项目摘要

Purpose of the Research (described in the initial application, with a few modifications) Results1. To complete algorithms/programs in order to identify the magnetic spring function. Arrived at the expected stage.2. To study theoretically the accuracy of identification in the magnetic spring function in the static field. Arrived at the expected stage.3. To study experimentally the accuracy of identification in the magnetic spring function in the static field. Experimental apparati are completed and work is progressing.4. To identify experimentally the repulsing magnetic field via the eddy current. especially the ultra high speed object. Experimental apparati are completed and work is progressing.5. To study problems of nonlinear vibration, chaos in particular, running (flux shearing) resistance and vibration damping in the models of the previous items 3 and 4. Experimental apparati are completed and work is progressing.Derived Problems results6. Computer simulation of nonlinear vibrations.Arrived at the expected stage and many papers were published.7. Studies of accurate numeration and/or solutions as well as functions. Many extended problems were found and work is progressing.Plan for future reseaches It is concluded that an apparetus for achieving a transonic high speed corresponding to the previous item 4 is incomplete because of the difficulty of the over-stress in the rotating wheel. thus, we developed a method to neutralize the stress by blowing a gas from outside of the wheel with the pressure corresponding to the centrifugal stress. The basic design is completed, however, the construction of the system is postponed because of financial problems.

研究目的（在最初的申请中进行了描述，进行了一些修改）结果1。完成算法/程序以识别磁力弹簧功能。达到预期阶段。2．从理论上研究静磁场中磁弹簧函数的识别精度。达到预期阶段。3．实验研究静态场中磁弹簧函数的识别精度。实验装置已完成，工作正在进行中。 4．通过涡流实验识别排斥磁场。尤其是超高速物体。实验装置已完成，工作正在进行中。 5．研究前面第3项和第4项模型中的非线性振动问题，特别是混沌问题，运行（磁通剪切）阻力和振动阻尼问题。实验装置已完成，工作正在进行中。衍生问题结果6。非线性振动的计算机模拟。达到预期阶段，发表多篇论文。7．研究精确的计数和/或解决方案以及函数。发现了许多扩展问题，工作正在进行中。未来研究计划结论是，由于旋转轮中的过应力的困难，对应于前项4的用于实现跨音速高速的装置是不完整的。因此，我们开发了一种通过从车轮外部吹入与离心应力相对应的压力的气体来中和应力的方法。基本设计已经完成，但由于资金问题，系统建设被推迟。
