Efficiency versus receiver displacement Angle Efficiency ([eta]) for two (9[degrees]) coil transmitter 0 66.
The efficiency ([eta]) has been experimentally found for different receiver displacement angles ([theta]) and the results are shown in Table 2.
13; maximum story drift angle is 1/1105 in the 23rd floor, specification of frame core tube is less than the interlayer displacement angle maximum 1 / 800; structure the stiffness ratio of 1.
By comparing Figure 5 (c) and elastic time history analysis and response spectrum method calculated interlayer displacement angle did not exceed the allowable value of drift angle of 1 / 800, can meet the requirements of specification and transform of seismic wave interlayer displacement angle value, the overall to response spectrum curve near.
Under rare earthquake, the structure can still be kept upright, and the maximum displacement angle of the main direction is 1/294, which is less than the limit value of the norm 1/100.
According to the results, in above connections no resistance loss will be observed until the relative displacement angle
of story equals to 0.
It follows from (42) and (14) that the perihelion displacement angle
from this analytical method is given explicitly as
When the usual assumption that the motion be kept small is released, the restoring force becomes proportional to the sine of the displacement angle
(rather than to the displacement angle
itself) and the pendulum becomes a non-linear system.
According to Venturini algorithm there are two solutions, one is the input and output displacement angles
which are same ie [[phi].
