It is necessary to carry out various movements to understand the functions of agricultural machines. These movements are usually taken from the tractor shaft, the hydraulic control system or the wheel. Various mechanisms are used to ensure movement and to make agricultural machinery work. With these mechanisms, the direction and the number of movements can be changed. One of these mechanisms is crank-rod mechanisms and these mechanisms turn various actions into a complex movement. Consequently, the crank-rod mechanism of the tractor motor can be analyzed with limb mechanisms. In this study, the crank-rod mechanism of a tractor motor was dimensioned in different lengths and subjected to the kinematic analysis of MSC ADAMS software. The kinematic analysis of a single crank-rod mechanism for the engine gives important information about the tractor engine. Kinematic evaluation parameters of these mechanisms can be listed as displacement, velocity, and acceleration. These values related to the crank-rod mechanism of the tractor engine are evaluated and presented in the results and discussion section of the research for a better understanding of the kinematic characteristics of the crankrod motion.

“…On the other hand, although the mathematical model could be solved within a short time, the accuracy of the model affects the reliability of the results. Researchers have proposed various methods, where the compliance matrix method [109][110][111] and pseudo-rigid-body model (PRBM) [112][113][114][115][116] are two of the most-used methods for modeling the flexure hinges. With years of practice, the reliability of both of these has been well verified.…”

Micromanipulation is a hot topic due to its enabling role in various research fields. In order to perform a high precision operation at a small scale, compliant mechanisms have been proposed and applied for decades. In microscale manipulation, micro-/nano-positioning is the most fundamental operation because a precision positioning is the premise of subsequent operations. This paper is concentrated on reviewing the state-of-the-art research on complaint micro-/nano-positioning stage design in recent years. It involves the major processes and components for designing a compliant positioning stage, e.g., actuator selection, stroke amplifier design, connecting scheme of the multi-DOF stage and structure optimization. The review provides a reference to design a compliant micro-/nano-positioning stage for pertinent applications.

Abstract. This paper presents a geometric synthesis method for compliant mechanisms based on similarity transformation of pole maps. Motion generation is a typical and common mechanism synthesis task, so this study takes it as the design requirement to expound the proposed method. Most of the current research work relies on numerical solution of the nonlinear Bernoulli–Euler beam model, numerical simulations or physical experiments to study the synthesis method of compliant mechanisms. There is a lack of simpler and more efficient methods to achieve motion generation of compliant mechanisms with various topologies. This study is based on pole map which is a geometric tool to describe the motion of rigid-body mechanisms. In this paper, we first demonstrate the feasibility of applying the similarity transformation of pole map to compliant mechanisms. It is proved that the pole map of compliant mechanisms has the same characteristic as rigid-body mechanisms during similarity transformation. Then we present the procedure of synthesis method in detail and expound the establishment method of function module which can avoid the functional defects of the final designed mechanism. At last, we take the compliant geared linkages and compliant four-bar linkage as examples to illustrate the novel synthesis approach. The result is an applicable and effective synthesis method for motion generation of compliant mechanisms.
