Design and stress analysis of wheeled compactor construction

Abstract

The article deals with the design of compactor for a backhoe loader for middle size excavators. Construction of compactor clamp was designed from heavy gauge sheets which will be welded. For expansion of penetrating into thickening soil there were segments designed on drum. From the point of fatigue during comparison of reached maximal tensions and comparison of these values for several loaded alternatives from Wöhler curve was defined static safety factor.

Kinematics Analyses of the Spatial Mechanism Using Matlab

“…The objective of computational methods in kinematics and dynamics is to create a formulation and digital computer software that allow the engineer to input data that define mechanical systems of interest and automatically formulate governing equations of kinematics, automatically solve non-linear equations for kinematic response, and provide computer graphics output of results of simulations to communicate results to the designer or analyst.The essence of this objective is to make maximum use of digital computer power for rapid and accurate data manipulation and numerical computation, hence relieving the engineer of tedious and error-prone calculations [1,2]. As suggested by advances in computer-aided finite element structural and electronic circuit analysis, a systematic approach to the formulation and solution of the equations of kinematics and dynamics of mechanical systems is required to implement computations in a user-oriented computer program [3][4][5][6]. Several computer programs for kinematic and dynamic analysis were developed in the late 1960s and early 1970s [7][8][9] using relative coordinates between bodies.…”
