Abstract ：
Temperature is an important factor affecting the performance of magnetorheological brake. In order to improve the heat dissipation performance of magnetorheological brake, annular cooling fins are designed based on TRIZ theory, and its temperature field simulation mathematical model is established. The effects of cooling fins on the magnetic field distribution and heat transfer of the brake are investigated by the coupled finite element method. An experimental platform was designed and constructed to verified the actual performance of the heat dissipation system is verified. The results show that after installing the cooling fins, the maximum temperature of the brake is reduced by 1.09 % after 30 min of static energization, and the maximum temperature is reduced by 4.40 % after 30 min of heat dissipation. The maximum temperature of the brake is significantly reduced after installing the cooling fins in the single and continuous braking conditions. Under the initial braking speeds of 20 km/h, 40 km/h, 60 km/h and 80 km/h, the maximum number of consecutive braking times of the brake is increased by 31.19 %, 14.81 %, 12.50 % and 16.67 %. After installing the cooling fins, the torque decay rate of the brake was reduced by 5.54 % after 5 min of continuous torque output.

Abstract ：
In order to apply bionics and innovation methods to product innovation design in distributed resource environment, a method of product bionic innovative design based on EQA (Extractive question answering) and AD (Axiomatic design) is proposed. Firstly, the biological text and engineering design information database by text mining are constructed to realize the processing and storage of biological and engineering data. Secondly, to match the appropriate biological parameters from the perspective of design function, an EQA-based question and answering system is constructed as well as a biological parameter acquisition method was proposed. Then, based on the product bionic innovative design process integrated with EQA and AD, the transformation from user requirements to design schemes is realized and the feasible product design schemes are obtained. Finally, the corresponding bionic design assisted software system is developed to assist the designer to carry out innovative product design, and the design of ultraviolet disinfection vehicle is taken as an example to further demonstrate the feasibility and effectiveness of the proposed product bionic innovative design method. © 2024 Chinese Mechanical Engineering Society.

Abstract ：
Accurate engineering modeling of flour is often required for the calibration of its contact parameters in flour conveying systems. In this study, a typical calibration of contact model parameters was proposed to consider the effects of cohesion between flour particles and particle size, according to the static and dynamic angle of repose. Hertz-Mindlin with Johnson-Kendall-Roberts (JKR) contact model was also selected using the particle scaling theory. The orthogonal simulation tests were carried out to implement the sensitivity and variance analysis of the contact parameters using the discrete element method (DEM) model. The result showed that there were the most significant effects of JKR surface energy, the powder-powder coefficient of rolling friction, and the powder-steel coefficient of static friction on the static angle of repose. Since the contact parameters were calibrated only by static angle of repose, the cross-effects of multiple parameters were verified as well. Different combinations of contact parameters produced a similar effect of static angle of repose. Furthermore, five sets of contact parameters were selected to obtain a unique set of parameter values as the candidates. Their simulation from the static angle of repose was the closest related to the test. Then the dynamic stacking was further studied. The flour was filled in a cylindrical container with a transparent bottom and stainless-steel side. In the tests, the cylindrical container was set as 100 mm in diameter and 30 mm in height and then rotated around the axis at the given speed. The camera was used to record the dynamic angle of repose, which was defined as the maximum tilt angle between the slope and the horizontal plane before the powder collapsed. The contact parameters calibrated by the dynamic angle of repose were also verified under the condition of a single filling rate and a single rotational speed. Therefore, the dynamic angle of repose was further calibrated at the filling rates of 0.2 and 0.4, respectively, while the rotational speeds of 30, 40, 50, and 60 r/min. Optimal contact parameters were achieved for the flour with a powder-powder coefficient of restitution of 0.6, a powder-powder coefficient of static friction of 0.2, a powder-powder coefficient of rolling friction of 0.1, a powder-steel coefficient of restitution of 0.6, a powder-steel coefficient of static friction of 0.6, a powder-steel coefficient of rolling friction of 0.5 and a JKR surface energy of 0.12 J/m2. The dynamic angle of repose after DEM calibration was the closest to the test. The calibration with the dynamic angle of repose under various conditions effectively reduced the uncertainty of the calibration. After that, a rectangular container test was designed to verify the accuracy of the contact parameters. Among them, the flour was poured into a cube container with a side length of 100 mm, where the top surface of the assembly of flour was kept flat, and then the cabin lid of the container was lifted away, leading to the powder naturally flowing out of the container. The ratio of the flour mass remained to calculate the total mass in the container. There was a minimal relative error between the numerical simulation with the calibrated parameters and the measurement from the test. The DEM contact parameters of flour were improved in the reliability, simplicity, and feasibility of calibration. The finding can also provide a strong reference for the DEM parameters calibration of powdery materials in engineering applications. © 2024 Chinese Society of Agricultural Engineering.

Abstract ：
Creative thinking is the key factor of the product innovation design, and Bionic interaction design is a completely new method to achieve the creative design. In order to increase the abrasion resistance and reduce the natural frequency of automobile disc brake, and then weaken the brake squeal, the brake is designed from bionic points. Firstly, the brake is modeled at four levels of the function, principle, behavior and structure to fully express the internal relationship of the product; similarly, the corresponding biological system is modeled with function, strategy, action and structure based on the HIM. Meanwhile, considering the synergistic effect of multiple organisms, a multi-level Cooperative Mapping Mechanism based on multi-biological principle is raised to design the brake scheme. Secondly, thermodynamic and modal analysis of the bionic brake scheme is done. Finally, the bionic structure is parameterized designed based on numerical simulation to verify the feasibility and effectiveness of the proposed method. © 2020, Springer-Verlag France SAS, part of Springer Nature.
