AI Technical Summary
The existing heavy-duty truck brake damper has a uniform perforation design that causes heat to accumulate and form local hot spots. This leads to material aging and periodic thermomechanical stress at the joints, resulting in weld cracking and warping deformation, which threatens the stability of the braking system.
By acquiring the structural, working condition, and material property parameters of the brake baffle, a temperature field distribution is generated using a thermal simulation model. The structural parameters are then adjusted based on the thermomechanical stress distribution to optimize the opening layout, stiffener design, and local thickness, thereby mitigating the failure problem caused by thermo-mechanical coupling.
It significantly improves the brake damper's resistance to thermal fatigue and structural stability, ensuring that it continues to perform its protective and support functions under high temperature and high frequency vibration conditions, and guaranteeing the safe and stable operation of the braking system.
