Abstract

The invention discloses a locomotive body deflection measurement method. The method comprises the steps that height values of a first preset point and a second preset point of the transverse center of a locomotive chassis to a preset horizontal reference plane are respectively measured, and a first height value and a second height value are obtained via the measured height values; the height values of a third preset point, a fourth preset point, a fifth preset point and a sixth preset point of the longitudinal two ends of the locomotive chassis to the preset horizontal reference plane are respectively measured, and a third height value, a fourth height value, a fifth height value and a sixth height value are obtained via the measured height values respectively; and locomotive body deflection is calculated based on the height values. Splicing error caused by locomotive body side beams can be reduced and measurement error of side beam height can be reduced in the measurement process of locomotive body deflection through measurement of an average height value based on the basic principles of geometry so that measurement precision of locomotive body deflection can be enhanced.

Description

technical field

[0001] The embodiments of the present invention relate to the field of locomotive manufacturing, and in particular to a method for measuring the deflection of a locomotive body. Background technique

[0002] The side beam of the locomotive body is a splicing structure, and there will be splicing errors during the splicing process of the side girders. Therefore, in the process of measuring the deflection of the locomotive body, if the original direct measurement method of height is used, the splicing error will be directly implanted into the deflection Among the measurement values, it affects the actual deflection value of the locomotive body. Contents of the invention

[0003] The invention provides a method for measuring the deflection of a locomotive body, which can reduce splicing errors caused by side beams of the locomotive body during the measurement process of the deflection of the locomotive body and improve the measurement accuracy of the deflectio...
