Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a single-axis acceleration sensor device and a preparation method for detecting acceleration signals of a bogie of an EMU. Background technique [0002] The EMU bogie is a device that supports the car body and carries the car body running on the track. It bears the weight of the upper part of the EMU, including the weight of the car body and various instruments and electrical equipment installed in the car body. The spring suspension is transferred to the rails. The bogie transmits gravity, traction force, braking force during the operation of the EMU, and also transmits lateral force when passing through a curve. [0003] Among them, the EMU needs to be based on the acceleration achieved by the EMU bogie during its operation, so installing an acceleration sensor on the EMU bogie can feed back the real-time acceleration signal of the EMU during its operation in real time. [00...
