Through the redesign and adopting the new electronic technique on the generator of a farm transport vehicle, what is more important, its voltage output is stabilized to a definite range, which solved the low speed lighting problem of the vehicles.
According to analysis of the ideal brakeage distribution and the practical brakeage distribution of front and rear brakes of farm transport vehicle,and the synchronous adhesion coefficient, the author indicates the unsafe reasons of farm transport vehicle when it brakes.
In reference to ISO5349, test and analysis of vibration are carried out on the handbar of tri-wheeled agricultural vehicle Type GM-500. It is found that the handbar vibrates drastically, that the engine is the most important vibration source and that the first and secondary rotating frequencies as well as the combustion frequency in the vicinity of 67.5 Hz of the engine are major exciting frequencies to the handbar.
This paper insroduces a testing researchfmethod of brake system and corresponding results for improving the brake system design of an agricultural vehicle of type "JM122" and raising the brake performance of the vehicle.
Based on measurement, and theoretical analysis and calculation of combined bendine torsion loads on axle of farm vehicle HT-12Y, a combine programmed load spectrum is worked out for loading the axle in fatigue tests, and its fatigue life estimated under the action of combined alternating loads.
