  2. So this base isolation technique has profound prospects. unfortunately there exist definite difficulties in the calculation because of the nonlinear of the base friction force. now, both the equivalent damping method and the numerical calculatin of the vibration response of the base - isolated buildings are frequently used in the calculation of the seismic response of the base - isolated building. however both of them have certain drawbacks. in this paper, the response of the building with base - isolation system is derived by the method of fourier expansion for the friction force and the earthquake response. at the same time, the sliding vibration character of inertia of a single mass structure and the sliding vibration response of a muti - mass structure are discussed. the stable condition of the sliding base isolation system of a structure is given. in the end, two circes of base fixation and base sliding are analyzed by adopting ansys

    本文利用對摩擦力和地震響應進行付氏級數展開的方法導出了基底具有摩擦隔震系統的地震反應。同時，文中從研究單質點結構的滑動振動慣性力入手，進而對多質點結構體系滑動振動反應進行探討，分別給出了結構滑動隔震的自身穩定條件。最後，本文利用ansys對基礎固定和基礎滑移隔震兩種工況進行了動力模擬模擬分析，進一步證實了基礎滑移隔規律。

  4. Furthermore, it was the first time to make a systemic analysis and study to the motion rule and affected factors of this kind of transformer. with the applications of relative polar method and equal view angle method, the transformer that satisfies the requirement of transmission rate and output motion is synthesized. thus, an original non - frictional stepless speed regulator with a 1. 5kw input power, a 1500 rotation speed, a constant150output rotation speed and a maximum 300 output rotation speed was achieved

    在此基礎上利用相對極點法和等視角法按傳動比及輸出運動的要求對轉換器進行了綜合，得出了輸入功率1 . 5kw ，輸入轉速1500 ，額定輸出轉速為150 ，最大輸出轉速300的新型的非摩擦式無級變速器的基本尺寸參數並應用adams軟體對其進行了優化；最後對該非摩擦式無級變速器進行了過約束分析，提出了新型的非摩擦式無級變速器無過約束分析的機構運動副的配置方案。
  5. In distilled water and 1 mol / l hc1 friction coefficients of sic / sic were smaller than 0. 02, and 0. 1 in 1 mol / l naoh. in air at 50 % relative humidity firction coefficients of the five sliding pairs tested fluctuated between 0. 6 - 0. 8
