Abstract Stress concentration is the accumulation of stress in a body due to sudden change its geometry. Stresses and concentrations are created at nearer area structural discontinuities. Any discontinuity compromises strength structure. Numerical approaches can be used determine maximum for various complex geometries without regard time or cost constraints. The current study gives thorough finite element analysis steel plate with polygonal cutout. In contrast orientation area, this looks an...
The automation of the land excavation machines can find applications in soil both terrestrial and planetary mining construction.In process automating an earthmoving machine, we have utilized a model soil-tool interaction that predicts resistive forces experienced at tool during digging.The predicted be used to closed loop behavior controller serves joints excavator so as fill bucket.Accurately predicting force will encountered by digging tools on surface is crucial part designing mini...
An excavator is a typical hydraulic heavy-duty construction machine used in hazardous, worst working conditions, severe weather, and dirty areas where it very difficult to operate by human operator. The operations require coordinated movement of boom, arm bucket order control the tip position follow desired trajectory. This can be achieved through implementation automatic system for excavation task required understanding kinematics backhoe excavator. paper focuses on mathematical kinematic...
A geometric, or theoretical, stress-concentration factor is the ratio of actual maximum stress at discontinuity to nominal stress. Stress concentrations occur when there are irregularities in geometry material a structural component that cause an interruption flow This arises from such details as holes, grooves, notches, and fillets. detailed understanding concentration around hole essential for optimal design resilience mechanical failure. Therefore, structures, it study effects polygonal...
Abstract Differential longitudinal thermal expansion between the shell and tube bundle is a well-known problem in fixed tubesheet heat exchanger design. An bellows provide flexibility for also function as pressure retaining part. In this paper, guidelines design of flanged flued type (thick wall) available international codes standards including ASME VIII-1 2, EN-13445, TEMA EJMA are presented. These compared terms information thick wall with regard to condition applicability formula, spring...
Flanged and flued type expansion joint (thick wall bellow) used as an integral part of many shell tube heat exchanger where process conditions produce differential between tubes. It provides flexibility for thermal also functions a pressure retaining part. Design joints is usually based on trial error method in which initial geometry must be assumed, accordingly maximum stresses spring rate are calculated. Inadequate selection leads to higher tubesheet bellow thickness, increases cost...
At present, excavation machines are widely used in the mining industries, forestry work and construction industries. These of heavy size for duty work, but they costlier complex nature. not required to carry out digging operation efficiently particularly light so economical. So, there is a scope develop backhoe attachment it can be applicable autonomous excavation, this purpose, necessary determine kinematic working range using solid modelling. This paper focuses on evaluation proposed...
In industries, many unexpected failures of machine components occurs due to lack proper design, sudden changes that happen during working conditions and pre-existing geometrical irregularities. The geometric discontinuities cannot be avoided as they fulfill functional requirements. shaft or round bar with shoulder fillet is one the under different loading conditions. present work, filleted shaft/round bending taken for study stress concentration factor was evaluated. Finite element analysis...
Abrasive Jet Machine (AJM) widely used for cutting brittle materials. The present study focus on experimental investigation performance parameters like Material Removal Rate (MRR) and Surface Roughness (SR) with variation in controlling parameters. Here, air pressure, abrasive particle temperature speed of mixing chamber considered as measurement their effects AJM. Compare to conventional method AJM, unique feature heating jacket rotary mechanism provided the newly developed AJM purpose....
Offshore, bridges, steel structures, and heavy-duty equipment all use hollow cantilever beams. The great challenge for design engineers is to provide a better robust of beam that can withstand applied load with optimized parameters. According the literature review, strengthening or plate be accomplished by providing transversal and/or longitudinal stiffeners post-buckling lateral buckling moments. Thus, it not sufficient designers only part component minimum weight cost while ensuring...
