英文摘要：

In order to speed up the new plan seeking for construction machinery, based on the system of similarity norm of machine-soil system, the mathematical model for simulation design is established by applying similarity transformation deduction, the major parameters of which include rated load, tractive force and capacity, et al. The algorithm model is obtained by integrating the formula with major parameters including machine weight and engine power. As a result, rapid simulation design calculation of structure excellent sample machines is realized, and the levels of technology and economy and performance parameters of of new machines are predicted.
