以微型往复式电动锯锯切机构为研究对象,建立了运动学和动力学模型,该模型计入了运动副摩擦、各杆的实际质量及滑块的具体结构,利用数值计算方法进行了计算机模拟.计算结果表明,附加平衡块可以减小机构的冲击和振动.同时求得了使机构的冲击振动最小的平衡块质量与质心位置,并给出了反映冲击振动大小与平衡块质量和质心位置关系的立体图.
Taking the miniature reciprocating electric sawing mechanism as the research object, the kinematics and dynamics model was established. The model included the kinematic pair friction, the actual mass of each rod and the concrete structure of the slider. The numerical calculation method was used to calculate the computer The simulation results show that the additional weight can reduce the impact and vibration of the mechanism.At the same time, the mass and centroid position of the impact mass that minimizes the impact vibration of the mechanism are obtained and the influence of the impact vibration amplitude and the mass and center of mass The perspective of the relationship.
