Break through the teaching mode and drive creative thinking

After the introduction of Inventor Professional 2008, the Department of Engineering Graphics of Dalian University of Technology continued to practice "the teaching model of engineering graphics training based on the practical ability of three-dimensional design", and formed a three-dimensional design based on the content, hours, and teaching methods in line with reality 3. Strongly implementable, teaching model with popularization value that fosters modern design concepts and engineering awareness.

Project Background

Since 1996, the Department of Engineering Graphics at the School of Mechanical Engineering, Dalian University of Technology has begun to use a variety of software to gradually carry out teaching practice activities based on three-dimensional design in the teaching of "painting collection and mechanical drawing". To promote the concept of three-dimensional design, students use three-dimensional modeling and two-dimensional expression in the engineering drawing course to realize the preliminary design of parts. In 2007, the school introduced Inventor Professional 2008, began to teach the software throughout the school, and through the formation of scientific, unified and flexible teaching plans and set reasonable practical teaching tasks, formed a three-dimensional design based on the cultivation of modern design concepts and engineering awareness Teaching model. The project "Training Mode of Engineering Drawing Course Based on Practical Ability Training of Three-dimensional Design" won the third prize of Primary Teaching Achievement of Dalian University of Technology in 2008.

Easily achieve seamless transition with AutoCAD

With Inventor's recognizable icons, AutoCAD-compatible shortcut keys, cursor prompts, and a familiar design environment, students easily completed the transition from AutoCAD to Inventor in a course based on 3D design practice training.

Design accelerator to increase modeling speed

Using the Inventor design accelerator spring generation module, the students quickly completed the valve spring design and the reducer gear design in practice. Creating 3D models through functional requirements saves designers a lot of geometric modeling time and enables them to focus more on innovative design. "Inventor's good data structure and user interface and design of the accelerator module make the software easy to operate and fast to model." In the teaching practice, the teachers of Dalian University of Technology in Engineering Graphics gave high marks to Inventor's ease of use.

Dynamic simulation demonstration to easily experience the working principle

In the early stages of design, students often fail to understand the rationality of design ideas in advance. With the help of Inventor's motion restraint and over-constraint functions, through dynamic simulation demonstration, students can clearly understand the principle of motion.

With automatic analysis of assembly constraints, not only can the rigid body be identified and converted into the correct simulated motion connection, but also the standard motion connection can be selected and applied from the motion connection library. The wiping coefficient is described in detail.

Easy implementation of design intent

Using the geometric constraint functions and sketch modification tools of Inventor sketching tools, students can evaluate different design options before creating parts and assembly models. Combining the setting of colors and lines, the design concept is completely and clearly expressed.

From initial modeling to generating digital prototypes, Inventor can create high-quality surface models. Zebra pattern and Gaussian analysis tools can also check the tangency, continuity and curvature of curved surfaces. In the course of sheet metal design, students only need to define the material thickness, bending line and relief angle in the sheet metal style, they can design the entity according to their own imagination. The linear unfolding method and the custom bending table can also better control the unfolding geometry.

Comprehensive digital prototype solution

With the help of a comprehensive and integrated set of design tools provided by Inventor Professional, students can create accurate 3D digital prototypes and verify the design's appearance, assembly and function in the early stages of design. Inventor's built-in motion simulation and stress analysis functions can also help them verify and optimize their designs.

With the help of Inventor's powerful tools, students have a strong interest in designing courses. Driven by interest, nearly a thousand students consciously conducted a deeper study of Inventor software design functions, and some students used the software to design and participate in mechanical design competitions.

"With the help of Inventor software, everything you can think of can be achieved." So far, teachers have expressed satisfaction with the teaching practice of Inventor software.

effect

With unremitting efforts, the Teaching and Research Section of Engineering Graphics of Dalian University of Technology has broken through the traditional teaching mode, and has closely integrated new content such as 3D CAD and computer modeling with the classic content of engineering drawing courses, which has increased the interest of students in 3D creative design. Their "Descriptive Geometry and Mechanical Drawing" course was rated as the 2007 National Excellent Course.
