制动瓦

The high phosphorus cast iron brake is the important components which the railroad vehicles apply the brake, when the work withstands the high temperature, the high press plier pressure therefore requests the organization to be compact, must carry on the strict ultrasonic testing and mechanics and the transformation performance examination, the specification is strict.

高磷铸铁闸瓦是铁道车辆制动的重要零件，工作时承受高温、高压，因此要求组织致密，必须进行严格的超声波探伤和力学及物化性能检验，技术要求严格。

Then the fault forecast in mine hoist to steel wire rope wears away degree, get empty to move time, brake shoe wear away life, brake shoe clearance, remnant presses and brake disk deflection degree adopt Wavelet neural network in this paper, which have the important meaning to guarantee the mine hoist circulate efficiently safety.
