Problems solved by technology

This kind of test is carried out in an ideal environment. The test car ball head is very clean and will not be corroded and damaged by muddy water and dirt. However, during the actual use of the car, there will always be dust attached to the car ball. On the head, especially when driving in a rainy day or in a muddy environment, it is easier to make muddy water and dirt mixed with sediment adhere to the car ball head, which is very corrosive to the car ball head. How about the performance of the car ball head in this environment? Therefore, the present invention will discuss this in detail

Embodiment 1

[0018] figure 1 Shown: a kind of automobile ball end durability test method, described test method comprises the steps:

[0019] ①. In the silt slurry water spraying mechanism, silt and water are mixed in the water storage tank 16 according to the ratio of 50g to 1 liter of water and fully stirred;

[0020] ②. Install the test piece 10, that is, the automobile ball head, on the test frame of the machine 1;

[0021] ③. Adjust the test equipment and adjust the swing test mechanism: the swing angle of the swing test mechanism can be adjusted from 0 to 70°, and the swing angle can be adjusted arbitrarily within this range, and the adjustment accuracy can reach 0.5°; swing The frequency is 0~5Hz; the accuracy of swing frequency adjustment can reach 5%;

[0022] During the test, adjust the swing angle and swing frequency of the swing test mechanism according to the specific test requirements, for example, when the swing angle is 15°, the swing frequency is 5Hz; when the swing angl...

Embodiment 2

[0030] figure 1 Shown: steps ①-③ in this embodiment are the same as embodiment one, only need to readjust the mud slurry water spraying mechanism in step ③, specifically:

[0031] Adjust the mud and mortar water spraying mechanism, the spraying speed is 50ml / s, the spraying method: synchronized with the test process, spraying continuously during the test, from the beginning of the test to the end of the test;

[0032] ④. Set the test cycle to 2 million times;

[0033] ⑤. Simultaneously start the swing test, rotation test and mud slurry water spraying program. When the test cycle reaches the set value, stop the machine and the test is completed.

Embodiment 3

[0035] figure 1 Shown: Steps ①-③ in this embodiment are the same as in Embodiment 1 or Embodiment 2, only need to readjust the mud slurry water spray mechanism in step ③, specifically: the spraying speed is set to 100ml / s, and the spraying method Set as: time-limited spraying, the entire test process only needs to be sprayed once, and the specific spraying time can be set according to the test requirements, such as 5h or 15h or 20h, etc. Of course, the entire spraying time should be shorter than the test time;

[0036] ④. Set the test cycle to 5 million times;

[0037] ⑤. Simultaneously start the swing test, rotation test and mud slurry water spraying program. When the test cycle reaches the set value, stop the machine and the test is completed.

[0038] Above-mentioned test method is accomplished by means of testing equipment, and described testing equipment comprises organic table 1, swing testing mechanism 2, rotating testing mechanism and mud slurry spraying mechanism, an...

Abstract

The invention relates to an automobile ball head durability test method and relates to a test method of automobile parts, comprising the following steps: 1. in a slit slurry water-spraying mechanism, slit and water are mixed in a water storage tank and are fully mixed according to the proportion of 50g / 1 liter of the slit and water; 2. a test piece, that is, an automobile ball head is arranged on a test frame of a machine; 3. test equipment is regulated; 4. the test period is set into from 1,000,000 times to 5,000,000 times; 5. the procedures of swinging test, rotating test and slit slurry water spraying are carried out simultaneously, when the test period reaches the setting value, the machine stops, and the test is finished. The method is used for the durability test of the automobile ball head under the condition that severe environment is simulated, so as to test the using performance of the automobile ball to the maximum extent.

Description

technical field [0001] The invention relates to a test method for auto parts, in particular to a test method for the durability of an automobile ball joint. Background technique [0002] As an important means of transportation, automobiles have been gradually popularized in human life. The safety factor of automobile performance is also an important factor considered by vehicle buyers. The safety factor of a car is also judged by the combination of safety factors of each component of the car. Among them, the automobile ball head is a very important part, and the safety factor of its performance is directly related to the safety factor of the entire car. Therefore, it is very important to test the performance of the automobile ball head, including the durability test. Manufacturers are also very strict on the test of automobile ball joints. The test method generally adopts the structure of swing test or rotation test, and even adopts the method of simultaneous swing test and ...
