PURPOSE:To prevent the occurrence of vibration of a weight stand and to improve measuring accuracy, by transmitting moving load of the weight stand provided with a rocket motor to a load detector through a buffer. CONSTITUTION:A weight stand 33 provided with a rocket motor 35 is moved along a guard rail by the driving force of the motor 35. Hereby, a piston rod 48 of a buffer 36 put between the stand 33 and a load cell 49 provided to a frame 27, is moved interlockingly with the stand 33 and the moving load of the stand 33 is transmitted to the cell 49 through a buffer solution of the buffer 36. On one hand, the load by the static friction force before movement of the stand 33 and dynamic friction of the moving time, is transmitted to the cell 49 through a rocking plate 32 also. By this constitution, the vibration of the stand 33 is prevented and the noise involved by the vibration is not generated and then, the accuracy of the combustion test of the rocket motor is improved. |
