SMAT2008V47SOME ASPECTS CONCERNING TESTING AND ASSESSINGOF THE AUTOMOBILE PLATFORMS FOR FURTHER DEVELOPMENTOF THE LAROM WEAPON SYSTEMMinu MITREA, Marin MARINESCU, Dănuţ GROSUAbstract: Since a NATO member, Romania <strong>de</strong>veloped new weapon systems, to face the <strong>de</strong>mands of the mo<strong>de</strong>rnbattlefield. In this respect, Romania <strong>de</strong>veloped a weapon system having as its main component a multiple rocketlauncher, able to <strong>de</strong>liver its fire at ranges of 40...60 km. Nevertheless, several rocket launchers won’t be, by themselves,a weapon system. There<strong>for</strong>e, the LAROM weapon system is completed with an ammunition carrier-and-loa<strong>de</strong>r and afire-control vehicle. In lack of a reliable carrying vehicle, after acquiring some rocket launchers, MoD gave up theprogram and asked the system’s integrator to look <strong>for</strong> better solutions in this respect. So, at its turn, the integrator (S.C.AEROSTAR S.A. Bacău) looked <strong>for</strong> an improved carrying vehicle. Consequently, S.C. ROMAN S.A. Braşov, issuedthree brand new 6x6 carrying vehicles that are Euro 3, MAN engine powered, all of them having ZF, manual shiftinggearboxes. The paper presents the basics of the testing programs that have been <strong>de</strong>veloped by the LACEBAT TestingLab of the Military Automotive and Logistics Department, from the Military Technical Aca<strong>de</strong>my, Bucharest. It alsoprovi<strong>de</strong>s comparative data between the old and the new powered weapon system, i.e. the rocket launcher itself (since inthe old powered version only the rocket launcher was manufactured).

In or<strong>de</strong>r to validate the ABS/ASR system working algorithm and to accentuate the influences overthe braking or starting processes with and without ABS/ASR, a planar dynamic mo<strong>de</strong>l was <strong>de</strong>signed <strong>for</strong> a single wheelof the passenger car. This simplified mo<strong>de</strong>l has two inertial elements: a wheel in rotation and a mass in translationalmovement (the “quarter” vehicle).
