安全装置

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.

Since the installation of fire safety is not a part of a building structure and the seismic building design code does not include fire water pipings, the design of them in Taiwan does usually not consider the seismic effect. This study first collected and summarized the relevant seismic design codes and fire control standards from U.S., Japan, China and Taiwan to understand the internationally adopted methods for seismic from designs of fire water pipings. This study also gathered engineering cases and photographs of the installation of the shock resistance hangers of fire water pipings in high technology factory buildings. Then, this study presented a proposal for seismic design principles. we hope this can attract attentions from government authorities and the fire safety business sector and to rise concerns of the seismic design of fire safety installation; and therefore set up a clear and practical criterion for the engineers and finally reduce the damage of post earthquake fires.

由於消防安全设备向来都是归属於非结构物，国内一般在进行结构设计时并未将消防管路纳入耐震设计的范畴内，本研究系针对建筑物内消防管路的耐震设计为议题，搜集并整理出美国、日本、大陆及国内等相关建筑和消防规范的执行现况，以了解目前国际上在消防管路方面所采取的耐震设计手法，本研究也同时汇整了目前国内重大科技厂房新建工程在消防撒水管路耐震吊架上，所采用的设计案例和实际装置后照片，祈能藉由此案例唤起国内相关主管单位和消防业界对建筑物内消防安全设备耐震力设计的关注，共同研议订定出明确、实用且可供大家遵循的消防安全设备耐震设计准则，以减低国内在地震后火灾所造成的危害。
