In view of environmental pollution, energy shortage and urban traffic congestion and other issues, a drawer type retractable electric vehicle (REV) is designed. Through the establishment of the frame and the vehicle’s three-dimensional entity model, the frame of the static characteristics and modal characteristics are analyzed by using the finite element numerical simulation theory. The results show that the frame vertical stiffness is not reasonable, thereby improving the frame structure. Based on multi-body dynamics theory, the vehicle dynamics model is established, and the ride comfort of the vehicle is checked. The results show that the comfort of the vehicle is in line with the general requirements of the vehicle. The design and analysis method of this paper has enriched the design method of modern electric vehicle, which can embody the characteristics of light weight, clean energy, effective space utilization and so on, as well as has certain engineering application value.
