Define the braking torque T1 corresponding to the maximum deceleration in this condition (Te>T1), in which frictional braking need not work. (2) Based on study[8], if the rated electromagnetic braking torque is higher than a braking torque value (T2), the electromagnetic rotor will rise to more than 300℃ due to the excessive heat, leading to drastic changes in performance of the rotor’s magnetic permeability, and significantly reduction of the electromagnetic braking torque.

Machining cost reduction achieved through the increase of material removal rate and tool life without compromising surface integrity even for hard-to-machine materials is highly desirable; a paradigm being the cutting of hardened steels by CBN tools at increased speeds or as it is usually referred in the relevant literature high speed hard cutting.
The designation of the optimal technological data requires a mathematical model that is able to accurately specify these limit values.

This testing done to obtain the data based on the tensile test.
The data then automatically produced by the machine.
All data are recorded and calculated to obtain the average result.
The unit consists of a gimbaled arm to which the pin is attached, a fixture which accommodates disks up to 165 mm in diameter & 8 mm thick, an electronic force sensor for measuring the friction force, and a computer software for displaying the parameters, printing, or storing data for analysis.
The data also was supported by Mandal et. al,. [3].stated that the increasing in the yield strength and ultimate tensile strength can be attributed to the decrease in the grain size and hardening due to TiB2 particles.

Using the data in Table 2, the elastic modulus of LW-B and LW-S are less than that of LW-M.
In the initial of loading, the data acquisition system records the experimental data simultaneously and shows that the beams have a good capacity of linear deformation.

Then the billets were additionally rolled at ambient temperature with a total reduction of 80% down to a final thickness of ~4 mm using a two-roller mill.
The data in Figure 4 summaries the tensile test obtained at different strain rates and temperatures.
It is clearly seen that serrated plastic flow (type A) in the alloy appears only at ambient temperature and intermediate strain rate (filled data points).
In the case of open data points ones mean that no serrations were observed.

It is shown road load response and the power spectrum density data of various practical road conditions in Fig. 2.
Therefore, it is difficult to attain economical and reasonable design as well as make reduction reliability on design.
Therefore, for reasonable design to attain design life of leaf spring assembly, it is necessary to determine the fatigue design criterion from the fatigue data obtained under the most severe actual condition [5].
And the data measured on road load response was used to obtain the fatigue load-life relation to develop the new fatigue design criterion of leaf spring.
And next, the damage analysis of road load response data was carried out.
