“…Such examples can be seen in Table 3, which contains the simulation results. Similar results on how the current affects the MF in the damper can be observed in the studies conducted by Purandare et al [22], T. M. Gurubasavaraju et al [27], and Guoliang Hu et al [31]. It has also been found that as the number of turns on the coil and the current increase, so do the MF and DF (Figures 12 and 13).…”

Magnetorheological dampers (MRDs) are devices that adjust their damping properties in response to an external magnetic field. Large-scale MRDs have been successfully used as vibration control devices in structures. This study focuses on modelling and optimizing an MRD using COMSOL Multiphysics. Various parameters, such as coil turns and current, are optimized to achieve the maximum flux value in the MRD. The simulation yielded a maximum magnetic flux of 0,44 T with 500 coil turns. Based on the optimized MRD parameters, a numerical equation is then used to calculate the total damping force. The maximum numerical and experimental damping forces corresponding to a 2,0 A current were 989,39 and 1004,63 N, respectively. The numerical damping force is then compared to the experimental results to validate the accuracy of the model. The MRD is integrated into a scaled-down reinforced concrete frame and subjected to a cyclic loading test for performance evaluation. The results show that the MR dampers improve the performance of the frame structure, increasing its load-carrying capacity and energy dissipation by 19,45 % and 20,43 %, respectively. The findings of the study provide valuable insights into the behaviour of MRDs and their optimization using numerical simulations, as well as highlight the importance of experimental validation for accurate prediction of the performance of MRDs in practical civil engineering applications.

“…According to the modelling results, the temperature of the MRF increased but did not exceed operating limits. Hu et al [31] created a volume-limited geometrically optimized MR valve. They combined the Taguchi orthogonal experiment and response surface methodology with a COMSOL FE model (FEM) for the optimization process.…”

“…There are also researchers who have designed and optimized a new MR damper based on B-spline curve and designed and produced a damper that is better in all aspects than the prototype from previous work (Liu et al, 2021b). Additional researchers used Taguchi’s orthogonal experimental method to optimize the structure of the magnetorheological valve and determine the optimal geometry of the magnetorheological valve to maximize the valve performance (Hu et al, 2022). In order to solve the problem of conflicting output damping force and damping adjustable coefficient after the magnetorheological damper is subjected to impact load in the launcher, a new three-channel magnetorheological damper structure is proposed, and the study shows that it can make full use of the multi-channel and multi-coil structure of the magnetorheological damper and improve the damping performance of the magnetorheological damper (Zhu and Zhang, 2022).…”

In order to meet the damper performance requirements of heavy vehicles, a stepped-bypass magnetorheological damper is proposed. The mathematical model of damping force is deduced, and its mechanical properties are numerically simulated. Then the damper is manufactured, and the mechanical properties of the stepped bypass magnetorheological damper are experimentally studied. The simulation are consistent with the experimental results. The damper is optimized by orthogonal optimization design test. Finally, it is concluded that the maximum output damping force of the stepped bypass magnetorheological damper is about 4500 N, and the adjustable coefficient K is about 5.4. After optimization, the damping force of the stepped bypass magnetorheological damper is increased by at least 5.3%, and the adjustable coefficient K is at least 1.37 times that before optimization, which is 13% wider than that before optimization.

“…A design scheme is proposed after comparing 18 optimization schemes that effectively improve the subjective design flaws of the constructors during building design and increase energy saving, cost-benefit ratio, and carbon emission reduction considerations. Hu et al (2022b) proposed a method in response to the problems of increasing form factor and deterioration of key performance indexes by structural optimization methods used in the design process of magnetorheological (MR) valves. A geometric optimization design method is proposed for the optimal design of MR valve structures under specific volume constraints.…”

With the rapid technological progress of society and increasingly stringent environmental regulations, further reduction of emissions has become an important issue for environmental protection. This study developed a response surface model with the biodiesel blending ratio (BBR), load, and exhaust gas recirculation (EGR) as independent variables and brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), and NOx, and CO emission rates as dependent variables. Simulations were performed and calculated. The results of the response surface approach with the objectives of maximizing the BTE of the engine and minimizing BSFC, NOx emissions, and CO emissions show that when the BBR is 20%, the EGR rate is 15%, and the engine load is 74.52%, pollutant emissions are significantly reduced while the engine power’s performance is maximized.
