摘要

工作目标是确定提供门运动的指定特性的关闭机构的参数。研究方法:考虑锁机构的力学特性和接触相互作用,将带锁机构的门运动作为一个多质量动力系统进行计算机模拟。研究成果和新颖性。建立了带闭门器的门和带弹簧的门的计算机动力学模型。门的开启力力矩、门的关闭时间、门与框架碰撞时的角速度作为门关闭机构质量的标准。根据规定的开门力力矩,得到了闭门弹簧刚度和变形允许值的计算公式。比较了带闭门器和带弹簧的门的运动。确定提供所考虑的示例的门运动的指定特征的关闭机构的参数。结果表明,在相同开启力矩的情况下,闭门器与门框的碰撞速度小于带弹簧的闭门器与门框的碰撞速度。结论:建立了带闭门器的门和带弹簧的门的计算机动力学模型,可以在考虑闭门器和弹簧机构的惯性和力学特性的情况下确定门的运动特性。闭门弹簧的刚度和变形允许值可由两个位置的开门力的规定力矩确定。可以确定,门铰链中的空气阻力和摩擦力不能产生平滑关闭门所需的阻力力矩,而不会在有限的关闭时间内对框架产生强烈冲击。最小化关门时间和门与门框碰撞速度的质量标准是相互矛盾的。如果将其中一个标准替换为限制条件,则可以选择闭门机构的最佳参数。所开发的公式和计算机模型推荐用于限制门运动的装置的设计。

SIMULATION OF DOOR MOVEMENT WITH A CLOSING MECHANISM
The work objective is to determine the parameters of the closing mechanism that provide the specified characteristics of the door movement. Research method: computer simulation of the movement of a door with a lock mechanism as a multi-mass dynamic system, taking into account the mechanical characteristics and contact interaction of the lock mechanism. Research results and novelty. Computer dynamic models of a door with a door closer and a door with a spring have been developed. The moments of the door opening force, the closing time of the door, the angular velocity of the door at the time of impact with the frame are considered as the criteria for the quality of the door closing mechanism. Formulas are obtained that determine the permissible values of stiffness and deformation of the door closer spring according to the specified moments of the door opening force. The movement of doors with a door closer and with a spring is compared. The parameters of the closing mechanism providing the specified characteristics of the door movement of the considered example are determined. It is shown that with the same values of the opening force moments, the speed of impact with the frame in the case of the door closer is less than the door with a spring. Conclusions: The developed computer dynamic models of a door with a door closer and a door with a spring make it possible to determine the characteristics of the door movement taking into account the inertial and mechanical characteristics of the door closer and spring mechanisms. The permissible values of stiffness and deformation of the door closer spring can be determined by the specified moments of the door opening force in two positions. It is established that the forces of air resistance and friction in the hinges of the door cannot create the moment of resistance necessary for smooth closing of the door without a strong impact on the frame with a limited closing time. The quality criteria that minimize the closing time and the speed of impact of the door with the frame are contradictory. The choice of optimal parameters of the door closing mechanism is possible if one of the criteria is replaced by a restriction. The developed formulas and computer models are recommended for use in the design of devices that restrict the movement of doors.
