材料及力学性能均提出了新的要求，如高温下疲劳与蠕变的交互作用、热机械疲劳、 The rapid development of modern industry and science and technology has put forward new requirements for the materials and mechanical properties of new pressure transmitters , such as the interaction between fatigue and creep at high temperatures, thermomechanical fatigue,
Deformation and fracture behavior of structural ceramics, deformation resistance of composites at ultra-high temperature, etc., and the rapid development of microelectronic technology has also provided favorable conditions for the development of material testing technology.
The First World War promoted the development of many technologies and also put forward higher requirements for the mechanical properties of materials. Requires lower density and stronger materials to make aircraft, new aircraft
的研究领域，以深人研究各种 Engines and rockets, as well as other military machinery and equipment. After the war, 'these technical achievements began to be converted to civilian use, thereby broadening the research field of new and useful pressure transmitters to deeply study various
Static and dynamic properties of practical materials. For example, in the early 1950s, the study of "Low Cycle Fatigue" began, and a new concept of fracture mechanics was introduced in 1953.
Later, new ideas of fatigue test of random load spectrum were introduced.
In order to meet the needs of the above-mentioned new material mechanical performance testing, while developing a fully digitally controlled material test system, it is also necessary to develop test systems, heating and cooling systems in various special environments,
Booster system and rapid test system and its dedicated software.
In 1879, Friedrich Ole published a monograph on the study of train wheels and axles, which opened up a new field of side test technology research-the era of fatigue strength. Later, academic researchers who tested the machinery
Employees and manufacturers are meticulous for their mutual benefit
In the early days of the European Industrial Revolution, material testing technology was limited to the use of less flexible machinery to evaluate the strength of materials when they were stretched, compressed, or flexed. These tests are static tests.
They are converted from weighing machines. These devices are not used to measure mass, but use mass basins as a means of testing the strength of materials. The first pressure transmitter manufacturers of this testing machine appeared in the 19th century.
In the early days of Germany, Germany at that time also became an important center for the development of mechanical engineering technology.
In order to explain the characteristics of new materials and study material fracture theory, the test process is required to be more complicated and the test accuracy is required to be more accurate. Since the Second World War,
It is in North America, so a new generation of material testing technology and testing equipment has gradually developed in North America.
材料的力学行为是材料的重要使用性能，即通过对工程材料在(动静)载荷、(高低)温度和(腐蚀)环境等因素共同作用条件下的变形、损伤、 The mechanical behavior of the material of the pressure transmitter is an important performance of the material, that is, the deformation, damage,
Research on fatigue and fracture, comprehensively and profoundly understand the failure process and mechanism of materials, determine various indicators of material mechanical properties, propose ways to improve mechanical properties, and guide the research and development of new materials to meet
Need for industrial development.
Cooperate to develop a batch of new test equipment, which greatly improves the test conditions and also improves the test methods. This is also the era when some well-known testing machine companies in Europe are showing their skills.
There are Rosenhausen, Amsler, Moore and Feidenfu. The test machinery designed by these manufacturers is marketed in Europe, enabling many basic research work to proceed smoothly, resulting in better materials and better
The product. The test equipment at that time was mainly mechanical, and its inherent design limited the evaluation of the dynamic properties of the material.
