“…Since we could not find any other linear MR brakes that worked in shear mode, we could only compare our new design with the existing conventional designs. A piston-cylinder device from the literature (Li et al, 2006) that was already optimized by its developers was especially a good representative sample for this comparison. As shown in Table 2, this brake has almost the same size as ours since the cross-sectional areas of both brakes are almost identical, and as the normalized volumes show, the length of the conventional brake is a little longer than ours.…”

“…To illustrate the drawback of the existing designs in terms of off-state force contribution, a designed MR brake in the literature (Li et al, 2006) is analyzed using the formulas shown in equations (2) and (3). The geometric parameters of the MR brake and the constants estimated during the computation are shown in Table 1.…”

“…The drawback of the conventional design was illustrated by Alkan et al [15]. Off-state force due to the pressure difference was calculated as 71 N for Li et al's design at 30 mm/s [9]. This disadvantage restricts the use of the conventional design in applications such as robotics where low off-state forces are desired.…”

“…Nonetheless, the off-state force is approximately 270 N. Its ratio of maximum force to off-state friction force is about 7.8. Another linear MR brake, with a size of 130 mm in length and 30 mm in diameter, is used in a prosthetics application [9]. For this brake, the maximum force is 942 N and off-state friction is about 94 N. Its ratio is about 10.…”
