Barrel Bending Artillery Accuracy Of Analysis

The article through dividing cannon tube curve to the two main instances of oneself weight curve and hot curve, analyzes the produce mechanism of oneself weight curve, carries through camber and cannon mouth angle calculating and analyzes oneself weight curve change instance with angle of fire. Following this, it stressfully analyzes the produce mechanism of cannon tube hot curve. Aimed at tube curve by sun shining, it analyzes and calculates the instance of curve when tube up and down face have difference in temperature, and discourses upon it influenced degree to cannon firing accuracy. For hot spread asymmetry caused tube curve, it explains it's form cause. For irregularly hot stress acting tube curve , it stressfully analyzes effect of body tube wall thickness difference.Based on this, it analyzes effect to cannon mouth vibration caused by tube curve bringing bourdon domino effect. From deducing formula, it calculated connection of tube camber and cannon jump of angle, and discussed feasibility of carrying through shot modifying by tube camber. At last it pertinently brought forward some solved methods and measures which can decrease or amend the effect of tube curve to cannon firing accuracy. It is hoping us can grasp each kind of influence reason that affect cannon firing accuracy how size influence and how essentialprobability in actual firing. It is hoping be help to effectively improve cannon firing accuracy and first-round-hit probability...
