معادلات دیفرانسیل همزمان و ارتعاشات چند بعدی چهارمین کتاب در معادلات دیفرانسیل معمولی با کاربرد در مسیرها و ارتعاشات، مجموعه شش جلدی است. به عنوان یک مجموعه، آنها چهارمین جلد از مجموعه ریاضیات و فیزیک کاربردی در علم و فناوری هستند. این کتاب چهارم از دو فصل (فصل 7 و 8 مجموعه) تشکیل شده است.
فصل اول مربوط به سیستم های همزمان معادلات دیفرانسیل معمولی است و بیشتر بر مواردی تمرکز دارد که دارای ماتریسی از چند جمله ای های مشخصه هستند، یعنی خطی. سیستم هایی با ضرایب توان ثابت یا همگن. روش ماتریس چند جمله ای های مشخصه برای سیستم های همزمان معادلات تفاضل محدود خطی با ضرایب ثابت نیز اعمال می شود.
فصل دوم نوسانگرهای چند بعدی خطی را با هر تعداد درجه آزادی از
جمله میرایی، اجباری و رزونانس چندگانه در نظر میگیرد.
نوسانگرهای گسسته ممکن است از تعداد محدودی از درجات آزادی به
زنجیره های بی نهایت گسترش داده شوند. نوسانگرهای پیوسته با
امواج در محیط های همگن یا ناهمگن، از جمله امواج الاستیک،
صوتی، الکترومغناطیسی و سطح آب مطابقت دارند. ترکیبی از انتشار
و اتلاف منجر به معادلات فیزیک ریاضی می شود.
Simultaneous Differential Equations and Multi-Dimensional Vibrations is the fourth book within Ordinary Differential Equations with Applications to Trajectories and Vibrations, Six-volume Set. As a set, they are the fourth volume in the series Mathematics and Physics Applied to Science and Technology. This fourth book consists of two chapters (chapters 7 and 8 of the set).
The first chapter concerns simultaneous systems of ordinary differential equations and focuses mostly on the cases that have a matrix of characteristic polynomials, namely linear systems with constant or homogeneous power coefficients. The method of the matrix of characteristic polynomials also applies to simultaneous systems of linear finite difference equations with constant coefficients.
The second chapter considers linear multi-dimensional
oscillators with any number of degrees of freedom including
damping, forcing, and multiple resonance. The discrete
oscillators may be extended from a finite number of
degrees-of-freedom to infinite chains. The continuous
oscillators correspond to waves in homogeneous or
inhomogeneous media, including elastic, acoustic,
electromagnetic, and water surface waves. The combination of
propagation and dissipation leads to the equations of
mathematical physics.
