration test device is not affected by roads and personnel, has good repeatability, and is convenient for on-site observation, analysis and adjustment.

[0059] In some specific embodiments, Figure 5 As shown, step S3 specifically includes the following steps:

[0060] S31, installing the cooling module 7 on the vibration platform 4;

[0061] In order to ensure that the vibration test is closer to the situation during the vehicle driving, the cooling module 7 is fixed on the vibration platform 4 according to the actual installation method on the vehicle.

[0062] S32, installing the cooling module acceleration sensor 8 on the cooling module 7;

[0063] The cooling module acceleration sensor 8 is installed on the cooling module 7, and the cooling module acceleration sensor 8 is connected to the signal acquisition system 9, so that the acceleration signal of the cooling module 7 during the vibration test measured by the cooling module acceleration sensor 8 is uploaded to the control system.

[0064] S33, the control system sends a preset vibration signal to the hydraulic servo actuator 3, and collects the response signals of the platform acceleration sensor 6 and the cooling module acceleration sensor 8, so as to compare them with the extreme values ​​and main frequencies of the acceleration signal data collected in the test field, and to track the acceleration of the corresponding position of the cooling module 7 when a fault or abnormal information occurs.

[0065] Specifically, a segment-controlled swept-frequency endurance test method is used to carry out the vibration test.

[0066] Furthermore, the preset vibration signal specifically includes: within the first preset frequency range, the vibration platform 4 vibrates according to the preset amplitude and lasts for the first preset time; within the second preset frequency range, the vibration platform 4 vibrates according to the maximum acceleration of the test field obtained and lasts for the second preset time, and the first preset time and the second preset time are one cycle. Among them, the lower limit value of the second preset frequency range is equal to the upper limit value of the first preset frequency range. That is, when the frequency is low, the equal amplitude control mode is adopted, and when the frequency is high, the equal acceleration control mode is adopted. This method can meet the needs of swept frequency vibration and ensure the safety of equipment operation. At the same time, the segmented control method is convenient for operation control and can improve test efficiency and accuracy.

[0067] Furthermore, the preset amplitude is determined according to the vibration frequency when the vibration platform 4 reaches the maximum acceleration of the test field and the maximum acceleration of the test field. Specifically, the acceleration, frequency and amplitude satisfy the following formula: a=(2πf)²A(1), where a is acceleration, unit is m / s 2 ; f is the frequency, unit Hz; A is the amplitude, unit m. The cooling module vibration test device is debugged on site to determine the frequency when the vibration platform 4 reaches the maximum acceleration of the test field, which is recorded as the first frequency. The amplitude is calculated based on the first frequency and the maximum acceleration of the test field, which is the preset amplitude.

[0068] Furthermore, if Figure 4 As shown, step S1 specifically includes the following steps:

[0069] S11, arranging acceleration sensors;

[0070] Acceleration sensors are arranged on the cooling module 7 and the bracket of the whole vehicle respectively, and the acceleration of the cooling module 7 and the bracket of the whole vehicle are obtained respectively during the driving of the whole vehicle in the test field. Specifically, the specific setting position of the acceleration sensor on the cooling module 7 includes the top of the cooling module 7 and the connection position of the cooling module 7 with the buffer rubber sleeve and rubber suspension for vibration reduction. Among them, the bracket of the whole vehicle includes the fixed bracket of the cooling module 7 and the bracket of the whole vehicle body.

[0071] S12, obtaining the acceleration of the vehicle during driving;

[0072] The vehicle with the cooling module 7 installed is driven according to the preset counterweight, preset route and preset speed, and the acceleration of the cooling module 7 and the bracket is obtained respectively through the acceleration sensor. In order to ensure the effectiveness of the collected cooling module road spectrum and reduce the test cycle, after collecting a set of cooling module road spectrum each time, it is necessary to check whether the cooling module road spectrum is valid in time. Specifically, the effectiveness of the cooling module road spectrum can be judged according to the presence or absence of the acceleration signal, symmetry, frequency and phase corresponding to the acceleration signal, etc. At the same time, the sensor should be checked in time to see if it is loose or falling off, so as to ensure the effectiveness of the collected cooling module road spectrum.

[0073] On the basis of the above embodiment, in step S2 , the maximum test field acceleration values ​​of the cooling module 7 and the vehicle support are calculated respectively, wherein the maximum test field acceleration value of the vehicle support is used as the acceleration value of the vibration platform 4 .

[0074] In order to make the vibration test closer to the actual working conditions and fully simulate the vibration impact on the cooling module 7 during driving, in the cooling module vibration test, the installation position of the cooling module acceleration sensor 8 on the cooling module 7 is the same as the installation position of the acceleration sensor on the cooling module 7 when the cooling module road spectrum is collected in step S1, and it is preferably installed on the top of the cooling module 7.

[0075] In some specific embodiments, Figure 1 As shown, the control system includes a main control machine 1 and a controller 2 , the main control machine 1 and the controller 2 are connected via a signal line, the controller 2 and the hydraulic servo actuator 3 are connected via a signal line, and a signal acquisition system 9 is connected to the controller 2 .

[0076] In some specific embodiments, the cooling module vibration test device also includes a shooting system. Specifically, the shooting system shoots the entire vibration test process of the cooling module 7 to record the changes of the cooling module 7 during the entire vibration test process, so as to facilitate timely tracing when a failure occurs in the cooling module 7.

[0077] In the cooling module vibration test method disclosed in the embodiment of the present invention, the vibration mode of the vibration platform 4 is sinusoidal vibration, the vibration frequency is 0.5 Hz-80 Hz, the period is 500 s, and the vibration test lasts for at least 8 hours.

[0078] For ease of understanding, the following is a specific example in which the vibration mode is sinusoidal vibration and the maximum acceleration of the test field is 50 m / s. 2 , one cycle is 500s. In one cycle, the loading frequency of the vibration platform 4 is swept from 0.5Hz to 80Hz. When the frequency is 0.5Hz, the amplitude A is calculated by formula (1): 0.5Hz=5m. Since the hydraulic servo actuator 3 cannot reach such a large amplitude, it is necessary to debug the hydraulic servo actuator 3 on site. The hydraulic servo actuator 3 can only reach the maximum amplitude of 50m / s at 13Hz. 2 The acceleration of normal vibration is calculated according to formula (1). The amplitude A at this time is 13Hz =0.0075m (i.e. 7.5mm), so the preset vibration signal is: when the vibration frequency is 0.5Hz~13Hz (60s), the vibration platform 4 maintains the amplitude A at 7.5mm for 60s, and the acceleration rises from low to 50m / s 2 ; Then when the vibration frequency is 13Hz~80Hz, maintain the acceleration at 50m / s 2 Unchanged, duration 440s, as follows Figure 2 As shown in the figure, the horizontal axis represents the duration, and the vertical axis represents the amplitude. The preset vibration signal with a period of 500s generated above drives the vibration platform 4 cyclically for at least 8 hours, that is, the endurance test is completed.

[0079] During the vibration test, always pay attention to the status of the cooling module 7 and the vibration platform 4. If there is any abnormality, the test should be stopped immediately. After the test is completed, first check whether there is any damage to the components and whether the fasteners of the cooling module 7 are loose. After the test is completed, the cooling module 7 shall not have defects such as cracks, desoldering, and leakage.

[0080] In addition, an embodiment of the present invention further discloses a cooling module vibration platform test device, which is the above-mentioned cooling module test device, and has a simple structure and is easy to operate.
