目的
2
为了精确计算盘式制动器的制动盘制动力,建立了一种基于热源影响下制动片的准静态温度和热应力分布的制动盘制动力模型。
方法
2
首先,分析了单次制动过程中的能量转换机制;其次,基于制动过程中获得的准静态温度和热应力分布,通过数值方法构建了应力-制动力模型;最后,设计了仿真实例以验证模型的有效性。
结果
2
仿真结果表明,在制动中后期,受积温效应的影响,温度-制动力模型曲线略高于应力-制动力模型曲线;应力-制动力模型与温度-制动力模型曲线的趋势高度一致,最大差值为305 N,平均差值为2.371 5 N,平均相对误差为0.012 7%。该模型不仅为制动力的数值分析提供了依据,也为制动力检测开辟了新的思路和方法。
Objective
2
To precisely calculate the brake disc braking force of a disc brake system
a brake disc braking force model based on the quasi-static temperature and thermal stress distribution of the brake pad under the influence of heat source was established.
Methods
2
First
the energy conversion mechanism during a single braking process was analyzed. Then
based on the quasi-static temperature and thermal stress distribution obtained during the braking process
a stress-braking force model was constructed using numerical methods. Finally
a simulation example was designed to verify the validity of the model.
Results
2
The simulation results show that
in the later stages of braking
the temperature-braking force model curve is observed to be slightly higher than the stress-braking force model due to the influence of thermal accumulation effects. The stress-braking force model and the temperature-braking force model exhibit a high degree of consistency in their trends
with a maximum error of 305 N
an average error of 2.371 5 N
and the average relative error of only 0.012 7%. This model not only provides a basis for the numerical analysis of the braking force
but also provides new ideas and methods for the braking force detection.
