FEM modeling and simulation of three different configurations have been considered for integration plate in assembled payload conditions. Structural analysis of the plate under the simulated boundary conditions was carried out. Plate deflection at critical point was worked out. Depending upon the results obtained optimum plate thickness with stiffeners at the various locations was incorporated on the integration plate to meet the system requirements. Keywords: Laser Based Range Finding System, payload. I. INTRODUCTION The range finding systems find wide application in meteorology, air pollution monitoring and control, military application, surveying application, oceanography etc. Unlike micro wave radar, laser beam is highly directive and can be used to measure the range of small targets. For survey purpose highly accurate range finding systems with maximum accuracy are available based on laser. The basic principle of laser range finder is to measure (to & fro) travel time of laser radiations (light) between range finder and object. If “d” is the distance of target from range finder and “t” is the time for travel of light (to and fro path), and “c” speed of light, then t= 2d/c and distance, d =ct/2. Following are the different types of subsystems of Laser based range finding system: 1. Trans-receiver Module 2 Ranging and display Module 3. Power Supply Module As all the above subsystems are going to be mounted on an integration plate. The design and analysis of this integration plate is quite critical from the system performance point of view. The design optimization of this plate has been carried out taking into consideration all the above three subs systems (payloads), system requirements, and working conditions. Analysis of the plate for deflection at various critical points caused by different subsystems under static and dynamic conditions was carried out using CAD tools. Taking into consideration the size, weight, and system requirements necessary supporting ribs/mechanical structure were incorporated to minimize the deflection at critical points within acceptable limits.
