Could you provide a picture about how the IMU (in the simulation) is installed on the metro when you apply the pitch = 180deg flip?
To me, usually ZYX sequence is used in the simulation by default. The range for the pitch angle should be [-90, 90]deg. Besides, even if pitch = 180, the X acceleration should still point along the motion direction of the metro. Without velocity amplitude change, X acceleration should be always zero while the Y acceleration should show acceleration due to rotation.
