Embodiment Construction

[0026] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] The clutch friction pair is one of the important basic components of the transmission system. In actual engineering, pitting, cracks and even fractures often occur on the meshing teeth during power transmission of the friction pair. In order to explore the reasons for the above-mentioned damages in the meshing transmission of the friction pair teeth, it is necessary to study the circumferential load distribution characteristics and changing rules of the friction pair tooth strength in the meshing transmission process. To obtain the above characteristic parameters, corresponding experimental tests must be carried out.

[0028] According to the limit value required by the transmission device for the power transmis...

Abstract

The invention belongs to the technical field of testing simulation, and provides a method for obtaining circumferential load distribution of a friction plate tooth part through variable-contact-rigidity testing. The method aims at carrying out testing on static stress on the friction element tooth part, accordingly achieving mutual verification of two distribution rule testing results, and providing theoretical supports for dynamic strength simulation and design of a friction element. According to the method, the mass data synchronous collecting problem difficult to solve can be solved, middle testing links and a data processing link are omitted, the distribution characteristics of circumferential loads of the friction plate tooth part can be directly obtained through a variable-contact-rigidity curve obtained through the testing, and the accuracy of the testing results is improved; the testing method is simple, practical and high in testing result accuracy.

Description

technical field [0001] The invention belongs to the technical field of test simulation, and in particular relates to a method for obtaining the circumferential load distribution of a tooth part of a friction plate through a variable contact stiffness test. Background technique [0002] As an important part of special vehicles, the transmission system's performance directly affects the mobility (such as braking, passability, acceleration), reliability and service life of the vehicle. The failure of the transmission system will directly lead to the loss of use of special vehicles. [0003] The clutch friction pair is one of the important basic components of the transmission system. In actual engineering, during the power transmission of the friction pair, damages such as pitting, cracks and even fractures often occur on the meshing teeth. The distribution characteristics of the circumferential load and its variation law. To obtain the above characteristic parameters, the cir...
