摘　　要：在系泊船模在波浪中的运动水工模型试验中,设计了一种试验测量仪器。该仪器可用于测量波浪作用下系泊船模的六自由度运动量。将6支拉绳式位移传感器固定在船模上方,每个传感器的拉绳均与下方的船模固定。船模晃动时会带动6根拉绳。根据6根拉绳长度变化和前一时刻船模的姿态,可以计算出船模运动的六自由度运动量。经波浪试验表明,该仪器可以很好地反应系泊船模的六自由度运动量,达到了预期的目的。The measuring device was designed in naval tank experiment.The ship motion of six freedom acting with wave can be measured by this device.Six rope-type sensors were fixed with the top of naval tank.Six ropes were pulled when ship model was sloshing.According to length variation of six ropes,six freedom was calculated.It is indicated that six freedom of ship model could be responded with the measuring device.
