A kind of speed-measuring method of rotary switch speed measuring equipment, comprise the following steps: a, etc. the string test model set up: to testee, waits the foundation of string test model by its drive mechanism; B, data acquisition: adopt angular-rate sensor to carry out the sampling of angular velocity; C, physical computing: utilize the string test models such as physical motion principle resume, and calculate; D, data show: the rotating speed that shows testee at display unit.
Deng analysis and the foundation of string test model, adopt the string relation that waits of circular motion to find the relationship model of arc length in engineering application, when waiting string test model to set up, central angle satisfies 0 °≤θ≤180 °, and wherein, model variable is θ, R.
Circular movement pattern linear velocity test philosophy, take anglec of rotation θ=55 °, R=100.5mm describes as example, wherein s is arc length corresponding to θ angle, the DA clockwise direction rotates to DB, angular transducer is installed on the D point, and V master closes, V master divides by the circular motion rate calculations as follows:
Due to speed V=ds/dt; Angular velocity omega=d θ/dt;
Due to s=θ * R;
: the * R of ds/dt=d θ * R/dt=(d θ/dt);
That is: V=ω * R;
By the angular velocity speed pickup, moving displacement, time data Direct Sampling are also processed the calculating sampling data automatically.
The engineering application actual needs is tested the D point axle moving knife AD of place namely, and V master closes; DB namely, V master divides; DC, namely V ground connection is closed, the speed V of motion, but because angular transducer can only be arranged on the d point.
Shown in Fig. 1 three link motion principle sketches, three connecting rods 1 and rotary switch equipment 2 fixed pivots are respectively D, d, and wherein: d is that main shaft is exported by mechanism's Direct Torque, is transferred to driven shaft D through three connecting rods 1 such as ad.In same time t, as clockwise db during 85 ° of motions of ad, AD 55 ° of DB of motion clockwise simultaneously; Equally, the db dc 71 ° time that moves clockwise, DB 45 ° of DC of motion clockwise simultaneously;

Shown in the string models such as Fig. 2, foundation waits string model A D → BD, A ' D → B ' D, wherein, R=100.5mm; R '=68.69mm; θ '=85 °, θ=55 ° motion service time is all t, chord length AB=A ' B '=92.81mm directly measures to get arc length AB=96.47mm; Arc length A ' B '=101.9mm.Due to arc length AB ≠ arc length A ' B '; Can get thus, setting the time that equates is t, and the linear velocity of A → B is V, the linear velocity V ' of A ' → B ', i.e. V＜V '; But satisfy certain length velocity relation: as V=κ V '.
By circular motion speed computing formula, above-mentioned length velocity relation is verified, known: θ=55 °, θ '=85 °, R=100.5mm, R '=68.69mm, and obtain the κ value.
By V=ds/dt; 1.
s=θ*R； ②
t=t’； ③
By 1. 2. 3.,
V=0.946V’； ④
That is: κ=0.946
Method is set up the test data model thus, the virtual string model △ A ' B ' D that waits is carried out in actual test model △ ABD position to be transformed, be set to when angular-rate sensor is self-defined: 355 ° of (AB/ θ ') *, wherein 355 ° is angular-rate sensor Validity Test angle.Be that angular-rate sensor test result reading value is V '.
