Embodiment Construction

[0078] like Figure 1 to Figure 5 As shown, a DOE-based and MBD-based mitigation performance optimization method for the braking device includes the following steps:

[0079] S1. Determination of controllable factors in performance optimization DOE test:

[0080] The diameter of the pin shaft, the thickness of the floating lever, the width of the splint of the middle tie rod, and the width of the brake beam column groove are the controllable factors of the DOE test; in step S1, the specific steps for determining the controllable factors of the performance optimization DOE test are as follows:

[0081] S11. The combined results of the gaps at the joints of the brake device have a great influence on the relief performance. Therefore, the size of each brake joint is a factor that affects the relief performance.

[0082] S12. The force of the connecting pin reflects whether there is a sticking and its severity in the mechanism. The size of the pin with abnormal force is the key f...

It takes the minimum release force as the test index to obtain the best clearance configuration scheme for hinges and rods, so as to optimize the release performance of the foundation brake device. the goal of.

Description

technical field [0001] The invention relates to the field of truck braking, in particular to a DOE and MBD-based mitigation performance optimization method for a foundation braking device. Background technique [0002] The bogie foundation brake device is the executive mechanism for the train to decelerate and stop, and is an essential device to ensure the safe operation of the vehicle. [0003] With the increase of vehicle load and traction tonnage, there are higher requirements for the performance of the basic braking device. It is required to be stable and reliable when braking, and to be safe and efficient when relieving; the reliability of the braking system directly affects the performance of the braking system. Safety of train operation. [0004] Therefore, it is particularly necessary to analyze the performance of the basic braking device. The measures to improve the performance of the braking device are to adopt new braking technology, and to improve and optimize t...
