Finite Element Analysis and Experimental Simulation of Chassis Mounted Platform for Off-Road Wheeled Combat and Transport Utility Vehicles

Abstract

Chassis mounted platform is an intermediate component between vehicle chassis and chassis mounted shelter, and is intended to act as a levelled base for shelters. Shelters in combat vehicles provide a closed stipulated environment to computerized tracking systems, sophisticated defense combat equipments to suit the operational and environmental requirements during warhead situations. Platform carries transfers and sustains unevenness in load arising from the road or soil irregularities during off-road vehicle travel. Present work deals with development, evaluation and improvement of one such platform for 8x8 vehicles. In this work, the platform under consideration is designed to accommodate two shelters, each being secured to the platform using standard twist locking arrangements. Securing locations are dependent on the size and weight of the commodity to be placed inside shelter. Major design ruminations of the platform include nature and pattern of load, flange orientations of channel sections, span between webs of consecutive channels, axle load distribution and vehicle geometry constraints as ground clearance and departure angle. Finite element analysis is carried out in to order evaluate stress and deflection in the present platform configuration. Experimental strain measurement at critical locations on the platform is carried at Automotive Research Association of India (ARAI) to evaluate the performance of the platform under specified load-speed conditions. Relation between experimental stress values and strain gauge locations on the platform is assessed for different load magnitudes.

Methodology of explanation of tactical and technical requirements for means of evacuation of weapons and military equipment

“…A number of works by both domestic and foreign scientists are devoted to the study of the formation of tactical and technical requirements for the means of evacuation and transportation of damaged samples of WME, in particular, in the work [1] the analysis of researches concerning scientific and technical support of development of armament of radio engineering armies and their combat and technical maintenance is carried out, and the publication [2] analyzes the means of evacuation, which are in service with the armed forces of the Russian Federation and the Republic of Belarus, and the main focus in this work is on the world-famous system multilift the literature [3] methods for solving problems of modernization of WME, synthesis of properties to assess the feasibility of modernization and search for rational solutions are considered, and the work [4] concerns the development, evaluation and improvement of the platform for 8x8 cars. Some aspects of this issue are presented in work [5], which is devoted to determining the directions of creation of basic wheeled chassis for the installation of weapons and for use of the chassis as a vehicle for transporting armored weapons and equipment, and in works [6][7] describes the development of a quantitative model the relationship between defense research and their costs.…”

Напрямки Розвитку Озброєння Та Військової Техніки Щодо Підвищення Рівня Захищеності

“…Так у роботі [3] висвітлено погляди на наявну систему забезпечення Збройних Сил України ОВТ, звертається увага на своєчасне прийняття вмотивованих і обґрунтованих рішень щодо реформування системи забезпечення, а у роботі [4] обґрунтовано актуальність дослідження конструктивних особливостей бойових броньованих машин (ББМ) типу MRAP, розглянуто основні конструктивні відмінності ББМ щодо забезпечення захищеності і як впливає рівень бронювання на тактико-технічні характеристики. Робота [5] стосується розробки, оцінки та вдосконалення платформи для автомобілів 8х8. У ній розглянуто платформу, призначену для розміщення двох відділень, кожне з яких закріплене на платформі.…”
