摘要: 应用ABAQUS有限元分析软件, 结合热-力耦合理论和传热学理论, 模拟了在紧急制动下制动盘的温度场和热应力场分布, 并研究了制动盘结构参数对温度场和应力场的影响.以现有厚度的制动盘为研究对象, 运用单因子变量法, 研究了制动盘厚度为9, 11, 12和13mm时对温度和应力的影响以及两种不同结构的通风孔对温度和应力的影响.结果表明:当厚度为13mm时, 制动盘的最高温度降低了15.25%, 最大应力降低了19.29%, 与实心式结构的制动盘相比, 夹层式结构通风孔的制动盘可使最高温度降低8.06%, 最大应力降低30.67%, 增大制动盘厚度可减小最高温度和最大应力;孔板式结构通风孔的制动盘表面温度较夹层式低, 但应力较大, 故夹层式结构通风孔的制动盘较孔板式结构通风孔的制动盘总体性能更优.

Abstract: This article simulates car brake disc distribution of temperature field and stress field, and discusses how brake disc structural parameters influence temperature field and stress field by ABAQUS and combining thermal-mechanical coupling theory and heat transfer theory when take emergency braking.Based on an existing brake disc, the thickness of the brake disc is researched by applying the method of single factor variable for 9 mm, 11 mm, 12 mm and 13 mm on the influence of temperature and stress, with researching the structure of the vent.As the result shows, when the thickness is 13 mm, the maximum temperature reduces 15.25% and the maximum stress reduces 19.29%.A sandwich type vent brake disc can make the maximum temperature reduce 8.06% and the maximum stress reduce 30.67%, comparing with the solid.Increasing the thickness of the brake disc can reduce the maximum temperature and the maximum stress.The temperature of the plate-hole type vent is lower but with high stress.On the whole, compared with the plate-hole type vent, the sandwich type vent performances better.
