“…As shown in Figure 6 , based on the kinematic analysis of the root-cutting mechanism, constraints, forces, drives, and dummy objects were added to build a rigid-flexible coupling model of the root-cutting mechanism and garlic plant in ADAMS ( Yu et al., 2023 ). The stationary components were fixed to the reference system, while the revolute and translational pairs were used to define the constraints between components with rotational and linear relative motion relationships ( Prastiyo and Fiebig, 2021 ). Simultaneously, dummy objects were constructed to assist the addition of motion constraints between the flexible body model of the garlic plant and interacting components.…”

IntroductionRoot cutting is an important process in garlic field harvesting but is the weakest link in the full mechanization of garlic production. To improve the current situation of technological backwardness and poor operational quality of mechanized garlic root-cutting in the main garlic-producing regions of China, this study combined the physical characteristics and agronomic requirements of garlic plants, and proposed an innovative floating root-cutting technology for garlic combine harvesters that enables the top alignment of bulb, adaptive profiling floating of cutter, and embedded cutting of roots.MethodsThrough the kinematic analysis of the floating cutting process, the coordinate equations of the initial contact point of the bulb, the mathematical model of the floating displacement of the cutting component. Using computer simulation techniques, the dynamic simulation study of the floating cutting process was carried out in the rigid-flexible coupling numerical simulation model of root-cutting mechanism and garlic plant. The influence law of garlic conveying speed, extension spring preload force and stiffness on the floating displacement of the cutting component and the angular velocity of swing arm reset and its formation causes were analyzed by a single-factor simulation test. The key operating parameters of the root-cutting mechanism were optimized through the computerized virtual orthogonal test and fuzzy comprehensive evaluation.Results and discussionThe significance of the factors affecting the floating cutting performance decreased in the following order: extension spring preload force, garlic conveying speed and extension spring stiffness. The optimal parameter combination of the root cutting mechanism obtained from the optimization were as follow: extension spring preload force was 16 N, garlic conveying speed was 0.8 m/s, and extension spring stiffness was 215 N/m. Tests conducted with the optimal parameter combination yielded a root excision rate of 92.72%, which meets the requirements of Chinese garlic field harvesting quality. This study provides computer simulation optimization methods for the optimal design of the root-cutting mechanism, and also provides technical and equipment support for the full mechanization of garlic production in China.

The identification and sensitivity analysis of compound vibration is the basis of vibration control of vehicle body. In the paper, the mechanism and key influencing factors of compound vibration are analyzed by establishing the dynamic mathematical model with 11 degrees of freedom, and the experiment method for identifying compound vibration is put forward. The sensitivity of influencing factors of compound vibration of the body is analyzed by establishing a rigidflexible coupling dynamic simulation model. The results show that vertical vibration, roll vibration and pitch vibration are the main forms of the vehicle body vibration, the key influencing factor of vertical vibration is rear suspension stiffness, the key influencing factors of roll vibration are lower control arm length and rear suspension damping, front suspension stiffness and rear suspension stiffness are the key influencing factors of pitch vibration. The research results provide a theoretical basis and reference for mastering the composition and formation mechanism of compound vibration of vehicle body.

“…Further kinematic analysis is performed and through results, it has been concluded that it is a major advantage for overall improvement in automobile stability. [3] The following paper presents a comparative study of linear and progressive spring rates used in double wishbone suspension, thus concluding the ideal spring structure to be used in lower-class rally cars. According to rally cars, the servicing period at the service park is limited and suspensions like air suspension or hydro-pneumatic in a double-wishbone suspension setup are risky, as they are not cheap and can consume a lot of time.…”

Double Wishbone suspension systems are by far the best choice of suspension systems recommended for sports vehicles. It is more stable and stiffer when compared to the other suspension geometries. In this report a brief study of how a double-wishbone suspension system acts under loading conditions when traveling at high speeds is presented, also the forces acting on its components are analysed, and post-processed results are discussed. The geometry of the whole suspension is designed on SolidWorks and analysis is performed on Ansys software. Further the results from the analysis are studied based on material selection and various analysis methods. Finally, the proposed suspension system is concluded safe to use when the values of Equivalent stress, Total Deformation, and Factor of Safety were measured and under threshold limits. Keywords: double wishbone suspension, static structural, suspension system, analysis, deformation, Ansys, stress analysis, FOS, FEA, structural analysis.
