【摘要】 制动夹钳作为制动系统的执行机构，是保证列车安全行驶的重要部件。目前市场上缺乏针对轨道梁制动悬挂式单轨列车的制动夹钳试验台，为验证制动夹钳的安全性和可靠性，文章设计了一种用于测试和评估制动系统性能的试验台，包括模拟工况装置、制动夹钳调整机构等多个独立模块，并建立试验台及制动夹钳的三维模型，最后利用有限元分析软件，对制动夹钳、模拟工况装置中的链轮驱动轴在工作状态下的受力进行仿真分析，计算各部件的变形和等效应力等。仿真结果表明，制动夹钳变形量以及最大等效应力在Q345钢的屈服强度和弹性形变范围内，驱动轴的总变形量和最大等效应力在45钢的屈服强度和弹性形变范围内，满足设计需求，同时也为后续的结构优化提供了方向和依据。更多还原

【Abstract】 Brake calipers serve as the actuators in braking systems and are critical components for ensuring the safe operation of trains. However, there is currently a lack of dedicated test benches for brake calipers used on suspended monorail trains that employ a track beam braking system. To verify the safety and reliability of these brake calipers, this paper presents the design of a test bench for testing and evaluating braking system performance. The bench comprises several independent modules, including a condition simulation mechanism and a brake caliper adjustment mechanism. Based on the structural design, 3D models were established for both the test bench and the brake calipers. Subsequently, simulation analyses were performed using finite element analysis software to calculate the deformation and equivalent stress of various components subjected to loading under working conditions, specifically focusing on the brake calipers and the sprocket drive shaft within the condition simulation mechanism. The simulation results indicate that both the deformation and maximum equivalent stress of the brake calipers fall within the yield strength and elastic deformation limits of Q345 steel.Similarly, the total deformation and maximum equivalent stress of the drive shaft are within the yield strength and elastic deformation limits of 45 steel. These findings align with the design requirements and provide guidance and a basis for subsequent structural optimization.更多还原
