This type of simulation (life) test is to put the finished product into the simulated running conditions, check the actual wear quality and the cumulative number of walking times of the test, and compare it with the actual test of the same product in each part to calculate the wear life of the mountain shoes. It can also be used to test the new type of silicone with the target to determine the suitability of the new type of silicone. The simulated walking (life) test specimen, test method, and record the damage measurement in the case are marked, and the rest is determined. This environmental group is This standard was drafted by: National Quality Supervision and Inspection Center (Hangzhou), Shanghai Stock Footwear Research Institute. The main drafters of this standard are: Yue Jiqian, Tu Shiyan, Fei Huiqin, Feng Xiaogu, Cai Shenghua, Shi Qiong.

3 Definitions
This standard adopts the following definitions Meaning:
3.1 Tests:fonwear
randomly selected products from mass production of qualified products 3-2 pairs of test shoes are taken out from the same batch of products, 3.new
the shoes made of new process materials are compared with the controlled shoes in the test. 3.4 The controlled coatrol
has known its performance characteristics and process, 3.5 Verification
the new single core of the shoes is compared with the controlled shoes, 4 Test Principle
The test simulates walking movement when wearing the shoes, the heel is first in contact with the center of the road, and then the heel is pulled up, and the standing position is bent and the angle is changed by 25-1. During the whole dynamic process, the test part is always under the pressure of the general level and body, which can produce a sense of sitting on the falling surface. In the test of the device, the damage process of the shoes is recorded and compared with the unadjusted shoes of the same batch. To determine whether the shoes are safe to wear, the new letter agency carried out a controlled dynamic analysis to determine the applicability of the new type:

5.1 Simulation It is a device composed of a large sleeping beater, a small beater, an injection beater (for example, tendons), etc., which is effective when driven by an electric motor. The device must maintain the correct contact with the test road surface when the foot is adjusted (see Figure 1) 1-motor: 2-system return vehicle: 3-large group 14-connecting support 1-lift lung 4-small rod: 3-weighted whole test sample
1 simulated walking device
5.2 Adjust the micro-device's center load and the negative inclination of the water friction, simulate the suction on the broken, and walk on the simulated version of the test, 5.3 Adjust the color reduction bricks, the song is also enough, it can simulate male and female, and the weight of the test is measured. 5.4 The speed of the motor is steplessly adjustable, and the speed regulation rate error is 7. The actual speed regulation rate can reach 23 times per minute (double brand). The test is carried out according to the meter. 5.5 The road surface to be tested is 23" or 21U small sandpaper belt (the back of the sandpaper belt is used as an adhesive to stick the label to the twill cloth. The sandpaper belt can be replaced after use. 56 Equipped with a force measurement sensor, which can measure intermittently or continuously. During the simulated walking test, the rate of force between each part of the sole and the road surface. 5.7 The test sample is placed at 90°, the foldable part should be elastically connected, the toe part should have a certain degree of heat, and there is no obvious layer at the connection between the sample and the bottom belt. Test crotch The winter size is 24 for men, 22 for women, 17 for singles. When testing, they can be equipped with appropriate folding, printing, type guide, small... When testing, the size is folding?
5 Sample
: The test rod is various types of mature men's shoes No. 25, women's shoes No. 23, and other subject numbers can be used as required by the school standard) 5.2 Sample quantity, groove method test is one pair, one pair is put on the machine for the specified number of tests, and the other pair is used as a comparison source before and after the test.
5.3 When testing the new type of shoes, one pair of groove controlled shoes is used, and the effect is new type of shoes. Sub-test strips

8.1 Sample preparation: On the bottom of the test shoe, take the bottom axis as the reference, draw a straight line parallel to the naran at a spacing of 10: the double shoe shear load and performance axis multiplied by the variable point as the starting point, the spacing is 12mra, and the card is marked with parallel lines from the upper axis. The model is marked with 1.2, 3-. The fast coordinates are marked with AB... mother marks. At the same time, the wheel base of the test shoe sole is drawn on the square grid with a spacing of m. For the stock certificate (as shown in Figure 2)

3.5 When testing the new type of shoes, the whole frog is changed. 2. The control and style have the right skin change cross ring two corrections to carry out the planned test tight, HGT36111999
8.6 Select the test frequency and the final cumulative number of times, 7 dynamic test machine test,
88 determine the cumulative number of test skins and observe the test situation frequently, and clean : The sample does not show obvious damage, except for the sanding belt and other debris. The continuous test number is stopped at the specified time: If necessary, the inspection should be stopped every 52 times. Record the relatively high points on the recording paper. Remove the biting chips and other debris on the sample. Observe the debonding and damage on the side and back of the instrument. Continue the test until the specified number of tests: 8.9 After the test node, measure, observe and record according to the test requirements. The rubber measurement readings are measured by microscope. The area is measured by using an integrator. The coordinates of the points on the test sheet are recorded. The trend is selected by measuring the line. 9.1 The percentage of wear area is calculated by the formula: X, ()

Specialized modification: As far as possible, the scan that can be measured can be made up for the objective evaluation of the performance of each controlled shoe: and the average value can be used to record the calculated value and the test condition in the test to evaluate the wearer's performance. 10 Test report
