The basic approach of protecting people from being hurt or killed in an accident is to improve crashworthiness of vehicles. This paper starts with discussing theories and methods for vehicle passive safety design, which included experiential methods, analytic methods, multi-body dynamics methods, crash test methods and the finite element method. Emphasis will be paid to the basic FEM theories and algorithms of impact problems. Topics discussed include the governing equation, element discretization, hourglass control, time integration, material model, shell element algorithms and contact-impact algorithms. For more reliable simulation results, this paper then conducts study on how to accurately get material model parameters by combining the FEM method with experimental method, and develops relevant material test machine and parameter calculating software. Based on that, basic typical impact simulation and test validation study are conducted. On the basis of the above work, the paper studies the thin-shell structures'crashworthiness, which was affected by the following factors: spot-weld features, shell thickness, cross-section and pre-deformation. As to vehicle parts'crashworthiness, the paper conducts simulation study of designing energy-absorbing steering system and adaptive airbag system. A practical energy-absorbing steering wheel is designed as an example. In further depth research, the paper suggests several inverse quantificational methods for vehicle crashworthiness design based on the ideal crash characteristics. The above theories and methods are applied with good results through several practical vehicles' crashworthiness design and improvement.

As part of the study of social administration of Nanjing in the Republic of China, the thesis consists of 7 chapters: Chapter one explains the basic concepts of social administration and the development of modernization of Nanjing before 1927. It stresses the importance of social administration in city development through the depiction of social characteristics and problems of Nanjing. Chapter 2 introduced the theory of social administration of the Republic of China, under which the municipal institutions are structured. It focuses on the social theory of Sun Yat-sen and correlative comments of Jiang Kai-shi, which reflect the theoretic level and subjective intention of social reform of the Republic of China. Chapter 3 discusses the local autonomy of Nanjing of the Republic of China. The origin of democratic local autonomy theory and its influence over social administration are expatriated. The advantages and disadvantages of local autonomy are analyzed in detail. Chapter 4 focuses its discussion upon social rescue work, an important part of social administration, with general description of social rescue work in Nanjing and concludes the characteristics of social rescue work in the transition from the traditional to the modern society. Focusing on the prominent problem of the large flows and inflation of population of Nanjing, chapter 5 discusses the population and population management of Nanjing and outlines the population situation through analysis of the population problem, management methods and the current situation. Chapter 6 describes the unprecedentedly active citizen organizations and parties. The transform and changes of these organizations occurring under the new circumstances and their functions in social administration are analyzed to reveal the interactive function between government and social organizations in social administration. Chapter 7, the epilogue, makes theoretic evaluation of the characteristics of social administration and its revelation to the current society of Nanjing, hoping this research serves as a reference to the current time.
