The invention belongs to the technical field of helicopter skid type undercarriage design, and particularly relates to a helicopter skid type undercarriage drop simulation method. The skid type undercarriage system comprises a front cross beam, a rear cross beam, a skid tube, a simulated fuselage, a drop plane and a limiting piece; sledge pipes are arranged on two sides of the bottoms of the front cross beam and the rear cross beam; the simulation machine body is arranged above the front cross beam and the rear cross beam; the simulation machine body is connected with the front cross beam and the rear cross beam through limiting pieces; the falling plane is arranged below the sledge pipe; the simulation method is realized by adopting simulation software and comprises the following steps of: 1, establishing a finite element model of the skid type landing gear system; 2, material setting of the skid type undercarriage system is carried out; 3, setting unit attributes of the skid type landing gear system; 4, bou
