离心总督的设计与分析:综述

抽象的 -

总控制器的功能是每当有负载变化时保持指定限制内​​的发动机的速度。该设备几乎可以用于所有车辆。我们调查的目标,以确定最大的压力集中区域和地区当调速器绕其轴线旋转时,易于失效,测量这些应力的值。该分析是在Pro E的帮助下进行的。还计算了从基座的各种元件的位移,并绘制了图表。“手臂重量”的影响是我们研究的主要关心领域,考虑到所有计算手臂的重量。手臂的重量行为the centroid of the arms and when the governor assembly rotates, centrifugal force starts acting on the centroid of the arms and tends to deflect the arms, this deflection or bending is to be minimized. In our work, we have done the Stress analysis on a particular configuration of governor assembly and then various materials are suggested on a theoretical basis.

由发动机驱动的飞重机构与节流阀连接,并以类似于气动调速器的方式抵靠弹簧,从而产生基本相同的操作。离心调速器更复杂,设计和生产而不是气动governor. However, the centrifugal design is more sensitive to speed changes and hence is better suited to engines that experience large fluctuations in loading.

州长设计

设计过程

  • 所有腿的州长的设计标准彼此完全相同
  • 其6000 rad / sec的总轴向偏转不能超过2.3毫米。
  • 忽视面内载荷效应,基本的自然频率低于2000 Hz
  • The lengths L1 and L2 have the following relations: 1.4*L2
  • <= l1 <= 2.0 * l2。L1和L2必须合理且可比。腿的所有部分的宽度和厚度是恒定的。
  • 每条腿的厚度和宽度可以以0.25mm的增量变化
  • 厚度相对较小
  • 腿的短部分的高度为4毫米。
  • All edges of the legs (except the ones that connect to the shaft) are straight

结果和讨论

从调速器组件的各个部分的压力分析我们能够识别压力。调速器的轴向偏转与角速度,模型的角速度变化,获得了径向位移。对于各种角速度,获得了径向位移偏差的性质。从我们的研究来看,我们确定的是,随着角速度增加轴向位移增加。
