“…Generally, the more joints consisted in the pseudo-rigid-body model, the higher the prediction accuracy. Feng et al 24,25 proposed a 2R pseudo-rigid-body model and the average errors of member tip locus are less than 0.12% under specific deformation conditions. Chen et al 26 found the optimal characteristic parameter for 3R pseudo-rigid-body model by using an improved particle swarm optimizer, and the tip slope error is 0.12%.…”

A lapping loading device that makes use of a compliant mechanism for a novel ring-type tapered roller lapping method is proposed in this paper. A three-part guide post structure is designed using the new type of tapered roller processing principle. For the purpose of designing and analyzing of the three-part guide post structure, a pseudo-rigid-body model for the mechanism of the three-part guide post is developed. Based on the pseudo-rigid-body model, the loading mechanisms and the mechanical behavior of the three-part guide post structure were discussed in this work simultaneously. The computation model of the lapping force in the machining of the tapered roller lapping was developed and validated through the finite element method and experiment results. This shows that the developed computation model possess high enough accuracy to effectively control the lapping loading force. This research established the viability of using the compliant mechanism in the field of the tapered roller processing technique.

“…The arc leg is a compliant mechanism, and it is hard to analyze the buffering performance because the arc leg introduces geometric nonlinearities. The pseudo-rigid-body model used in this study can simplify large-deflection analysis [34][35][36]. For the first walking way (the midpoint of the arc leg lands first), the leg structure which plays a role in buffering can be considered to be 1/4 circles.…”

A wheel-legged rescue robot design with strong environmental adaptability is proposed. The design presented is aimed at helping rescue workers complete their missions, such as environmental and personnel search, quickly and accurately. So it has broad application prospects. In order to achieve the advantages of simple structure, easy control, small occupation space, and wide motion range, a wheel-legged rescue robot is designed in this paper, and the robot can realize three kinds of motion states, which include wheel state, rotation center lifting process, and leg state. Then the motion states are analyzed in detail, which provides a reference for motion control. Considering the wheel state and leg state share the same structure to contact with the ground, the effect of the stiffness of wheel-legged structure to the motion performance is analyzed. Then the experiment is carried out to prove the feasibility of the structure design. This study offers a design and quantitative analysis for wheel-legged rescue robot. Furthermore, a basis for future control research and engineering applications is established.
