Automatic Test System tensile test LZC


,[link widoczny dla zalogowanych], Press method: the first section of SF · 2B amplifier withered zero button to LZC-1 show \showed an increase in 0.5DDV,[link widoczny dla zalogowanych], shown as the number of observations LZC1 code (this time on the stress value of 50kN),[link widoczny dla zalogowanych], and then increase 0.0500V (this time on the stress value lOOkN),[link widoczny dla zalogowanych], continue to observe the LZC-i display .... Approximately zero potentiometer to adjust the range of 2V,[link widoczny dla zalogowanych], F can be calculated with this method is 33.33 yds / kN. 6.3 Mechanical tests <1) ④ Considerations before testing samples for the test, the first source of the material according to preliminary information provided by the judge about how much strength? Load is how much? To determine the calibration coefficients, and x-F Y recorder-axis gain (vertical axis according to the standard required a high degree of choice) to ensure adequate sensitivity. ② According to the measured performance option extensometers, if you believe not. , Select the D level and above should be measured extensometer. . , Enter the deformation calibration factor e, set one (key). ③ If satisfied that the material s, but not during the test fixture and sample news slip occurs, you can not find the argument Chung count as, asu, O'SL and bite. This is one of the salient features of the instrument to slip if the load on the sample at maximum load below 40, LZC one can still accomplish this function. '* 36. Physical testing I991 No. 6 --- one by one - one by one - one by one for a ~ ~ ~ ~ ... a --- a - a ④ not obvious for the physical yield point where I do not know whether Sheng physical yield point Bl stretch material accounting side of the recommended test. ⑤ the requirements of testing and contingency-related, such as Juan o. n, o. z, s etc. must be measured with the extensometer. ⑥ are not familiar with the material, it is proposed x-Y recorder stop line painted at the same time to compare and reservations. (2) test in accordance with the requirements of test input F, 8, and demand performance and the parameters of the session basis by Kai (key) into the test. At this point LZC-l display will show the tensile stress rate, adjust the throttle to maintain the standards values of stress rate (yield ago 3-3ON/mm · st), a sharp drop when the stress rate that material into the yield condition, and have a yielding stage, if not the whole curve and d, d. , D. Extensometers and other indicators can be removed, continue to stretch until the specimen fracture. . Specimen fracture, the computer automatically calculate and display the results of the state cycle. If you want to find a, according to article 5 'section of LZC-l Introduction to Test and application. If the data you are approved, press Enter, print, until the end of an experiment after all the tests, the list send the report to print. LZC tensile test system for automatic testing, mechanical testing methods involving standard metal materials, mechanical properties of experimental techniques, force and strain of the automated test and measurement, and computer applications. Its successful development is the result of many vigorous cooperation is the author and Liangxing Bang, Zheng Jianping, WANG Yue Yang Jianhua group, Lee and other comrades the right to work closely together to complete the. Finally, the author of the work done to help other comrades had to extend my heartfelt thanks to the quality of test specimens Liu Zhong c 'stingy 【study of total hip Steel Beijing 1DOO8l' sample test data directly affect the quality of the accuracy and reliability. Therefore, the sample processing must be carried out strict quality inspection to ensure the finished sample size, condition, roughness standard requirements and test requirements. . (1) geometry tests: geometric dimensions, including length, diameter, curvature flatness, straightness, roughness, roundness, and ellipticity are not cylindrical, conical degree, degree of saddle-shaped drum, bending degree, and surface, the amount of geometric tolerance and other sample size guillotine appropriate measurement tools should be used for special sizes to be equipped with special tools, such as projectors, side grab instruments, tools, microscopes, precision flat, blade-like flat-foot radius of the pull and so on. Test should be measured through a variety of measuring tools. Measurement readings should be read carefully, if necessary, to repeat the measurements. To ensure the finished size measured after each process should be examined one by one. (2) Surface roughness inspection; work in particular parts of the sample surface roughness on the test results greatly. Finished surface roughness of the sample drawings must meet the processing requirements and standards. After inspection and testing should be used roughness of the surface of coarse sugar standard model, and coupled with 3-5 times the magnifying glass for examination. At the same time, also often used to inspect surface roughness tester. (3) morphological examination: sample process flow of the finished product a great influence on the specimen. Therefore, the response to each; Emirates investigation process and finished goods scratch the surface of sample card hurt Gui, crack extreme cold, heat and other processes checks and finished checks.
