Abstract: In view of the market demand of the self-propelled power supply vehicles, and many problems such as the voltage and current load characteristics of present mobile power plants being unable to meet the operating requirement, the low engine utilization rate, majority of them being not self-propelled, singleness of function, suitable to lesser regions, on the basis of the existing self-propelled vehicle chassis, utilizing modern design theory and method, by virtue of computer analyzing and processing software such as ANSYS, ADAMS and Matlab, and through optimal matching of engine and driving system, an electronic governing system is developed, rubber crawler travel mechanism is rationally configured, a variety of auxiliary facilities on job site are equipped, a 100 kW series multi-purpose self-propelled power vehicles of high stability for all-terrain are manufactured. Its whole dynamic property and economical efficiency are simulated and optimized, the load stability of the power, the passing ability and utilization rate of power supply vehicles are markedly increased, the applicable regions are expanded. The prototype is tested and authenticated by related national quality inspection administration, which confirms that all indexes of the vehicle meet or exceed the requirements of national standards. Now the products are batch produced stably and win good comments from users.
