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.

作为中国传统文化之主体的儒家伦理，已经确立了中国传统文化的"基德"或"母德"，这是在长达2000多年历史发展中形成的，经过先秦时期的百家争鸣，形成了独树一帜的儒家思想，董仲舒提出"抑黜百家、独尊儒术"的建议，确立了儒家在中国社会的统治地位。经过以后历代的兼收并蓄和对立融合，发展成为儒、道、佛融合一体的宋明理学，近代中国社会对儒家思想的批判性发展，促使人们对儒家伦理思想进行时代的反思。荣格的分析心理学思想为东西方道德观的比较提供了一种独特的研究视角。
