Based on the current development of children's electric cars on the market, the design takes human engineering research as the starting point.
The Main Problems of the Existing Products in the Human Factors Engineering Human factors engineering is a new and rapidly developing interdisciplinary, involving a variety of disciplines, such as: physiology, psychology, anatomy, management, engineering, system science, science, safety science, environmental science, etc., whose application field is very broad.
There is no better products from the perspective of consumer health, such as the choice of materials, comfort.
Different materials have different characteristics, and what is important is that the materials influence the realization of the structure and function.

Design in Revit involves working with real objects, such as walls, foundations, columns, roofs, etc. that forms the engineering intuition, engineering thinking.

Engineering ability training is the core problem in engineering colleges and universities.
To achieve these changes and to improve the students' ability of engineering practice, the teaching reform of the course of mechanical design for mechanical engineering is very important.
Therefore, as one of the core courses in mechanical engineering, it is the key point of the teaching reform.
In the content of the course, the working principle, application characteristics must play as the basic context, to step by step give an appropriate plan for the course, including getting appropriate reduction of the theory teaching proportion, putting emphasis on the engineering application, size calculation, material and structure, the contents of the three parts.

A comparison of grain boundary engineering mechanisms in copper and brass Valerie Randle and Gregory Owen Materials Research Centre, School of Engineering, University of Wales Swansea, Swansea SA2 8PP, UK V.Randle@swansea.ac.uk, g.t.owen@swansea.ac.uk Keywords: Grain boundary engineering, twinning, electron back-scatter diffraction.
Grain boundary engineering (GBE) has been carried out on copper and brass.
Introduction 'Grain boundary engineering' (GBE), is the manipulation of grain boundary structure in order to improve material properties such as corrosion resistance, intergranular cracking or ductility.
Recently GBE in this class of materials has been reviewed and discussed in detail [1].
It is suggested that these two mechanisms are general for GBE materials.
