Research on Muzzle Disturbance of Track Tension Force Effecting on Self-propelled Gun

HAN Xiao-ping;WANG Yang;Academy of Armored Force Engineering;PLA Troop 66064;  
The self-propelled gun was set to research,the movement characters was analyzed,the prototype was established and the movements of muzzle center point effect by track tension force was researched. The result was as follows: the track tension force was stronger,the vertical displacement of body gravity center was lower; the self-propelled gun's movement effected by tension force was divided into two statements: tensioned and released. During firing period,when the track was tensioned,in different tension force,the maximum vertical displacement and maximum angular velocity of muzzle point were basically as the same,so as the release statement; the maximum number in tension statement is bigger than release statement; During in-bore period,the muzzle point was effect by track tension force,when the track was released,the fluctuation of vertical velocity was bigger; the tension force was stronger,the angular acceleration was smaller. So,in order to confirm the firing accuracy,the track system should be tensioned,the tension force was bigger,and the accuracy was higher.
