With the development of the transport, the traffic is more and more crowed. And another reason which is the price of the vehicle is cheaper. So much more people can buy the cars, thus, the road is more crowd, people should park their cars which need a lot of area, so we can see lots of parking lots in the city, but the classical parking system cannot reach the requirements nowadays. So, we should a new parking system. So, in this report, we will introduce a new parking lot and system, which includes the modelling, programming, material stress analysis and motors. At first, we reference the classical parking lots and some new parking lots. We find some problem about them which have not enough area and non-automated. Thus, we design a dimensional parking lot with programming. Which can realize automatic. Secondly, we use the inventor 2017 to build the model and analysis about stress concentration. We also use inventor to simulation the action about our parking lot. In the model, we use the hydraulic system to drive the lift, which can up and down to park the cars, and we create a new system to fix the wheels to make sure the cars cannot move in the movement procedure. Finally, our parking lot is an automatic and dimensional project. We will show you much more detail about our project, we hope our project will improve the parking lots to make people’s life better and convenient.
