Efficient Machine

In industry material handling is very important. For that purpose efficient machine is needed. In modern days the electric crane plays important role to fulfil that requirement. It is economical, effective, less time consuming, more safety, and flexible for uses. In industry the safety is most important factor for any material handling machine which deals with the heavy load depending on the capacity. In electric crane the safety keeps on first priority. In this paper we design the electric crane which is more economical, less time consumable, with more safety and the easy to operate. It has two control units, one is at crane frame and one is at the remote location. This crane is able to operate by the single operator far from the crane and also can operate directly from the crane frame itself. Its lifting capacity is up to 500kg. according to load we carried out the load calculations for the crane frame or body & we created a 3D CAD model. Every component should able to deal with that load. To ensure that we carried out the analysis of the whole assembly in ANSYS 19.2. In analysis we found that the whole assembly is able to handle the load which we suppose to apply on it. We implement the pulley reduction to reduce the load on motor and gearbox as well. We tried to keep crane more compact in size so that it consume less space in industry.

The article describes an attempt to address the automatized evaluation of student three-dimensional (3D) computer-aided design (CAD) models. The driving idea was conceptualized under the restraints of the COVID pandemic, driven by the problem of evaluating a large number of student 3D CAD models. The described computer solution can be implemented using any CAD computer application that supports customization. Test cases showed that the proposed solution was valid and could be used to evaluate many students’ 3D CAD models. The computer solution can also be used to help students to better understand how to create a 3D CAD model, thereby complying with the requirements of particular teachers.

In this paper, we present the first steps in the process of the modeling in ADAMS MBS of MSC software of the mechanical system of an articulated robot, with six revolute joints. The geometric 3D CAD model of the robot, identical to the real model, in the PARASOLID format, is imported into ADAMS/View and then are presented the necessary steps for building the kinematic model of the robot. We conducted this work, in order to help us in our future research, which will consist of kinematic and dynamic analysis and optimization of the robot motion.

Abstract The use of advanced simulation has become increasingly more important in the planning, design, and assessment phases of future fusion plasma diagnostics, and in the interpretation of experimental data from existing ones. The design cycle of complex reflectometry systems, such as the ones being planned for next generation machines (IDTT and DEMO), relies heavily on the results produced by synthetic diagnostics, used for system performance evaluation and prediction, both crucial in the design process decision making. These synthetic diagnostics need realistic representations of all system components to incorporate the main effects that shape their behavior. Some of the most important elements that are required to be well modelled and integrated in simulations are the wave launcher structures, such as the waveguides, tapers, and antennas, as well as the vessel wall structures and access to the plasma. The latter are of paramount importance and are often neglected in this type of studies. Faithfully modelling them is not an easy task, especially in 3D simulations. The procedure herein proposed consists in using CAD models of a given machine, together with parameterizable models of the launcher, to produce a description suited for Finite Difference Time Domain (FDTD) 3D simulation, combining the capabilities of real-world CAD design with the power of simulation. However, CAD model geometric descriptions are incompatible with the ones used by standard FDTD codes. CAD software usually outputs models in a tessellated mesh while FDTD simulators use Volumetric Pixel (VOXEL) descriptions. To solve this interface problem, we implemented a pipeline to automatically convert complex CAD models of tokamak vessel components and wave launcher structures to the VOXEL input required by REFMUL3, a full wave 3D Maxwell FDTD parallel code. To illustrate the full procedure, a complex reflectometry synthetic diagnostic for IDTT was setup, converted and simulated. This setup includes 3 antennas recessed into the vessel wall, for thermal protection, one for transmission and reception, and two just for reception.

Manufacturing Techniques

Laser Metal Deposition Shaping (LMDS) is a Rapid Manufacturing (RM) process that can be classified under the area of layered manufacturing techniques, where parts are built in layers. Parts of any complexity can be built directly from the 3D CAD model without much human intervention and requires minimum post-processing. In fact, LMDS technique can be recognized as multilayer laser cladding. Accordingly, it is necessary to perform the elementary laser cladding experiments with common metal powder so as to better understand the LMDS process. Then the characteristics of microstructure, composition and phase of as-deposited clads were analyzed through SEM and XRD, as well as relative model. The results prove that the microstructure of 316 stainless steel deposits is composed of the slender dendrites growing epitaxially from the substrate, and the composition is uniform without obvious segregation. Besides, it can be deduced from XRD diagram that the microstructure is composed of mono-phase γ.

Rapid Prototyping System

This paper presents a new complete CAD-driven rapid prototyping system for polystyrene. ModelAngelo, as it is called, consists of six subsystems featuring hardware and software. The system utilizes a virtual 3D CAD model to produce a set of commands used to control a 5-axis CNC Machine to move a heated-wire tool into a block of polystyrene to form the desired surface. The ultimate goal of ModelAngelo is to reach the stage of “what you see is what you get”. An overview of ModelAngelo system is first presented followed by a detailed discussion of ModelAngeloSoftware. The various mechanical subsystems responsible for realizing the final product are then described. Advantages and disadvantages of several tooltip designs are discussed and the best solution is selected. The main features of the robotic arm, which carry the tooltip is also discussed in detail. Finally ModelAngelo controller that manages the interaction between software and hardware is briefly highlighted and possible applications of ModelAngelo are suggested.
