本文比较了两种方案和三种平衡计算原则后,提出了以变角速的双轴平衡机构平衡单缸机往复惯性力的新方法。并以W—190型柴油机为例进行计算,发现使用这种方法可以平衡的往复惯性力约为97%。在这台柴油机上加装了这套平衡机构进行试验,实测结果证明机身振动显著减小。 After comparing two schemes and three principles of balance calculation, this paper proposes a new method to balance the reciprocating inertial force of a single cylinder with a biaxial balance mechanism with variable angular velocity. Taking the W-190 diesel engine as an example, it is found that the reciprocal inertia force that can be balanced by this method is about 97%. In this diesel engine is installed on the balance of this mechanism for testing, the measured results show that the body vibration significantly reduced.
