本文应用苏联学者符拉索夫的开口薄壁杆件理论建立了车辆底架强度计算的数学模型和相应的计算程序,並用例证阐明了开口薄壁杆件考虑约束扭转的必要性。
In this paper, the mathematic model and the corresponding calculation program of vehicle chassis frame strength are established by using the open thin-walled rod theory of Soviet scholar Vlasov, and the necessity of the constrained torsion of the thin-walled open-section rod is illustrated with examples.
