VL - 6 IS - 1 SE - Research Article DO - 10.15625/0866-7136/10401 UR - https://vjs.ac.vn/index.php/vjmech/article/view/10401 SP - 9-13 AB - <p>In- this article the vibration of hanging pendulum in hammer crusher is investigated in case when the ratio <em>p<sup>2</sup> /l<sup>2</sup> </em>is not very small in comparison with 1. It turned out that the suitable parameters in this case are 33% larger than that in the case <em>p<sup>2</sup> /l<sup>2</sup></em> &lt;&lt;1 [1]. Because there is the friction the pendulum vibrates not around straight line OA but around A' with an angle <em>x<sub>0 </sub></em>determined by  (4.3), (4.4 ).<em></em></p> ER -
