1.摩托车手柄振感评价应用模糊图形评价法对摩托车通过颠簸时手柄的振感进行评价。应用模糊图形评分表对手柄的振动感度进行了评价。(2)四次方振动剂量值与感觉分数之间的关系满足费克纳定律，阐明了根据试验条件对感觉的特征进行分类。汽车橡胶悬置的刚度优化方法为了改善操作人员周围的环境，降低振动是非常重要的。对橡胶悬置的刚度组合进行了优化，得到了以下结果：(3)进行了co…基于多输入单输出技术对悬架系统进行了更多的贡献分析和激励试验，明确了轮胎、车轮和减振器系统的耦合振动是影响车辆平顺性的主要因素。(4)灵敏度分析表明，前轮橡胶悬置的刚度对平顺性起主导作用。(5)前轮橡胶悬置刚度降低30%后，平顺性提高了4.5分贝，验证了所提方法对优化橡胶悬置刚度组合以提高平顺性的有效性。车祸中儿童滥用CRS的动态分析利用解析虚拟模型分析CRS的误用对儿童造成的损害。根据研究结果，运用多元回归分析提出了儿童安全带的安全标准，得到了以下结论：(1)安全带的误用是导致儿童伤害的最主要因素。(2)明确了对误用安全带最敏感的损伤标准是头颈部张力的GSI。较少

1. An Evaluation of Feeling of the Vibration on Handle of MotorcycleAn evaluation of the feeling of the vibration on handle while motorcycle passes bumps is carried out by applying Fuzzy Graphic Rating Scale. And the effectiveness of the method is confirmed.(1) The evaluation of the feeling of the vibration on handle was carried out by applying Fuzzy Graphic Rating Scale. And it is clarified that the criterion of the feeling is represented by Membership function.(2) The relation ship between Fourth Power Vibration Dose Value and feeling score fulfills the Fechner's law, and it is clarified that the characteristics of the feeling by the test condition can be categorized.2. A Stiffness Optimization Procedure for Automotive Rubber MountsIn order to improve the environment surrounding operators, the reduction of vibration is of great importance. The optimization of the combination of the stiffness of the rubber mount is conducted, and following results are obtained.(3) By carrying out a co … More ntribution analysis and excitation experiment of suspension system based on a multi-input single-output technique, it was clarified that the coupled vibration of tire, wheel and absorber system is dominant for the vibration and noise.(4) It was clarified that the stiffness of the front rubber mounts in front wheels are dominant for ride comfort from a sensitivity analysis.(5) The 30 % reduction of the stiffness of the front rubber mount improved 4.5 dB of ride comfort, and it was verified that the proposed method is effective for the optimization of the combination of the stiffness of rubber mounts for the improvement of ride comfort.3. Dynamic Analysis of Child in Misused CRS During Car AccidentThe analysis of the damages on Children caused by misuses of CRS is carried out by using a analytical dummy model. From the results, a safety criterion is proposed by applying a multi regressive analysis and the following results are obtained.(1) It is clarified that the misuse of the harness is most dominant for the injury of children.(2) It is clarified that the most sensitive injury criterion to the misuse is GSI on the head and neck tension.
