摘要
根据挖掘机的工作原理，从数学的角度阐述了挖掘过程的轨迹方程应是对数螺线。依据妆始的挖掘边界条件压挖装状态，确定了方程中各参数值，使方程具有工程意义。从此建立了新设计体系，代替了原来以工况为主的设计体系，实现设计思想有创新。
According to the working principle of a excavator, this paper describes mathematically that the trace equation of digging processes is of logarithmic helix. On the basis of initial boundary conditions of digging and state of digging-lading, the values of the paramters in the equation are determined, which makes the equation practical. In such a way, a new design system of working device is established to substitute for the the traditional one which is mainly based on the typical operating mode. The design idea is renewed.
