机组及泵房振动问题日益突出,给泵站带来的威胁不容忽视。研究了大型泵站立式全调节轴流泵振动特性,为后续的工程建设及类似工程的运行管理提供参考。主要以江都四站4号泵机组及7号泵机组为例,通过对两台机组进行多工况、多测点、多振动参数的现场测试,整理数据,绘制相应的振幅统计、时域波形、位移频谱图,分析各主要测点的振动幅值、振动频率随角度、水位的变化规律,得出机组在不同叶片运行角度下、不同水位差的条件下立式轴流泵叶轮外壳振动变化较为明显,故水泵振动值大主要受水力和机械因素影响。

目的:探讨人-器械相互作用过程中的动力学关系,为后期优化踏板技术提供理论基础。方法:在life Mo D中建立19个环节的多体动力学模型和助跳板,并展开助跳板力学特性的仿真研究。结果:踏跳过程中体操运动员受到的踏板反作用力峰值随着助跳板弹簧的刚度、阻尼以及板面体刚度的增加而增大,而随着板面体阻尼的增加而减小;增加助跳板弹簧的刚度能有效地提高体操运动员踏板后的垂直起跳速度,而改变助跳板弹簧的阻尼以及板面体的刚度和阻尼则影响不明显;增加助跳板面体的阻尼虽能减小踏板反作用力的峰值,但其负载率也明显增大。建议在满足人体肌骨系统能够承载的生理范围内,适当增加助跳板的刚度有助于完成更高难度的技术动作。
