本文旨在确定接触几何形状对轮内制动系统中温度分布和热屈曲的影响。通过数值分析研究了在保持相同摩擦力矩的情况下,不同制动片覆盖角度下制动盘上温度场分布的变化。此外,还考虑了盘上垫的不同位置。为了验证模拟结果,导出了解析解。结果表明,对于盘上的垫所做的相同功,所产生的温度场分布对盘具有不同的影响。此外,某些接触几何形状被发现会导致制动温度超过临界温度,从而导致制动盘在制动过程中发生热屈曲。
This paper aims to determine the effect of contact geometry on temperature distribution and thermal buckling in an in-wheel brake system. Numerical analysis is conducted to investigate the variation of temperature field distribution on the brake disc a different cover angles of the pad while maintaining the same moment of friction. Also, different positions of the pads on the disc are considered. To verify the simulation results, an analytical solution is derived. The results show that, for the same work done by the pads on the disc, the resulting temperature field distributions have various effects on the disc. Moreover, certain contact geometry was found to cause the braking temperature to exceed the critical temperature, leading to thermal buckling of the disc during braking.
