塑料管道和导管系统.热塑管.抗日夜外部连续冲击应力的试验方法 - Roll over protective structure ( rops ) is a device which installs on out of construction vehicle . the main functions are : when the vehicle rolling over . rops can prevent the vehicle from rolling over further , and reduce the possibility of rolling vehicle injures operator ; when the vehicle traveling on freezing soil . concrete and rock , it has large resist continuous impact ability ; when the vehicle overturning rops can support the whole vehicle . arrangement of falling object protective structure ( fops ) can block objects ( such as trees , rocks ) so that supply protection for operator . this problem is that research rolling over and falling objects protective structure of bulldozer by learning research condition of rops / fops and relative lay down international standard . on the base of theory analysis . detrudes counting formula of rops / fops deformation through founding mechanics analysis model of rops / fops at the stage of elasticity and plastoelastic . and finds a set of feasible nonlinear finite element analysis counting . lt calculates rops / fops plastoelastic deforma variable of 320hp bulldozer , bulldozer has been carried out by optimizing design method
其主要功能是：当车辆滚翻时， rops能刺入未冻土壤而阻止车辆的进一步滚翻，降低滚翻的车辆对系着安全带司机轧伤的可能性；保证rops在碰撞和冲击变形不大的地面(如冻土、混疑土上、岩石)时，能具有相当大的抗连续冲击能力；当车辆已经处于颠覆状态时，已经变形的rops应能支撑住整车。落物保护装置(简称fops ) ，其构件的布置方式要能遮蔽坠落的物体(如，树木、岩石等) ，以便对司机提供适当的保护。本课题主要通过了解国内外有关对rops fops的研究情况和有关国际标准的制定，对大型推土机倾翻和落物保护装置进行研究，在理论分析的基础上，通过建立rops fops的力学分析模型，推导弹性、弹塑性阶段rops fops变形的计算公式，建立一套可行的rops fops的非线性有限元分析计算方法。
