自行式起重机在不同状态不同载荷作用下整机的抗倾翻稳定性(简称起重机稳定性)是一项重要的性能指标。起重机稳定性的计算方法,多年来一直是以稳定性安全系数(简称稳定系数法)来表达。在GB3811-83《起重机设计规范》(简称《规范》)中,重新规定了新的计算表达方法——力矩法。《规范》为何不用稳定系数法,而采用力矩法,这在《规范》的编写说明(简称《编写说明》)中作了解释:“目前国内各类起重机验算抗倾翻稳定性时均采用稳定系数法,基本上沿用苏联五十年代的计算公式。以国外一些
Anti-rollover stability of self-propelled crane under different loads under different conditions (referred to as crane stability) is an important performance index. Crane stability calculation method, for many years has been based on the stability of the safety factor (referred to as the stability factor method) to express. In the GB3811-83 “Crane Design Code” (referred to as the “Code”), redefines the new calculation expression - torque method. The “Code” why not use the stability factor method, and the use of torque method, which “specification” in the preparation of instructions (referred to as “writing instructions”) explained: "At present, the stability of various types of domestic crane anti-rollover stability are used Coefficient method, basically follow the Soviet Union fifties formula.
