How does a tension meter test the mechanical properties of a car door lock?
How does a tension meter test the mechanical properties of a car door lock? As a device that is currently very popular in the market, the rally meter is also used in many industries. The car looks as if it doesn't match the rally meter. In fact, the rally test is also very much in the automotive industry. Haida instrument for you to do the following explanation:
Car door locks and door holders test methods, according to the national standard GB 15086-2006 requirements, the need to test the mechanical properties of the lock, you need to use a tensile testing machine for testing.
The longitudinal load requirement is that the lock body and the lock assembly of the door lock must be capable of withstanding a longitudinal load of 4440 N in the half-locked position, and capable of withstanding the longitudinal load of 11110 N in the full-lock position, and must not be disengaged; in the lateral load requirements , Full lock position to withstand 8890N load. There are also performance requirements for resistance to inertial forces and door chains.
A tensile tester is required to perform longitudinal load and lateral load tests, respectively, and performance tests are performed in both the half-locked position and the fully-locked position, respectively. Such as lateral load, full locking position test process, the following requirements:
1. The lock body and the lock are installed and fixed on the fixture of the tension machine. For example, under the clamp figure, the pulling force shall be ensured through the center of the engagement surface of the lock body and the lock catch, and the pulling force acts laterally on the lock body and the lock catch along the door opening direction;
2, the lock body and the lock should be in full locking position;
3, start the test machine to apply tension, until the destruction of the sample, to obtain the maximum force value.
How does a tension meter test the mechanical properties of a car door lock? The above is the test of the car's door lock performance by the rally meter. The method is also quite simple. I believe that the user is familiar with the car after a period of proficiency.
