[ Hot Focus on Chemical Machinery and Equipment Network ] The Winter Paralympics officially kicked off on the evening of March 4, 2022
.
With the successful holding of the Winter Olympics, the popularity of ice and snow sports continues to rise
.
Due to the high professional requirements of ice and snow sports, suitable protective gear can effectively avoid sports injuries, and the protective gear market is further expanded
.
Since 2022, the transaction volume of ice and snow equipment has increased by 135% year-on-year, of which the transaction volume of sports protective gear has increased by 41%

Since 2022, the transaction volume of ice and snow equipment has increased by 135% year-on-year, of which the transaction volume of sports protective gear has increased by 41%
.
For ice and snow sports protective gear, many issues such as how effective its protection is and whether its safety can meet the standards determine "success or failure"
.
These issues are the focus of consumers' attention

Recently, the Hebei Quality Inspection (HQI) Ice and Snow Equipment Testing Laboratory, the first comprehensive quality inspection service platform in China to serve the Winter Olympics ice and snow industry, participated by Guangdong Dongguan Hongtu Instrument Co.
, Ltd.
(hereinafter referred to as "Hongtu Instrument") has passed the Acceptance
.
Previously, before the Winter Olympics, Hongtu Instruments delivered four types of protective gear testing instruments , namely the knee pad friction testing machine , the impact strength testing machine, the knee pad impact energy absorption testing machine and the simulated wrist testing machine , to escort the ice and snow sports .
At present, these protective gear testing instruments have been used in SGS laboratory, TUV laboratory, Singapore Intertek and Shenzhen Intertek testing laboratory .

In the process of the birth of a new instrument, talents, methods, equipment and other elements are indispensable
.
The technical breakthrough of equipment is even more difficult
.
It is no exception to the detection equipment for ice and snow sports protective gear, and the development period is difficult
.
Today, a new batch of instruments have come out, which not only make breakthroughs in detection technology, but also help consumers choose suitable protective gear and boost the popularity of ice and snow sports

Scenario simulation method: collect specific data and calculate protection performance
The form of exercise determines the technical indicators of the protective gear
.
However, before the release of the five national standards for ice hockey protective gear, China's ice and snow sports protective gear product standards were in a blank stage, and there was no 3C certification and unified standards for protective gear such as knee pads and elbow pads
.
The protective gear inspection work was once difficult to carry out

Previously, the detection of ice and snow athletes' protective gear mostly cited detection methods and detection instruments of other sports
.
Different motion modes are quite different, and the detection method is not completely universal
.
This situation not only increases the difficulty for consumers to purchase related products, but also brings difficulties to the research of protective gear testing instruments

.
This situation not only increases the difficulty for consumers to purchase related products, but also brings difficulties to the research of protective gear testing instruments
.
In this regard, the researchers of ice and snow detection instruments consulted relevant European standards to interpret the key performance parameters and test requirements of the product
.
After the theoretical research is successfully completed, the researchers comprehensively transform it into the corresponding experimental methods and technical indicators for the detection of the protective gear according to the sports type, use environment and scope of the protective gear
.
Taking the knee pad impact energy absorption testing machine as an example, the researchers used this instrument to simulate the scene of an adult falling on the snow, collect and calculate the data of the knee pad impact energy absorption, and then judge the anti-energy buffer performance of the knee pad.
Impact absorption, penetration resistance, cutting resistance, wearing system stability, etc.
put forward more technical requirements

Low-friction bearings: Alleviate test energy loss and ensure a reasonable test range
The accuracy of the test and the accuracy of the data are very important for inspection and testing
.
In order to ensure the detection accuracy of the machine, researchers will conduct repeated tests many times, and the problem of loss is inevitable
.
For example, in the detection of ice hockey sports protective gear, due to the strong impact and confrontation of the sport, the test equipment needs to use heavy hammer impact multiple times to simulate the impact on the knee when a person falls
.
However, during the drop of the test weight, air resistance and friction will lose part of the energy
.
How to control the energy loss within the standard range is another difficulty

.
In this regard, the researchers used a special low-friction bearing, which can reasonably control the energy loss range compared with ordinary industrial bearings
.
When the friction coefficient is too large, the test program will relatively increase the theoretical test height, and use the extra test height to offset frictional resistance and air resistance loss

Independent acquisition system: grab the instantaneous speed and display the value in real time
In ice and snow sports, ice hockey and short track speed skating are full of instantaneous contact collisions, and success or failure can often be determined in an instant
.
Therefore, the instantaneous guarantee result of grasping the protective gear is very important to ensure the safety of the athlete in time
.
However, the conventional oscilloscope capture time is often used in the previous inspection, and then the time is used to calculate the speed
.
Since the impact collision is usually completed in a few milliseconds, this method is not only time-consuming, but also cannot display the value in real time
.

The host computer test software delivered this time has an independent acquisition system, which can not only display the test speed in real time, but also test the energy and acceleration values and action time
.
The researchers compared the data of the control group to obtain the energy absorption value of the knee brace, thereby testing the safety factor of the knee brace

While the equipment is "online", relevant policies are constantly being improved
.
At the end of 2021, 16 national standards for ice and snow sports goods organized and formulated by the China Stationery and Sports Goods Association were officially released.
The national standard formulation work of the five parts of the safety requirements and experimental methods for elbow, knee and face protection is listed as the key work of the standard to be carried out and completed with priority
