Optimal Design of Boom for Telescopic Boom Type Forklift Truck [PDF]
Journal of the Korean Society for Precision Engineering, 2020 In this paper, the boom structure of a telescopic boom-type forklift truck was analyzed using ANSYS, a finite element analysis program. As a result, 494.22 MPa exceeded 456.08 MPa, allowable stress of the material, in the second boom.

Review of Sonic Boom Prediction and Reduction Methods for Next Generation of Supersonic Aircraft
Aerospace, 2023 The reduction of sonic boom levels is the main challenge but also the key factor to start a new era of supersonic commercial flights. Since 1970, a FAA regulation has banned supersonic flights overland for unacceptable sonic booms at the ground, and many

Self-weight Balance Design of Portal Crane Boom [PDF]
E3S Web of Conferences, 2021 During the luffing of the portal crane, the height changing of the center of gravity of the boom needs to consume extra energy, which not only wastes energy, but also makes the luffing drive system need to use a larger motor.
