Helmet impact testing machine performance characteristics:
1. Using servo motor, servo controller and It's supporting control unit as the drive component, the motor has a long service life.
2. Adopt hollow gear reduction system, low power consumption, low noise, high efficiency and high reliability.
3. Adopt Zhongtai data acquisition carded to keep the accuracy of the test machine unchanged for a long time.
4. Adopting the straight-in type transmission device to make the positioning precision high, long life, low friction, high-speed operation and forward and reverse rotation, so that the whole machine runs translation, displacement, speed accuracy is greatly improved.
5. With position limitation function, it makes some tests with position restriction requirements safer and faster.
6. Extremely wide measuring range, applicable to many national standards.
7. Adopting the integrated design principle, no matter the configuration of the host, modify the corresponding parameters of the computer (the parameters can be permanently retained), no circuit adjustment is needed.
8. High-precision return positioning functioned, which can accurately return to the starting position regardless of the return speed, speed up the would test and improve work efficiency.
9. Common parameter memory function, such as test speeds, so that a boot is in this parameter state, which greatly facilitates the user.
10. Flexible and convenient operation, with two workings modes: constant movement and jog, users can easily set freely to adapt to different occasions or habits.
11. With a variety of protection functions: adjustable upper and lower limit protection, emergency stop protection, etc.

When the helmet impact tester is running, what are the impacts of the environment on its test data?

First, the exclusion of the conditions of the helmet testing machine. During each environmental or reliability test, there are strict regulations on the types, magnitudes, and tolerances of environmental factors, and the environmental factors required for non-tests are excluded from penetration so that during the test or at the end of the test. After judging and analyzing the product failure and failure mode, it provides accurate basis. Therefore, the helmet testing machine is not allowed to attach other environmental stress interference signal to the test product in addition to the specified environmental conditions.

Second, when doing the test, especially the reliability test, his test period is long. When conducting military product tests, the tester often needs to operate the inspection or test work around the site. Therefore, the environmental test equipment must be safe to operate and easy to operate. It is reliable in use and long in working life to ensure the normal operation of the test itself. The various protection, warning measures and safety interlocking device of the test equipment should be perfected and reliable to ensure the safety and reliability of the test personnel, the tested products and the test equipment itself.

Third, the environmental condition parameters can be measured and controlled, the environmental conditions provided by any helmet testing machine must be observable and controllable, not only to limit the environmental parameters within a certain tolerance range, to ensure the reproduction of test conditions Sexual and repetitive requirements, and also from the safety of product testing, to prevent the loss of control of environmental conditions leading to damage to the test product, resulting in unnecessary losses. At present, the accuracy of the parameter tests generally required in various test specifications should not be less than one thirds of the error allowed by the test conditions.

Reproducibility of Environmental Conditions The helmet impact tester is an elusive thing to completely and accurately reproduce the environmental condition in nature in the test chamber. However, within a certain tolerance range, people can correctly and correctly simulate the external environmental conditions experienced by engineering products during use, storage, transportation, and the like. This paragraph is summarized in the language of the project, that is, the environmental conditions (including the platform environment) created by the equipment around the tested product should meet the environmental conditions and tolerances specified in the product tests specification.

V. Reproducibility of environmental conditions A helmet impact tester may is used for multiple tests of the same type of product, and one engineered product may is tested in different environmental test equipment, to guarantee the same product. The comparability of the test results obtained under the environmental test conditions specified in the same test specification necessarily requires the environmental conditions provided by the environmental test equipment to be reproducible. That is to say, the stress levels (such as thermal stresses, vibration stress, electrical stress, etc.) applied to the product under test by the environmental test equipment is consistent with the requirement of the same test specifications.
