ばね試験機は、基準に従って厳密に変位を検出します。これにより、ばねがプレッシャープレート上の異なる場所に配置された場合でも、試験力が基本的に同じであることが保証され、試験力の全範囲内にあることが保証されます。いかなる荷重によっても荷重センサーが移動することはありません。シェン。また、ばね試験機の荷重方法が試験結果に与える影響も無視できません。初期ローディング方式では、主に通常の AC モーターを使用してトランスミッション システムを駆動し、ローディング速度を調整することができません。バネなどの弾性コンポーネントの場合、反発応力が存在するため、高速圧縮中に自動的に収集されるデータは、低速圧縮または静的圧縮中に収集されるデータとは異なります。データは大きく異なります。現在、AC サーボ速度制御システムなどの可変速システムは、ばねの動作状態を現実的にシミュレートし、この状態でのばねの内部応力を正確に測定してばね設計の基礎を提供するためによく使用されています。
The spring testing machine detects the displacement strictly in accordance with the standards, which can ensure that the test force is basically the same when the spring is placed in different places on the pressure plate, ensuring that within the full range of the test force, any load will not cause the load sensor to shift. Shen. In addition, the impact of the loading method of the spring testing machine on the test results cannot be ignored. The early loading method mainly used ordinary AC motors to drive the transmission system to load, and the loading speed cannot be adjusted. For elastic components such as springs, due to the existence of rebound stress, the data automatically collected during fast compression is different from the data collected during slow compression or static compression. The data vary greatly. Nowadays, variable speed systems such as AC servo speed control systems are often used to realistically simulate the working state of the spring and truly measure the internal stress of the spring in this state to provide a basis for spring design.
With the development of computer technology, the shortcomings of relatively simple functions of single-chip microcomputers have been improved by microcomputers. Intelligent function setting expert system, parameter selection, database, clear window Chinese interface, and simple mouse operation make the spring testing process the most efficient. The ideal state has become possible, and the level of intelligence has been greatly improved. The operator can measure and control according to any preset mode by just clicking the mouse, and set different test speeds and parameters during the test. , so that the test mode and the entire test process can be controlled according to people’s will, the test curve and test data can be displayed in real time, the test data can also be calculated, organized, and output according to industry standards or corporate standards, and past test processes and tests can also be Query the results, and the powerful calculation and mathematical statistics functions replace the complicated work in the past, greatly reducing human labor.
In addition, the application of computer network technology will combine the detection control machine (referred to as the lower computer) with the main control computer of the computing center (referred to as the upper computer) to realize the transmission, processing and comprehensive management of test data. In the central laboratory, The upper computer implements comprehensive management of the lower computer fleet.
