Remote controlled material handling equipment (RCMHE)

September 29, 2011

Prior to the introduction of the so called “Material handling equipment” humans had to perform physical labor to carry out heavy duty tasks. This could be made possible by employing a huge number of workers. However, when the goods came in bulk unloading and loading turned out to be a very time consuming affair. The use of Material handling equipment in logistics has played a significant role in making the loading and unloading activities easier and faster.

Ask yourself the question “Why are ‘Remote controlled’ material handling equipment used?” and almost instantly you arrive at the logical answer that the chief benefit would be allowing personal to control their machine from a safe distance.

Remote control can be achieved by two different modes:

1)     Radio frequency (RF) Signals

RF signals are further divided into two categories.

a)     Narrow-band system  b)  Spread spectrum system.

2)     Infrared light

Infrared method works by transmitting a beam of light

Infrared mode of radio control is preferred over RF signals because of the safety and precision that it offers. Since the infrared method works by transmitting a beam of light, once the beam is out of sight, the beam is obstructed and the controls turn off.  That is, the operator must always be in view of the RCMHE, which in turns aids safety as the full visibility of the operator over the machine is critical. Precise, in the sense that with the use of RF technology there is always a chance of interference with other signals and might lead to accidents, Infrared remote control makes this type of mistake impossible.

Applications:

1)      Transfer of components from one container to another especially fragile objects

2)      Transfer of  hazardous/explosive objects

3)      Operation in high temperature environment

 

Although it is advantages to use RCMHE, proper training for the staff handling the RCMHE is a prerequisite to ensure safe working.

Mangalore, October 22: Association of Integrated Mechanical Engineering Students (AIMES) was inaugurated recently at Srinivas Integrated Campus, Mukka.

After formally inaugurating the Association, Deepak Prabhakar, Senior Manager of Mechanical Department, MRPL said that students need to participate in extracurricular activities to expose themselves to the outer world. Along with computer and technical skills, they should cultivate skills of conversation and communication, he said.

He also advised that student associations should aim at developing overall personality and self confidence of an individual.

In his presidential address Dr. Shreeprakash B, Principal, Srinivas School of Engineering, opined that students should cultivate the habit of personal life-skills, leadership quality, and cultivate the capacity to start self employment.

Vivekananda Huddar, Head of the Mechanical Department, briefed about the objectives of the Association.

President of Association Parivesh Rathod welcomed the gathering and Secretary Pramod proposed the vote of thanks. Tilak E compered the programme.

Reliability

September 16, 2011

It is defined as the probability that a given system will perform it’s function adequately for it’s specified period of lifetime under specified operating conditions.

01-reliability-analysis-life time analysis-life time warranty

Common measures are :

1. Failure rate.

2. Mean time between failures(MTBF)

3. Survival percentage.

Failure Rate:

01-the bathtub curve-failure rate vs time - Reliability test-failure analysis-calculate life time of a product

Rate which components of population fail.

R(t)=Ns(t)/Nf(t)

Where,

Ns(t)- No. of components that survived during time ’t’

Nf(t) – No. of failures that occurred during the same time.

01-web- failure analysis-unexpected failure-operational fracture-failure rate

01-preheater-tube-failure-failure rate-circumferential cracking-probability of failure

Mean time between Failures(MTBF):

01-mtbf-mean time between failures-measurement of reliability-repairable items

The reciprocal of the failure rate(1/λ).

Where

λ —-Failure rate.

Failure rate = (No.of failure )/(Time period during all components were exposed to failure)

 

Reliability Analysis:

Failure Mode and Effect Analysis(FMEA)

01-FMEA-failure mode and effect analysis-effective analysis-risk priority number-severity number-probability number-reliability analysis

Purpose :

1. To recommend design changes.

2. To identify design weakness.

3. To help in choosing alternatives.

01-space-shuttle-failure mode-effects-criticality analysis-fmea-reliability test

Four Stages:

Ist Stage – System boundaries and the scope of the analysis is decided.

IInd Stage – Data Collection

Ex: Specification,Operating Procedure,Working Conditions.

IIIrd Stage– Preparing the component or parts list.

IVth Stage – Failure frequency and the functions of the part identified,causes of       failures,Failure detection.
