现行教科书和有关文献资料上关于摆锤式液压试验机力矩平衡方程式,因为没有考虑摆杆自身重力和平衡铊的重力作用,致使摆锤的实际重量和按文献上给出的力矩平衡式计算的摆锤重量相关很大。例如,正切摆式测力机构的300型液压式压力试验机,其最小摆锤的计算重量约是实际重量的 Existing textbooks and related literature on the pendulum hydraulic test machine torque balance equation, because it does not consider the pendulum gravity and the balance of thallium gravity, resulting in the actual weight of the pendulum and according to the literature given the balanced calculation of the torque Pendulum weight related great. For example, the tangent force measuring mechanism type 300 hydraulic pressure testing machine, the calculated minimum weight of the pendulum is about the actual weight
