Research On Intelligent Three-Connect-Brake-Spring Examiner

Railway, the national economic artery, is an important transportation method for economic construction and living necessity supply. With the flourish development of railway transportation, there is an increasing demand for the increment of train's length, weight and load, and the velocities of trains are continually increased. These demands can not come true without brake of excellent properties and high reliability.The core parts of trains brake system is Three-Connect-Brake. hence the examine quality of it has been emphasized to a higher level. The movements and locations of Three-Connect-Brake are modulated by its inner springs, so that the examine quality of the springs determines the examine quality of, and which exerts a great influence on the running of a train.Intelligent Three-Connect-Brake-Spring Examiner is a new survey instrument especially designed for the railway vehicles examine and repair department, it overcomes the disadvantages such as complex program in spring examine, too many manpower involved and lower automatic degree, and so on. Spring examiner uses the 89C51 single chip processor as survey core, measures the spring's elasticity and height by means of force sensor and displace sensor, then automatically judges the spring's type, chooses measurement project, measures data of a spring, estimates performance of a spring, and can communicates to a upper computer via serial port, and realizes the automatically examination of many brake springs by an examiner.
