Problems solved by technology
When the size gap of the working environment of the sealing ring can be changed, due to the creep characteristics of the elastic material, the compression gap will continue to decrease under constant load compression, and the data obtained by using a fixed height limit will be biased

The invention provides a method and a device for measuring the deformation performance of an automobile sealing ring part. The method comprises the following steps: selecting a sample with a set length from an experimental object sealing ring; the curvatures of an upper pressing plate and a lower pressing plate of the measuring device are adjusted to be matched with the sample; the sample is clamped and compressed through the upper pressing plate and the lower pressing plate for first set time; and after the sample is recovered for a second set time after compression, when the thickness of the measured sample in the compression direction does not reach the set thickness, the test object sealing ring does not reach the standard. The deformation performance of the sealing ring is tested by adopting the adjustable upper pressing plate and the adjustable lower pressing plate, a matched compression clamp does not need to be disassembled according to the change of a sample, and the radian of the pressing plates is controlled by moving, so that the test process is simplified, and the test efficiency is greatly improved; the test process is simple and convenient to operate, the test method is scientific and reasonable, intelligent and accurate displacement control and parameter measurement can be realized, a sample is sampled from a product, the processing time of a standard sample block is saved, and the effectiveness of a detection result is ensured.
Description
technical field [0001] One or more embodiments of this specification relate to the technical field of automobiles, and in particular, to a method and a testing device for measuring the deformation performance of automobile sealing ring parts. Background technique [0002] Automotive sealing products are sealed by interference fit and material elasticity. Therefore, for sealing products, the compression set performance of materials is a key item to evaluate the life and sealing performance of sealing products. From the point of view of material properties, the better the compression set performance, the better the sealing performance. Reduced seal interference due to poor material compression set performance is one of the common factors that lead to seal failure. [0003] The compression set of general rubber and elastomer materials is the data obtained by using the standard test conditions of standard specimens (specimen in GB / T 7759: a cylinder with a diameter of 29mm and ...
