Robust design of adjustable linear oil damper

To improve the damping capacity and decrease the manufacturing cost of damping adjustable oil damper, a new robust design method of oil damper was proposed based on optimal design. For the high machining precision of valve unit, the sensitivity parameters was determined according to the fluid dynamics, the skill of damping modulation and the requirement of dynamic capacity. Using the design parameters and their tolerance as variables, the robust design model was established by making the manufacturing cost, damping performance and its robustness as object. The experimental results indicate that the robust design method can decrease the demand of process precision and improve the robustness of damping performance.
