分析中採用了patran中的多點約束（ mpc ）技術，有效地模擬了活塞銷與小頭孔內表面、曲柄銷與大頭孔內表面以及連桿體與大頭蓋接觸面的力學接觸狀態，並對連桿進行合理的約束。The main popular theoretical method adopted to study end - plate connection is finite element technique under monotonic loading at present. this paper applies nonlinear ( material, geometry and contact ) finite element method to analyze the behaviors of connections under cyclic load at fist time. contact elements are set between end plate and column flange, screw cap and neighborhood plane, bolt bar and hole
對于端板連接的理論分析，目前國內外的研究主要局限在單向加載有限元分析范疇，本文首次採用三維非線性（包括材料、幾何與狀態非線性）有限元對端板連接進行了循環加載分析，端板與柱翼緣間、螺栓頭（帽）與相鄰板件間、螺栓桿與孔壁間都設置了反映邊界狀態的接觸單元。With different clearance value, displacement curves and velocity curves of generalized coordinates as well as slider displacement error curves in a motion period are obtained. these curves are discussed. results show that if manufacturing cost is kept invariableness, in order to improve precision of mould - cuting, fitting precision of joint connecting the crank and coupler has priority to be considered to increase
採用四階rong - kuta法求解連續接觸模型的動力學方程，得到了一個運動周期內運動副間隙取不同值時，各廣義坐標的位移、速度曲線和滑塊位移誤差曲線，並通過曲線分析，得出了要提高模切機主切機構精度，在相同加工成本條件下，應優先考慮提高曲柄與連桿鉸接處的配合精度的結論。4 ) have studied the natural vibration characteristic of the piston - connecting rod - crankshaft while keeping in touch with the condition each other adopting systematic methods.,
4 ）採用系統的方法研究了活塞-連桿-曲軸三者在相互接觸條件時，在不同轉角下的固有振動特性。Considering joint clearances at both ends of the coupler, a continuous contact model is developed by modeling clearance as a massless rigid link. a set of strongly nonlinear equations is obtained by using angle displacement of clearances in kinematic pairs as generalized coordinates. four order rong - kutta method is adopted to solve the dynamical equations of continuous contact model
考慮曲柄與連桿、連桿與滑塊之間運動副間隙，將運動副間隙看成是一無質量的理想桿，利用連續接觸模型進行建模，採用運動副間隙角作為廣義坐標，得出一組強非線性方程組。Abstract : based on spline function method, the spline finite element formulation for the contact - impact problems is proposed. in order to get the formulation, the b3 spline function is used to distribute the contact problem, and numerical examples are analyzed to show the effectiveness of the method. because the spline function has double characteristics including analytical and numerical, and good continuity and high correctness, a little unknown number and high efficiency, the spline functions are used to set the displacement of the bar, and the whole structure equations are constructed directly. it is convenient to analyze dynamic response of the structure by using the method
