随着大型颚式破碎机出现，对该机型的防震性能提出了越来越高的要求。传统上，为了尽量减小颚式破碎机本身惯性力所产生的振动．一般都在飞轮或带轮上加质量平衡块。另外，该机型拉紧弹簧装置在一定程度上，也能抑制动颚惯性力所产生的振动大小[2]。本文将从矢量角度出发，对复 With the emergence of large-scale jaw crusher, the shockproof performance of the model has put forward higher and higher requirements. Traditionally, in order to minimize the vibration generated by the inertia of the jaw crusher itself. Generally in the flywheel or pulley plus mass balance block. In addition, the model tensioning spring device to a certain extent, can also inhibit the dynamic force generated by the dynamic jaw size vibration [2]. This article will be from the vector point of view, complex
