$\mathrm{\α}=\arctan \frac{(y_{21}+h_2)-(y_{11}+h_1)}{d}$

${\mathrm{\α}}^{\′}=\arctan \frac{(y_{22}+h_2)-(y_{21}+h_1)}{d}$

Wherein, h ₁Be the distance of front target datum line to target surface stand bottom, h ₂Be the distance of back target datum line to target surface stand bottom.O is laser instrument position on the initial time gun tube, and α is the angle on the self-propelled gun initial time vertical direction, y ₁₁By the laser beam of position o on preceding target surface the one-tenth hot spot to the vertical range of front target datum line, y ₂₁By arrive the vertical range of back target datum line at the laser beam of position o institute's one-tenths hot spot on the target surface of back; O ' is a certain moment laser instrument position in the self-propelled gun motion process, and α ' is the angle on this moment vertical direction of self-propelled gun, y ₁₂By the laser beam of position o ' on preceding target surface the one-tenth hot spot to the vertical range of front target datum line, y ₂₂By arrive the vertical range of back target datum line at the laser beam of position o ' institute's one-tenths hot spot on the target of back; D is the horizontal range between the target surface of front and back.Therefore can draw self-propelled gun gun tube actual deflection angle in vertical direction between position o and o ': Δ α=α '-α.

In like manner can get the deflection angle of horizontal direction.In test process, y ₁₁, y ₂₁, y ₁₂And y ₂₂Can obtain h by calculating the physical location of hot spot on target surface ₁, h ₂Obtain by actual measurement with d,

Step 3, the test of self-propelled gun tracking accuracy.

Set the self-propelled gun fire control system by the fixed curve motion, start multifreedom motion simulator 1 simultaneously, self-propelled gun gun tube setting in motion, front and back target surface 5 and 8 is followed the tracks of laser faculas and is moved, light spot image before and after gathering in real time in the target surface 5 and 8 is also handled the image coordinate that obtains hot spot, be converted to the actual coordinate on target surface, with the set-point of current time compare can obtain self-propelled gun in pitching and orientation to departure, through counting the performance indications such as tracking accuracy of tested self-propelled gun after a while.

The tracking accuracy computational methods of self-propelled gun are as shown in Figure 4: suppose the given gun fire control system of current time orientation and pitching to angle be respectively α _HAnd α _V, preceding target surface 5 moves to apart from the distance of right frame of front target stand and lower frame with gun tube and is respectively dH _fAnd dV _f, back target surface 8 moves to apart from the distance of right frame of back target stand and lower frame and is respectively dH _bAnd dV _b, can record in real time by corresponding displacement transducer.The current time hot spot is respectively (x at the coordinate of front and back target surface 5 and 8 _1f, y _1f), (x _1b, y _1b), then the angular deviation of current time self-propelled gun gun tube is

${{\mathrm{\&Delta;\&alpha;}}_V={\mathrm{\&alpha;}}_V-{\mathrm{\&alpha;}}_V^{\&prime;}=\mathrm{\&alpha;}}_V-\arctan \frac{({\mathrm{<figure-callout\; id="2"\; label="h"\; filenames="HDA0000068808450000011.png"\; state="\{\{state\}\}">h</figure-callout>}}_2+y_{1b}+d{V}_b)-(y_{1f}+d{V}_f)}{d}$

${\mathrm{\&Delta;\&alpha;}}_H={\mathrm{\&alpha;}}_H-{\mathrm{\&alpha;}}_H^{\&prime;}={\mathrm{\&alpha;}}_H-\arctan \frac{(x_{1b}+d{H}_b)-(x_{1f}+d{H}_f)}{d}$
