Considering the efficient use of energy and environmental pollution, people's lives tend to energy saving and environmental protection, and energy saving electric vehicles has gradually been widely used. Through combining theoretical analysis, numerical simulation, system design and experimental validation, based on studying electric vehicle body design principles, the experiment optimized electric vehicle body design, and reduced the weight of the vehicle effectively. Its performance becomes more advanced, and the application becomes more economical and safe. By using Solidworks software, lightweight electric vehicle body structure of two-dimensional design and three-dimensional modeling was built to reach practical requirements. The body structure design is original and simple, which has good practical value.

Basic Ideas

Abstract The concept of Computer Aided Engineering (CAE) was first proposed by J. Lemon at SDRC, and has been widely accepted in automotive industries. CAE numerically estimates the performance of automobiles and proposes alternative ideas that lead to the higher performance without building prototypes. However, most automotive designers cannot directly utilize CAE since specific well-trained engineers are required to achieve sophisticated operations. Moreover, CAE requires a huge amount of time and many modelers to construct an analysis model. In this paper, we propose a new concept of CAE, First Order Analysis (FOA), in order to overcome these problems and to quickly obtain optimal designs. The basic ideas include (1) graphic interfaces for automotive designers using Microsoft/Excel (2) use of sophisticated formulations based on the theory of mechanics of material, (3) the topology optimization method. Further, some prototypes of software are presented to confirm the method for FOA presented here.

High Pressure Water Jet

Radial jet drilling (RJD) is an efficient approach for improving the productivity of wells in low permeability, marginal and coal-bed methane (CBM) reservoirs at a very low cost. It uses high-pressure water jet to drill lateral holes from a vertical wellbore. The length of the lateral holes is greatly influenced by the frictional resistance in the hole deflector. However, the hole deflector frictional resistance and structure design have not been well studied. This work fills that gap. Frictional resistances were measured in a full-scale experiment and calculated by numerical simulation. The structure of the hole deflector was parameterized and a geometric model was developed to design the hole deflector track. An empirical model was then established to predict the frictional resistance as a function of the hole deflector structure parameters and an optimization method for designing the hole deflector was proposed. Finally, four types of hole deflectors were optimized using this method. The results show good agreement between the numerical simulation and the experimental data. The model error is within 11.6%. The bend radius R and exit angle β are the key factors affecting the performance of the hole deflector. The validation test was conducted for a case hole deflector (5½ in. casing). The measured frictional resistance was decreased from 31.44 N to 23.16 N by 26.34%. The results from this research could serve as a reference for the design of hole deflectors for radial jet drilling.
