| 摘 要： | 作为汽车制动系统中的关键部件,制动鼓的机械性能备受关注。为了提高制动鼓的强度与散热能力,分析了加强筋结构与制动鼓性能间的关系。在ANSYS平台上进行了制动鼓的强度评估;联合STAR-CCM+与ANSYS软件,利用热结构耦合分析衡量了制动鼓的强度与散热的综合性能。结果表明:菱形筋制动鼓虽然在强度上好于螺旋筋制动鼓,但是由于散热能力较差,使得螺旋筋制动鼓综合性能更优。

| Abstract: | As a key component in Automobile Brake System, the mechanical properties of brake drums always arouse more attention. In order to improve the performances of strength and heat dissipation, relations between rib structure and the brake drum perfnrmances were analyzed. The strengths of brake drums were evaluated on the platform in ANSYS. The comprehensive performances of strengths and heat dissipation of brake drums were assessed through the thermal-structural coupling analysis based on the co-simulation in STAR-CCM＋ and ANSYS. The results indicate that although rhombus rib brake drum performs better in strength evaluation, the spiral rib brake drum has better combination properties than rhombus rib brake drum because of the worse heat dissipation of rhombus rib brake drum. |
