回转式推土机顶推架的强度计算,以往是按钢丝绳操纵且为单吊点来计算的。而目前推土机铲刀起落大都改用液压油缸控制。所以,推土机顶推架的强度计算应重新考虑。
The calculation of the strength of the pusher of the rotary bulldozer has been calculated according to the wire rope operation and the single hoisting point. At present, bulldozer blade landing and landing mostly use hydraulic cylinder control. Therefore, the calculation of the strength of the bulldozer pusher should be reconsidered.
