摘要：
Aiming at the problem of low prediction temperature caused by only considering the elastic modulus of elastic rubber outside the contact wheel in the existing temperature calculation model, a method for predicting the robotic belt grinding temperature at the blade edges under the influence of contact wheel-blade contact elastic deformation was proposed. Firstly, the combined elastic modulus of the aluminum alloy core and external elastic rubber was calculated according to the elastic modulus formula. Secondly, both the contact area and material removal depth when considering the combined elastic modulus of the contact wheel were calculated based on the Hertzian elastic contact theory. Thirdly, the energy partition during the grinding process was determined to obtain the heat flux transferred into the blade edges. The ANSYS software was used to simulate the temperature distribution at the blade edges when considering the combined elastic modulus of the contact wheel and only considering the elastic modulus of the elastic rubber under different parameters, and the results were compared with the experimental values. The results show that the average relative error between the simulated temperature and experimental values considering the combined elastic modulus of the contact wheel is 13.9%, which verifies the rationality of the proposed method. This method also can provide an optimized strategy for the local burn control of blade edges in the future work. © 2022, Editorial Board of Journal of Huazhong University of Science and Technology.
