Analysis of an opto-mechanical system

Hello,

@berkeman

I have created a presentation about the thermal analysis of an infrared seeker head and need feedback from experienced engineers. The presentation should not be longer than 10 min, so I have limited myself to the most necessary:

-Check function (spec. image quality, stability,..)

-Gain insights

-Derive suggestions for design changes

Operating modes, transportation, storage

MIL-STD-310 (Global climatic data for the development of military products)

MIL-STD-810 (Test method for determining the environmental impact on equipment)

Mass, dimensions, cross-sectional area, surface area, surface emission

conductivity, specific heat, thermal expansion coefficients, convection coefficients

Can you help me to find the most important points here?

Here I also need information about the most important steps in a thermal analysis of an opto-mechanical system.

Hello,

@berkeman

I have created a presentation about the thermal analysis of an infrared seeker head and need feedback from experienced engineers. The presentation should not be longer than 10 min, so I have limited myself to the most necessary:

**Slide1 preparation / data collection:**

a) Main objectives of the analysis:a) Main objectives of the analysis:

-Check function (spec. image quality, stability,..)

-Gain insights

-Derive suggestions for design changes

**b)Environmental conditions:**Operating modes, transportation, storage

MIL-STD-310 (Global climatic data for the development of military products)

MIL-STD-810 (Test method for determining the environmental impact on equipment)

**c) Characteristics of the system elements (with picture):**Mass, dimensions, cross-sectional area, surface area, surface emission

conductivity, specific heat, thermal expansion coefficients, convection coefficients

**Slide 2 Modeling**

a) Simplified analytical calculations as a starting point:a) Simplified analytical calculations as a starting point:
