1、了解升降平臺模型，并記錄其編號。分析機械的實際構造和運動情況，查明該機構由多少個構件組成，找出機架及原動件，并根據相連接的兩構件間的接觸情況及相對運動的性質，確定各個運動副的類型，并依次標上字母。
Learn lifting platform model, and record its number. The actual construction and analysis of mechanical movement, identify the agency by the number of components that identify the rack and the original moving parts, and the nature of the exposure and the relative motion of the two components are connected between each deputy campaign to determine the type, and sequentially labeled with letters.  

2、確定構件數目，將升降平臺摸型緩慢地運動，從原動件開始，沿著運動的傳遞路線依次在各構件上標上數字編號。循著運動的傳遞路線分析該機械原動部分的運動如何經過傳動部分傳遞到工作部分。
Determine the number of members, the lifting platform slowly to touch-type motion, starting from the original mover, moving along the relay route on each member in turn marked figures. Follow the movement of the transmission line analysis of how the movement of the mechanical moving parts after the original transmission parts delivered to the working part.   

3、仔細觀察各構件間的接觸情況及相對運動的特點，用規定的符號將各運動副表示出來，用直線或曲線將同一構件上各運動副元素連接起來，用箭頭標出機構原動件在圖示位置時的運動方向，繪制出所要畫的機構運動簡圖，選擇與機械的多數構件的運動平面相平行的平面作為繪制機構運動簡圖的投影面。
Features and careful observation of the contact condition of the relative movement between the members, with a predetermined symbol vice movements represented by a straight line or a curve motion of each the sub-elements are connected on the same member, indicated by an arrow in FIG original moving parts mechanism position shown in the direction of movement, and draw the kinematic diagram to be drawn, sport plane selection and mechanical components of most parallel kinematic plane as drawn sketch of the projection surface. 

4、 分析升降平臺運動的確定性。計算升降平臺的自由度數，并將結果與實際升降平臺的原動件數相對照，若與實際情況不符，要找出原因及時改正。
Analysis lifting platform movement certainty. Number of degrees of freedom is calculated lifting platform, the original number of the movable member and the results contrasted with the actual lifting platform, if inconsistent with the actual situation, to find out the reasons for timely correction.

5、選擇適當的比例尺，根據該機械的運動尺寸，確定各運動副之間的相對位置，
Select the appropriate scale, according to the mechanical motion of size, to determine the relative positions of deputy campaign between
