The scenario of rotor responses with the increase of the rotating speed is no-rub synchronous whirl [right arrow] a synchronous full annular rub [right arrow] a partial rub with forward whirl [right arrow] a partial rub with backward whirl [right arrow] dry whip as shown in Figure 3.
For rotor speed [omega] = 1.9, the response of the rotor is a partial rub with forward whirl as shown in Figure 3.
For the same rotor speed [omega] = 1.9, the desired controlled position is set as (1.1, 0, [omega]t - 2.5, [omega]) and the other values are not changed; the partial rub with forward whirl of rotor is also stabilized to no-rub motion successfully as shown in Figure 5.
In addition, the company is restaging its Deep Heating pain relief
rub with new streamlined packaging that emphasizes the product's heat generating ability while offering retailers greater merchandising flexibility.
