The invention discloses a rapid motor train unit vehicle stability detection device which comprises a box body, a cover plate arranged on the box body, a fixed base arranged in the box body, a controlchip arranged on the fixed base and a three-way acceleration sensor body arranged on the fixed base. A control circuit is arranged in the control chip, the signal output end of the three-way acceleration sensor is connected with the control circuit, and an alarm indicator lamp connected with the control circuit is arranged on the front end face of the box body. The accuracy of the vibration testis improved and the hardware cost is reduced by the device. The device also has the characteristics of small size, convenience in carrying, low manufacturing cost, convenience in installation, high precision and the like and meets the all-weather real-time monitoring of the vehicle and effectively reduces the safety operation risk of the vehicle.
Description
technical field [0001] The invention relates to the field of rail transit detection, in particular to a vehicle stability detection device for a rapid train set. Background technique [0002] As the running speed of EMU increases and the span of the line increases, the stability of the vehicle is particularly important. During the operation of the vehicle, if there is vehicle vibration caused by changes in line conditions, wheel set polygons, and equivalent taper, it may lead to problems such as cracks in the frame, cracks in the axle box, falling off of running parts, and serious impact on the track. The internal structure is damaged, and even the risk of derailment is caused, which brings a serious test to the safe operation of the vehicle. Using suitable portable equipment to monitor vehicle stability is an important means of monitoring vehicle operation status. At present, the main method of vehicle stability monitoring is tracking test, which can timely and accurately...
