With the rapid development of Internet technology in China, mechanical drawing plays a more and more important role in social development and practice. The main purpose is to use the course of mechanical drawing to accurately represent the appearance, size, principle and technology of the machine. It is often called the language of communication in the industry. In order to make mechanical drawing better applied and practiced, and to make maximum use of Internet technical resources, the establishment of multimedia courseware teaching mechanism is the development trend of mechanical drawing.In order to adapt to the trend of network information, based on the multimedia environment, this paper studies the application of animation technology in mechanical drawing teaching, and constructs a small multimedia teaching platform. Through the explanation of animation courseware, students can better understand the making and principle of mechanical drawing, and cultivate students' divergent thinking. The teaching platform combines teaching material knowledge with practice to deepen students' understanding of the basic content of mechanical drawing. Finally, the rationality and practicability of the system are analyzed by investigating the platform users. The results show that the application of animation technology in mechanical drawing teaching is reasonable and practical.
The Biomedical Engineering has well-developed very rapidly in recent times, and after the intervention in all areas of medicine of life and to increase the accuracy and security of medical operations, especially surgical, where he was previously relying on a doctor in a different surgeries and this was accompanied by a lot of mistakes and the length of time and lack of precision The work of the large holes in the human body and the loss of a large amount of blood and sometimes lead to death, so was the invention of surgical robot which replaces the doctor in an all surgeries provided with camera and arms of the holes for the purpose of surgery during the operation and the withdrawal of the damage to the outside of the human body as well as to the sewing section which was performed surgery on it.The surgical robot needs to study in order to avoid any error while doing any surgery being moved in all directions as well manufactured and metals used in precision manufacturing to prevent the interaction between the human body and the materials used.The surgical robot when conducting any surgery, it is exposed to Dynamic movements and to vibrations co-operation in this research study and analysis of rotational and transitional arm scalpel movements (process surgical scissors) where was derived kinetic equations transition and spin of the robot during movement, analyze and find a response to each interface and detailed in this Arm and find the natural frequencies and modes and foretelling a movement for all data and thus find, responsive to the final robot through which to draw its own curves public movements during surgical operations.By introducing the mechanical specifications and dimensional modeling Android in Ansys program by drawing the paper model and the using of Scissors force, who is the surgical operations and give the suggestions in a note to the Islamic group Ansys program as well as the moments affecting bends and shear forces for the purpose of simulation model with reality.Where they discussed outputs, data movement, distortions, and distractions in the form and after the study results are analyzed-style geometric Medical to optimize the design and to avoid any error surgeons during surgical operations Mather the accuracy of the results and this in turn gives the safety and protection of persons during the surgical procedure.
This study was carried out to design and fabricate a cost effective and efficient compression – extension machine to alleviate the problem of the dearth of equipment in our laboratories in most of our higher institutions. In carrying out the project work a thorough study of the foreign testers and the requirements of the Nigerian industrial standards, was done. Design drawings and calculations were established and the machine was fabricated with well selected materials and components all sourced locally. The performance of the fabricated machine was finally evaluated against a standard foreign machine employing a stress-strain diagram that enable the comparison of the mechanical properties of aluminum. Test results reveal absolute errors of measurement of 3.79%, 3.97% 2.17% and 2.53% for ultimate tensile strength, Young’s modulus, yield strength and ductility. Performance characteristic in the various mechanical tests evaluated was found satisfactory. The machine provides a low cost solution for engineering and engineering technology programs that wish to expand their material testing capabilities but are not capable of funding the acquisition of commercially available compression and extension testing machines.
New mode of measurement and draft in mechanical drawing based on reverse engineering is presented to reflect the idea of modern engineering design on teaching practice. Traditional measurement tools are replaced by three-dimensional scanner, whereas graphics processing is performed by using CAD technology. The processing includes three steps. Firstly, point cloud of part surface shape is obtained through scanning. Secondly, point cloud images are joined, filtered and latticed in Geomagic, which is application software of CAD. Finally, the processed point cloud is imported into Catia to reconstruct surface and three-dimensional geometric model. An innovative method of measurement and draft is accordingly proposed, which combines teaching and practices and helps to cultivate the innovative idea and abilities of students.
