Description
Technical field
The present invention relates to a kind of method of test material performance, especially relate to the method for the performance change that a kind of test material soaks in the high temperature transmission oil.
Background technology
In car transmissions, system need to work under the condition of 150 ℃ of temperature, and the housing of these system outsides, the sticks in gap etc. also will directly contact with power transmission oil.In a lot of situations, the housing of kinematic train outside, the sticks in gap etc. cause kinematic train to lose efficacy, thereby cause huge loss due to the transmission oil working environment that is in for a long time high temperature.
So far, not yet there is the test routine of moulding directly to study the performance of various materials in the high temperature transmission oil from raw-material rank, thereby judges which material is fit to the high-temperature oil resistance environment of legacy system.
Summary of the invention
Purpose of the present invention is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of usable range is wide, safe and reliable, cost, test the method for the performance change that test material easily soaks in the high temperature transmission oil.
Purpose of the present invention can be achieved through the following technical solutions:
The method of the performance change that test material soaks in the high temperature transmission oil comprises the following steps:
(1) detect sample sensor mechanical property at room temperature to be tested;
(2) sample sensor to be tested is placed in the pressure test container that is loaded with transmission oil, sample sensor to be tested is immersed in transmission oil, then the pressure test container is placed in explosion-proof stove;
(3) temperature of controlled pressure test container rises to 150 ℃, and control heat time heating time is 500-2000h, and sample sensor to be tested is processed;
(4) take out sample sensor to be tested, cleaning is cooled to room temperature with it behind the surface, then the mechanical property of the sample sensor after processing is tested, also need to test in addition the change of weight, namely complete the test of the performance change that sample sensor soaks in the high temperature transmission oil.
Described mechanical property comprises that pulling strengrth, deflection, bending strength, bending modulus, stretch modulus and weight change.
Described transmission oil is commercially available Dexron-VI level or ATF-212-B.
Compared with prior art, the present invention has the following advantages:
One, usable range is wide: can be used for epoxy, the various materials selections such as plastics are when it must tolerate the ATF high temperature oil and be subject to the condition of work of certain load particularly applicable.
Two, safe and reliable: pressure vessel and anti-riot stove have been adopted in the test in invention, test be all into confirm not have potential safety hazard, the performance of various aspects that the project of experiment has comprised the checking material in high temperature oil and the situation of change of bearing certain stress, guarantees that its effect with long-term use is identical in long period of soaking.
Three, cost is lower: this invention material that do not need a person with the qualifications of a general is molded into final products, and the failtests that carries out system level can verify material, and corresponding cost and time have been saved in screening.
Four, experiment is convenient: the experiment equipment needed thereby easily obtains, even purchase of equipment, also easily operation.
