EFFECTS OF ADDING BRACKET JOINT ON RIGIDITY AND STRENGTH OF SPATIAL 3-ROD STRUCTURE OF BUS BODY
Published 2015-01-01“…Spatial 3-rod structure is one of the bus basic structures.Effects of the topological locations of angle brackets on the rigidity and strength of spatial 3-rod structure of bus body were discussed.The calculation by finite element calculation and experimental analysis showed that:1The structural rigidity and strength under bending loads were enhanced remarkably when the plane of angle bracket was parallel to the bending loads direction.2The structural rigidity and strength under torsion loads were enhanced remarkably when angle bracket was added at the top side of the joint between the load-carrying rod and side rod.3The most effective way to enhance the structural rigidity and strength and improve its high stress distribution was adding one angle bracket at the top side of the joint between the load-carrying rod and side rod and another angle bracket at the lateral side of the joint between the load-carrying rod and master rod( the tenth angle bracket location).This paper provided a valuable reference to the design of agricultural machinery and engineering structures,besides the bus body joints design.…”

Published 2024-08-01“…In order to achieve high⁃precision and pure⁃center rotation motion in micro/nanomanipulation tasks,a monolithic pure⁃center rotation platform was designed using two⁃stage compliant amplification mechanisms and a single piezoelectric actuator.Compared with other platforms,the designed rotation platform exhibited the merits of no actuator redundancy,high natural frequency,large rotation angle,and compact structure.The static and dynamic models were established by combining the pseudo⁃rigid body and finite element methods.Also,the output angle,input stiffness,output stiffness,and natural frequency of the rotation platform were simulated by Ansys software.Finally,an experimental test system was built,and the performance of the platform was tested through several experiments.Also,the feedforward control was used to compensate for the piezoelectric hysteresis.The experimental results show that the rotation angle is 16.8 mrad,the natural frequency is 527.3 Hz,and the resolution is 0.3μrad.Meanwhile,the hysteresis nonlinearity is compensated effectively using feedforward control.Thus,the platform is capable the high precision center rotation operation.…”
