The gravity center position of truck crane boom is necessary for boom structural design, crane load capacity setting and counterweight design. The position of the boom's gravity center is affected by the deflection caused by gravity. Therefore, firstly, the segment by segment hardening and superposition method is adopted to derive the analytical formula of the boom's deflection, and then the center of gravity coordinates is calculated according to the boom's structure and deflection solution. The center of gravity coordinate calculation program of crane boom is compiled by using Microsoft Visual Studio, and the it is carried out by taking the 5-section boom of XCT25L5 crane as an example. The comparison with the finite element analysis results shows that the algorithm in this paper is satisfied, and the average error is within 10%. In this study, a simple and practical calculation formula of boom center of gravity coordinates is derived through theoretical analysis, and the rapid calculation of boom center of gravity coordinates is realized through software, which can be used in various R & D designs and reduce the development cycle and cost.
