Abstract ：
The current traditional method of plant layout is still relied upon in design and does not take into account factors such as facilities and equipment, personnel and materials. In order that the problem of interaction and integration between the virtual and physical worlds in the plant design process can be solved, this paper proposes a layout and simulation technique based on the SLP method to carry out the analysis of the digital design of a tomato plant plant as an example First, the tomato digital factory is studied, and the layout scheme is obtained by combining the SLP design method in a comprehensive way. Then, the digital modeling of parametric modular one-to-one correspondence is performed to integrate the digital twin model. Finally, the feasibility of the design scheme is verified by using PlantSimulation modeling simulation, which provides a new design idea for the digital design of intelligent factory.

Abstract ：
To solve the problem of poor systematization and ambiguous input of agricultural machinery in requirement analysis, using MBSE theory combined with the development and design of key mechanisms for automated cuttings equipment, an improved method of requirement analysis for automated cuttings equipment is proposed. By refining participant requirements, a natural language description of the set of user requirements is generated. An itemized set of requirements with standard information is constructed by the proposed semantic model for the standardization of requirements. At the same time, the requirements are verified based on the activity diagram in SysML using a logic simulation method to update the entry set of requirements. On this basis, the requirement model of the key mechanism of the automated cuttings equipment is created by SysML, and the input of the mechanical design information data flow is realized. The results show that the method improves the development process from initial requirements to requirement models, ensures consistency and traceability between the two, and can provide a design basis for the development of automated cuttings equipment.

Abstract ：
This article mainly analyzes the free vibration characteristic of the sandwich piezoelectric beam under elastic boundary conditions and thermal environment. According to the first-order shear deformation theory and Hamilton's principle, the thermo-electro-elastic coupling equations of the sandwich piezoelectric beam are obtained. Meanwhile, elastic boundary conditions composed of an array of springs are introduced, and the displacement variables and external potential energy of the beam are expressed as wave functions. By using the method of reverberation-ray matrix to integrate and solve the governing equations, a search algorithm based on golden-section search is introduced to calculate the required frequency parameters. A series of numerical results are compared with those reported in literature studies and obtained by simulation software to verify the correctness and versatility of the search algorithm. In addition, three parametric research cases are proposed to investigate the frequency parameters of sandwich piezoelectric beams with elastic restraint conditions, material parameters, thickness ratio, different temperature rises, and external electric potential.

Abstract ：
A novel compliance modeling method for flexure-hinge-based (FHB) compliant parallel mechanisms is proposed, where internal constraint of branches is taken into consideration based on flexibility-center-decomposition method of compliance matrix and screw theory. The modeling method is employed to transform deformation problem of branches into statics and kinematics problems of pseudo-rigid-body branches. Firstly, the virtual branch is established and its corresponding decoupled compliance matrix is obtained. Then, the compliance modeling of the whole mechanism is obtained by static equilibrium equation and kinematic relations. Secondly, a constraint performance index reflecting ability to constrain undesirable deformation of the compliant parallel mechanism is presented based on the decoupled compliance matrix. The effectiveness of the constraint performance index is verified through analysis of degree of freedom (DoF) of the 3-SS mechanism. Finally, the proposed modeling method and performance index are used in design and analysis of a novel RPR compliant parallel mechanism. To our knowledge, constraint performance index is firstly proposed for assessing the ability to constrain undesirable deformation of the compliant parallel mechanism. (c) 2021 Elsevier Ltd.

Abstract ：
Purpose The purpose of this paper is to present a follow-the-leader motion strategy for multi-section continuum robots, which aims to make the robot have the motion ability in a confined environment and avoid a collision. Design/methodology/approach First, the mechanical design of a multi-section continuum robot is introduced and the forward kinematic model is built. After that, the follow-the-leader motion strategy is proposed and the differential evolution (DE) algorithm for calculating optimal posture parameters is presented. Then simulations and experiments are carried out on a series of predefined paths to analyze the performance of the follow-the-leader motion. Findings The follow-the-leader motion can be well performed on the continuum robots this study proposes in this research. The experimental results show that the deviation from the path is less than 9.7% and the tip error is no more than 15.6%. Research limitations/implications Currently, the follow-the-leader motion is affected by the following factors such as gravity and continuum robot design. Furthermore, the position error is not compensated under open-loop control. In future work, this paper will improve the accuracy of the robot and introduce a closed-loop control strategy to improve the motion accuracy. Originality/value The main contribution of this paper is to present an algorithm to generate follow-the-leader motion of the continuum robot based on DE. This method is suitable for solving new arrangements in the process of following a nonlinear path. Then, it is expected to promote the engineering application of the continuum robot.

Abstract ：
This paper presents a new vaporizing liquid microthruster (VLM), which is driven by the vaporizing liquid with planar induction heating. The developed microthruster mainly consists of an inlet, a microchannel, a vaporizing chamber, a micronozzle, a microheating plate and an external excitation coil. Experiments of the apparent power required to achieve a complete vaporization of the propellant with different flow rates were carried out. Thrust forces of the new VLM were characterized with water as the propellant. A maximum thrust of 970 mu N was obtained with 5.30 mg/s propellant consumption and an apparent power of 9.31 VA.
