为分析曲线通过时车钩偏角对机车车体横向载荷的影响,建立机车与车辆的连挂关系,导出车钩偏角随曲线半径、车体长度、车钩长度、车体横移量变化的关系,构建单机和双机牵引机车车体的通用载荷方程,并考虑机车定距和二系簧横向等效刚度的影响,运用牛顿迭代法导出车体一、二位端的二系横向载荷。分析结果显示,车钩偏角对车体二位端所产生的二系横向力比一位端大;双机牵引时二位端的二系横向力比单机牵引时大,而一位端的二系横向力相差不大;曲线半径、车体及车钩长度、车体横移量和机车定距对二位端的二系横向力影响较大,对一位端的影响较小;二系簧与止挡合成横向等效刚度对二系横向力的影响较小。
In order to analyze the influence of the declination of the coupler on the transverse load of the locomotive body when the curve passing through, the connection between the locomotive and the vehicle is established. The relationship between the deflection angle of the coupler and the curve radius, body length, The general load equation of single and double tractor locomotive body is established. Considering the locomotive locating and the transverse equivalent stiffness of the secondary spring, Newton iteration method is used to derive the secondary and secondary transverse load of the body. The analysis results show that the second-line lateral force generated by the two sides of the body of the coupler at the two sides of the vehicle body is larger than that at one end of the vehicle body. The curve radius, body length and coupler length, vehicle body transverse displacement and locomotive distance have a great influence on the second-line transverse force at the two ends and less influence on one end. The second-line spring and the stopper compound The transverse equivalent stiffness has little effect on the secondary force.
