本文提出了一种新型液压减振器的优化设计方法，该减振器采用具有表观黏度的电流变液（ER），该电流变液具有电场修饰的表观黏度。将优化设计的ER减振器与现有的带计量销的减振器的结果进行比较，结果表明，在含有ER减振器的系统中，轻体（1250kg）的最大加速度与重体（2250kg）的最大加速度接近，而在含有ER减振器的系统中，前者的最大加速度约为后者的2倍。此外，结果表明，与先前论文中提出的在减振器中使用恒定阻力的方法相比，使用优化设计方法获得的最大加速度降低了0.9 ~ 8.9%。
We propose an optimum design method for a new of type hydraulic shock absorber in which the resisting force matches that of impacts of various masses using electrorheological (ER) fluid having apparent viscosity that can be modified with an electric field. Comparing the results of the optimally designed ER shock absorber and an existing shock absorber with a metering pin, it is shown that the maximum acceleration of a light body (1250kg) nearly equals that of a heavy body (2250kg) during impact for a system containing the ER shock absorber, while the maximum acceleration of the former is about 2 times that of the latter during impact for a system containing the existing shock absorber. In addition, it is shown that the maximum accelerations obtained using the optimum design method are reduced by 0.9∼8.9% compared with those obtained using a method proposed in a previous paper using a constant resisting force in the shock absorber.
