Power flow characteristics of a hydro-mechanical transmission system(HMT) were investigated for tracked vehicle. in steering. A HMT consisting of two hydrostatic pumpㆍ motors(HST), several planetary gear trains and steer differential gear was considered. In order to obtain the direction and magnitude of the power flow of the HMT, network theory for the general power transmission was used. Network model for the HMT in steering was developed, which consisted of shafts, nodes and transmission elements such as clutch, gear, etc. Power flow analysis procedure consists of two stages: (1) traction force analysis in steering, (2) power flow analysis in HMT. Torque and Speed of every transmission element of the HMT was determined from network analysis. Also, efficiency, mechanical and hydraulic power loss including HST, were obtained. In addition, the regenerative power flow resulting from steering can be studied in graphic display. The power flow analysis program(PCSTEER) developed in this work can be used as a useful design tool for the tracked vehicle with HMT.<br/>

추진시스템 전자제어장치를 개발하고 점검하기 위하여 실제신호와 유사한 형태의 전기적인 신호를 모사하여야 한다. 추진시스템에 사용되는 신호로 엔진속도, 터빈속도, 다양한 온도신호, 압력신호 및 LVDT/RVDT 위치신호 등이 있으며 실제신호와 유사한 수준으로 전기적인 신호를 모사하는 신호모사 장비의 개발에 대한 내용이다. In order to develop and inspect the electronic controller of propulsion system, It must emulate the electronic signal similar to actual signal. The applied signals on propulsion system are engine speed, turbine speed, various kinds of temperatue signal, pressure signal, LVDT/RVDT position signal and so forth. Contents are the development of emulator that simulate the electronic signals similar to actual signals.

In this paper. a network theory for generaltransmission systme was extended considering the direction of power flow. Also, a modified network model was suggested for a node with 4 shafts in order to verify the power flow. Based on the extended network theory, a simulation program was developed to analyze a hydro-mecaanical tranmission(HMT) system consistion of two hydrostatic pump motors, severeal planetary gear trains steer differential gear. The simulation result showed that the extendednotwork analysis program develped can predict the power circulation as well as the magnitude of torque and speed for each transmission element and can be used design tool for genaral power transmission system.
