Ítem Analysis of the procedure for suspension evaluation of civil armoured vehicles: Reliability and safety driving criteria(Inderscience Enterprises, 2013-01-01) Martinod, R.M.; Betancur, G.R.; Mesa, J.F.; Benavides, O.M.; Castañeda, L.F.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)The present study exposes an analysis of the suspension system technical state evaluation for civil vehicles that have been subject to armouring processes. Such evaluation is performed through a mechanised revision established by state regulation and is based on the method defined by EuSAMA. The development of this analysis focuses on establishing the existing relation between the ballistic resistance integrated to a vehicle and the dynamic effect exercised for the modification of its mass, according to two reliability/safety driving measurement criteria: (i) tyre-road adhesion index and (ii) tyre excitation phase angle. The study proposes new elements to the current procedure established to evaluate the suspension of civil armoured cars considering the two measurement criteria, which can be acquired by a standard commercial suspension tester machine.

Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)The technical state of the damping elements for a vehicle having twostage suspension was evaluated by using numerical models based on the multibody system theory; a set of virtual tests used the eigenproblem mathematical method. A test was developed based on experimental modal analysis (EMA) applied to a physical system as the basis for validating the numerical models. The study focused on evaluating vehicle dynamics to determine the influence of the dampers' technical state in each suspension state.Ítem Failure analysis of a car suspension system ball joint(PERGAMON-ELSEVIER SCIENCE LTD, 2011-07-01) Ossa, E.

Departamento de Ingeniería de Producción; Materiales de IngenieríaÍtem Failure analysis of a car suspension system ball joint(PERGAMON-ELSEVIER SCIENCE LTD, 2011-07-01) Ossa, E. A.; Palacio, C. C.; Paniagua, M. A.; Universidad EAFIT. Departamento de Ciencias Básicas; Electromagnetismo Aplicado (Gema)[No abstract available]Ítem Suspension and landing gear failures(Elsevier Inc., 2015-01-01) Ossa, E.A.; Paniagua, M.; Universidad EAFIT. Departamento de Ingeniería de Producción; Materiales de IngenieríaFailure of landing gears in aircrafts represents approximately a 10% of the total of failures reported for the aerospace industry. This chapter discusses the main causes of these failures, their prevention, and a complete analysis of three cases of failure of this kind of components. On the other hand, failures of suspension systems in vehicles represent approximately a 13% of the total of failures for the automotive industry. In this industry, it is a common practice to replace failed parts without any further investigation of the root causes of failure, which can make the amount of failures to be underestimated. This chapter will discuss the main types and causes of failures of suspension systems. One case of failure of this kind of components will be analyzed and discussed in detail. © 2016 Elsevier Ltd.
